Safety instruction

Introduction

The Pro-series Brewing Systems are built without compromise and is the product series that will always offer the highest level of flexibility, accessories and support for high-end solutions. The Pro-series consist of 3 models of different brew volumes, but they are all based on the same design principle and uses the same control system. The model name tells you the maximum recommended boil volume.

The key concept of these brewing systems is to use Tri-Clamp connections for tool-free and sanitary use. These offer great flexibility and offers the user the choice of different setups based on their preference.

This user manual will teach you how to prepare the system for the first time, how to use it, clean it and maintain it. You’ll also find an FAQ which addresses some questions that might arise during use.

First-time use

This chapter will tell you how to do the necessary steps to prepare your system for use.

Software

The control system for the Brewtools units will automatically receive software updates OTA (Over the air) as long ad the microSD card is installed (fitted as standard) and the unit is connected to Wi-Fi. Software updates are free and will incorporate bugfixes as well as new features. Since the software is under continuous development, we have decided to put all software related information available online.

Check out our user manual for the software:

Assembly

Unpack all the parts and place the brewing system upside down. Connect the power cables and other accessories like the return temperature sensor if you have that. The power cables should exit one of the service holes on the back of the system. The connectors have grooves that only allows the connector to be installed correctly. Do not use excessive force when plugging in the connectors. The optional return temperature sensor should go through the left silicone grommet that is already installed.

Flip the system the right way up and install the 3-way valve on the right side as shown below. Install the pump temperature sensor in the sensor adapter included with a gasket between the sensor and the adapter. Install the assembled sensor adapter on the rear outlet using a TC clamp with a gasket. Cut a part of the included silicone tube and install it between the sensor adapter and the pump. Make sure the tube has a nice curve to avoid blockages.

Install the gasket inside the bottom part of the sparge pipe and inside the mash hat as shown below. Use a small screwdriver or similar to push the gasket into place. The two gaskets are identical.

Install the large silicone gasket on the top of the sparge pipe as shown below.

Install two O-rings marked 18x2mm on the dip tube. The dip tube position can be adjusted freely. More on this subject in the “Using the system” section.

Install 3 blind caps on the open ports indicated below to avoid spilling. If you have extra valve(s), you can use the blind caps as preferred.

Install the 3 legs of the malt pipe using an allen key. Take note that the latches must be installed as shown below, and the wing nut must be used on the outside of the malt pipe. Alternatively, you can use a normal hex nut (not included). Install the silicone leg protectors to avoid scratching the bottom of the main tank during use.

Check for leaks

When filling the tank with water for the first time, make sure the taped threads on the pump and the sensor and heating elements gaskets are not leaking. Tighten if necessary. Also check that all TC clamps are tightly installed. The TC clamps might require tightening after use, due to the variations in temperature.

The filter

The filter included is made from expanded metal and might have some tension. Make sure the filter is flat. Flatten by hand if necessary. The filter should be cleaned before use to remove any residue from production.

Cleaning

The system should be thoroughly cleaned before use to remove polishing compounds and flux from the production process. Use Trisodium Phosphate (TSP) or other chemicals designed for this type of cleaning. Use a microfiber cloth to wipe all surfaces clean.

Passivation

We recommend passivating the steel before first-time use and 1-2 times a year. Use StarSan or similar acid-based chemicals. Fill the tank with lukewarm water. Use approximately 5ml StarSan per liter and leave it for 15-20 minutes.

Electrical connection

The system must be connected to an earthed socket with a residual circuit breaker. The control system supports two individual circuits. This feature is used on the B40pro 110V version, the B80pro and the B150pro due to the power requirements. The 240V versions of the B40pro runs on one circuit. The software offers the possibility to reduce the average maximum power to adapt to your circuit breaker limitations. You can choose between 10A, 13A, 15A and 16A for each circuit in the control system. Take note that this feature is based on standard voltage ranges, and variations may occur. We recommend testing different settings to find the best option for your location.

Simple function test

Fill the tank with water to cover the heating elements. Start the system in manual mode, and check the following:

• Temperature is correctly read by all sensors.

• The pump is running and can be adjusted on screen.

• Both heating elements are working (bubbles will form on the elements)

Using the system

This section explains how to use the system and gives you some good advice and recommendations for use.

For more information on different setups, please keep reading.

The control system

The systems are equipped with a 7” touch screen controller.The software can be updated for free through the built-in WiFi-module. When a new version of the software is available, it will automatically download and prompt the user to install it. If the user does not update right away, the new software will automatically be installed during the next startup.

The software is constantly being updated and new features added, so we will not cover the software in this user manual. Visit our website, www.brewtools.com to get the latest information on our Pro series software.

Valves

The system two T-type 3-way ball valves as standard. One side valve, and one bottom valve. The valves only close the port opposite to the direction the handle is pointing. If the handle points toward the middle port (as shown below), all ports are open.

The bottom valve has an extended handle which makes it possible to control from the right side of the control system. There is a sticker showing the flow based on the handle direction.

Dip tube

The dip tube position is adjustable and is normally used in the two positions shown below. We recommend positioning the dip tube in the upper position during mashing (especially when getting to know the system) to prevent the heaters becoming exposed. Exposing the heating elements will burn them and make them difficult to clean. They might also warp/expand due to the high heat. You can use the mash paddle or equivalent to push the dip tube down when the mashing is complete to get as much wort as possible pumped to the fermenter later in the process.

The Pump

The pump must never run without fluid in the chamber. This will cause damage to the magnetic impeller. In the beginning of the brew, air may be trapped inside the pump. To vent it, start the pump for a few seconds, stop it, and start it again. Repeat if necessary.

The pump must be installed as shown below. If you install it in a different position, it may affect the lifetime of the pump and make it difficult to vent the air out.

Preheating

We recommend heating the strike water before you install the center pipe and malt pipe for an even temperature. We also recommend circulating the water. The bottom valve handle must point to the “UP CENTER” position.

Crushing the grains

We recommend using grains that’s not too finely crushed to get the maximum flow through the grain bed. If you use a lot of special grains like wheat or oats, or you push the limits of the malt capacity, we recommend using rice hulls to increase the flow. The systems ship as standard with the coarse malt pipe filter and our recommended crush grade is 1.1-1.3mm.

Adjusting the malt pipe holders

The latches on the malt pipe may need some adjustment. They should move freely. Push them together to remove it from the latch holder. Adjust as necessary and reinstall the latch. The lower “pin” on the latch can be bent to position using a suitable tool

Lifting the malt pipe

The handle on the malt pipe is designed to be easily removed for cleaning and use of future accessories.

When lifting the malt pipe, make sure to only lift it high enough for the 3 latches to fall out and grab the edge. If you lift the bottom of the malt pipe higher than the center pipe, you may have difficulties getting the malt pipe seated back on the center pipe.

Different setups

The system can be set up in many ways. Below, we show 3 recommended options based on your accessories.

For more more details on the different setups, click at the link below.

Circulating during mashing

We always recommend resting the mash for 20 minutes after stirring in. In this period, we recommend circulating on the outside of the malt pipe. This is done by pumping the wort out through the lower left port and into the tank again on the upper left port. Use a dip tube to make sure the wort is circulating around the malt pipe. This will give you a more accurate temperature and prevent the heating elements burning the sugars. You can circulate through the counterflow cooler, if you have that.

By setting the bottom valve in a middle position shown below, you can circulate both outside the malt pipe and over the grain bed. With this solution you can set the pump power high (70-100%). Make sure the liquid level outside the malt pipe is stable and the heating elements never expose. As recommended earlier, the right dip tube can be set in the upper position to prevent this. Use the bottom valve to adjust the flow over the grains based on your flow rate through the grain bed.

Sparging

The system ship as standard with a sparge pipe. This pipe will sit outside the center pipe during the mashing process. When lifting the malt pipe, the sparge pipe will lift with it thus extending the center pipe. If you are sparging from a second water heater, we recommend connecting the sparge water on the front-facing port on the right 3-way valve. This allows you to pump the sparge water up the center pipe from the water heater, using the internal pump. Adjust the pump speed as needed. Make sure to not sparge with more water than the main tank can hold.

Boiling

Boiling can be done without a lid (open boil) or using a steam hat (accessory), if you have a ventilation system. You can also use the steam hat with our steam condenser (accessory) if you don’t have a ventilation system. During the boiling process it is important to adjust the power to get a satisfactory boil.

It is not recommended to use the pump during the whole boiling process, as hop pellets might clog the dip tube and pump. We recommend adding hop pellets on the opposite side of the pump intake. Whole hops should not be used directly in the tank as they will clog the pump intake. To disinfect the counterflow cooler and tubes, circulate through the cooler at least 10 minutes before starting the cooling process. Take note that you might need more power to keep the boil going when running the pump. Additionally, using the pump while boiling increases cavitation inside the impeller house causing more noise from the pump. It is therefore recommended to reduce the speed and not run it at full speed.

Cooling and transferring

You can use your preferred method for cooling the wort. An immersion chiller will work but will limit the whirlpool functionality.

We recommend using our custom counterflow cooler (accessory). It is designed for maximum flow to get a good whirlpool while cooling the wort. We recommend circulating through the counterflow cooler and back into the tank on the left side with a dip tube on the inside to create a whirlpool. When the desired return temperature is reached (can be measured with optional return temperature sensor), the wort is pumped directly to your fermenter by adjusting the left port 3-way valve (accessory, based on setup).

Cleaning

Regular cleaning is critical to keep the quality of your beer, and also to make your brewing system last you a long time. We recommend using a cleaning agent that does not harm Teflon (PTFE). Our 3-way valves uses PTFE bushings. PBW is not recommended to use for more than 30 minutes at a time.

During cleaning, we recommend using the pump to circulate through the counterflow cooler and all tubes. To empty the tank, remove the center pipe. The bottom valve handle is turned to drain the through the lower port. Use a bucket or a tube going directly to a floor drain.

If you have access to pressurized air, this is a great option to blow water out of the pump and pipes. Take note that the silicone tubes are not designed for high pressure.

Maintenance

Normal cleaning, rinsing and drying the tank, tubes, and cooler is sufficient. Tubes should be replaced when severely discolored.

If valves start leaking due to wear or stuck particles, we offer a rebuild kit for them.

O-rings and gaskets are replaced as needed.

The pump impeller should be checked from time to time to make sure no particles or grains are stuck.

The Pro Series Brewing Systems are designed for maximum flexibility. There are many ways of using the systems based on personal preference, what kind of accessories you have and how your brewing area is set up. Below, we will explain the principles of the system and some of the possibilites it gives you.

The tank and malt pipe are built from SS304 stainless steel with a thickness of 1.0/1.2mm. All outlets and ports on the tanks and valves are Tri-Clamp for maximum flexibility. The flanges and steel parts are cast in SS304 stainless steel, and CNC machined. The pump features a 24V brushless motor. It's quiet and powerful and the speed is controlled from the touch-screen. All tubes are 16x25mm food grade high quality silicone with high transparency. The entire system is designed and built to withstand years of use.

The basic principle in the system is a tank with a conical bottom with heating elements, a temperature sensor, a center pipe that's easily removable, an outlet port on each side and a 3-way valve in the bottom which makes it possible to circulate both over the grain bed and through the lower outlet and counterflow cooler or tube at the same time with full flow control. This makes it easy to maintain accurate temperatures outside the malt pipe as you circulate the wort around and up through the malt pipe and over the grain bed. The standard dip-tubes has two o-rings that makes them easy to adjust to the desired angle. If you brew with a lot of hops, you can adjust the dip-tube accordingly to prevent too much hops in the circulation and into the fermenter.

The right 3-way valve is used to choose the input for the pump. You can pump from the inlet dip-tube or from a second tank, usually for sparge water. In the standard setup without extra 3-way valves, this valve is also used to pump the wort to the fermenter.

The 3-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time. More on this is found in the user manual.

You also add an extra 3-way valve on the lower port. This makes you able to also clean the system without disconnecting any tubes. As an option you can use the third valve to bypass the cooler.

S = Temperature sensor

The 4-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time. More on this is found in the user manual.

You also add two extra 3-way valve on the lower port. This makes you able to also clean the system without disconnecting any tubes. You can also bypass the cooler without disconnecting any tubes.

With 4 valves there are also a lot of other possible setups depending on your need.

S = Temperature sensor

The 2-valve setup is based on using a valve on each of the side ports as shown below. You also add a dip tube inside the left port. This allows the wort to be pumped out from the lower port, through the counterflow chiller and back into the left side port through the valve.

With this setup you can take advantage of a whirlpool during cooling. Proteins and hops will form a cone in the middle of the tank thus decreasing your losses to trub. We also recommend circulating outside the malt pipe during mashing to improve temperature stability. By using the bottom 3-way valve in a middle position, you can split the flow around the malt pipe and over the grain bed. We recommend running the pump on 80-100% power and circulating both ways at the same time.

S = Temperature sensor

The Brewing Systems ships standard with one 3-way valve. This will normally be placed on the right side of the system, but if you don't want to sparge using the internal pump, you can install it on the left side to enable whirlpooling. Remember to get an extra dip tube if you want to use this option

By adding more valves, the flexibility will increase, and you can partly or completely avoid having to disconnect tubing or pipes during your brewday. What setup is the best, is subjective. A general advice is to start with the 2-valve starter pack and expand as you get more experience.

S = Temperatur sensor

Brewfather integration is made available from version 1.8.2 and newer. The integration make it possible to download a recipe from Brewfather to the Brewtools control system using a 5 character code. The recipe can then be stored and edited on the Brewtools control system.

Current integration does not have ability to send live brewing status back to Brewfather. However as part of a bigger ongoing Brewtools cloud intergation process this will likely be available in the near future.

Getting started

This section explain how to use the Brewfathe integration.

Step 1

Log in to Brewfather from your smartphone or computer. Open Settings.

Step 2

Enable "Brewtools" as Power-up in Brewfather under settings.

Step 3

Open the recipe you want to send to the Brewtools control system and click the green "brew" symbol.

Step 4

Change status to brewing.

Step 5

Click "Send".

Step 6

A 5 character code will show. The code will be valid for minimum 10 hours but will occasionally be deleted.

Note that Brewfather perform a recipe validation prior to generating the code. Validation errors will be displayed below the 5 character code for information.

Step 7

On your Brewtools controller, open recipes and click the Brewfather logo.

A popup will instruct the user what to do.

Enter the 5-character code and click OK.

The controller will then download the recipe and display it. It is always recommended to verify the content before running the recipe. If mandatory field are missing, they will be indicated with red background and you will need to fill it in before you can save it on the controller.

We regularly update the software for our control system to add new functions and features. The update is now done via WiFi (from version 1.01.00)

When a new version is available, your system will automatically download the update and let you know when it's ready to install. The Micro-SD card must be installed in the system as temporary storage for OTA updates The system ships with the MicroSD card pre-installed.

Update options

From version V01.07.01 it is possible to select Standard or Beta updates. If beta is chosen, you will get access to the very latest version with an increased risk of minor bugs. This option is suitable for those who want access to the latest functions and would like to help contribute with feedback so that we can make the software even better.

If you want well-tested functions and are concerned with stability, standard is recommended. Then you get well-tested software with minimal chances of bugs.

There is also a Dev. option. This option requires a code and is used for development testing and other special cases. If you experience having downloaded and installed a version with errors, you can choose Dev. and enter the code 11111111. Then the latest Standard update will be downloaded. This way, you can be sure that you can use the system without errors. Just remember to set the choice back to Standard or Beta afterwards so that you are guaranteed to get future updates.

How to update manually without WiFi

• Get an empty MicroSD card, formatted as FAT32

• Create a folder called "UPDATE" in the root of the MicroSD card

• Copy the *.bin file to the "UPDATE" folder (remove other files in folder)

• Turn the system off, and insert the MicroSD card into the slot on the control box

ERROR codes

If you get the error message "ERROR", the system has problems with updating. The code displayed will indicate what type of problem it has.

ERROR 01 - microSD card not installed or corrupt: Ensure the microSD card is installed on the back of the controller. If that does not help, try re-formatting the microSD card as FAT32. If that does not help, try another microSD with FAT32.

ERROR 02 - Downloaded file is invalid: Restart the system and try to download once more.

Downloads

Below you can download the latest version of the firmware

Firmware version

The current firmware version is displayed in the upper right corner on the home screen.

General design principles

The device user interface utilizes some general design principles.

1. Blue text and blue digits indicate that it can be pressed to control a certain function. White text or white digits indicates that it has no function. Blue text or digits can have either one or two functions.

   1. Push – First function

   2. Push and hold – Second function

3. Every place where the user is prompted to input a value a numeric pad will appear. The allowed numeric range is displayed at the top of the numeric pad. The displayed range is dynamic in terms of volume (liter/US gallon) and temperature (°C / °F) set in settings. If the user types an invalid number, nothing will happen when pushing «OK».

Common functions

Timer

A common timer function is made available from manual control, recipe, and delayed start. The timer has two functions.

1. Push – First function – set the timer

2. Push and hold – Second function – pause or resume timer

The timer made available in manual mode and recipe mode show remaining time in MM:SS format. Push to set a new time or push and hold to pause the timer. The timer blir start to blink to indicate that the timer is paused. Push and hold once more to resume the timer. When the time is up, the built in buzzer will sound according to the settings. Please see seperate section regarding settings.

The timer used for delayed start is slightly different. As it allows for up to 24 hours, the format is HH:MM:SS to provide a better user experience. Please see separate section for delayed start mode.

Pump control

The pump can be turned ON and OFF using the round button to the left of the slider. The slider is used to control the pump speed.

Heater control

The built-in heaters can be controlled in three different modes. Push the blue text to toggle between the modes.

1. AUTO – PID control limited by “Max current” set in settings menu.

2. MASH – PID control limited by “Mash mode power” multiplied by “Max current” set in settings menu.

3. MANUAL – Manual power control based on slider position. “Max current” set in settings menu define the scaling of power output.

The heaters can always be manually turned ON and OFF by pushing the round button on the left side of the slider.

The PID controller only use one temperature sensor at the time as process input. This means that it uses either the tank sensor or the pump in-line sensor. Indication to what sensor is currently in used as process input is indicated by the text above the actual temperature display.

In settings menu, a «sensor threshold» can be defined. This value is set in percentage and cohere to the pump speed. If the pump speed is set, using the slider, to a value higher than the threshold, the PID controller will automatically switch to using the pump in-line sensor. Similar, if the pump speed is set to a value lower than the threshold, the PID controller will automatically switch to using the tank sensor. This is to ensure that the in-line pump sensor is not used as process input if the pump speed is too low to provide a satisfying temperature control. It is always possible to override what sensor that should be used by pushing the temperature value. Selected sensor is indicated by the text above the actual temperature value. If sensor selection is overridden, the text will be displayed as red as opposed to blue.

Return temperature and mash temperature

In addition to the Tank- and Pump sensor, further two temperature sensors can be connected to the control system.

• Return temperature: This sensor is normally placed on the outlet of the counterflow chiller.

• Mash temperature: This sensor is manually placed into the grains while mashing.

The temperatures can be seen on the display by clicking on the upper left button. This will toggle between:

• Timer

• Return temperature

• Mash temperature

The following pictures show what happens when toogeling between the three displays.

Note that, the heater control cannot be controlled using return- or mash sensors input. At least not for now :-)

Manual control

Manuel mode is where you want to be if you want to have full control and continuous interaction with the equipment during the brewing process. Absolutely recommended as a starting point if you are new to the brewing equipment.

If you want to use the machine as a «Sous vide», manual mode is what you will be using.

From the manual mode screen, multiple functions can be performed e.g. changing the target temperature, toggle between the three heating control modes as well as using the timer. The pump can be controlled manually, and it is even possible to change settings live while brewing. By pushing the button with the snow crystal symbol, the timer will be swapped with the temperature from the third senor (accessory). The timer will still run in the background and by pushing the same button the timer will reappear.

Recipe

Recipe mode allow you to define the whole brewing session and let the control system guide you through the whole brewing process, keeping track of time and temperature. It is possible to store up to 20 custom recipes on the device. A new recipe can be added manually on the device by clicking the plus symbol. Recipes can also be imported from Brewfather by clicking at the Brewfather logo.

More details on how to import recipes from Brewfather, click the link below.

Stored recipes can be edited (pencil symbol), deleted (recycle bin symbol) or executed («play» button). Changes to recipes will not be automatically synchronized back to Brewfather.

Below is an example of how a recipe can look like. By taking the time to type the hop name and amount, you will experience that the text will appear during the brewing process which is of great help.

Recipe name – Give the recipe a proper name to make it easier to find it.

Strike overshoot temperature – Set the strike temperature if you want to compensate for the grain temperature absorption.

Boil time – How long the boil will last.

Cooling target – Target temperature for transferring to fermenter.

Sanitizing time – Get a reminder before the boil time is over to start the pump to circulate boiling wort through the counterflow cooler and hose line to sterilize it.

Mash water – Amount of mash water to be used.

Sparge water – Amount of sparge water to be used.

Sparge temperature – Temperature of the sparge water.

Mash steps – Define mash steps. Maximum 16 steps. Temperature must be incremental for each step.

Boil additions – Dine the additions used during boiling. Maximum 16 additions. Time for each addition is defined as how long it will be boiling. Time must be within total boil time defined above. Text is used as help as it will appear on the screen along the way.

Hopstand additions – Define hop stand. Set time to «0» to skip hop stand.

While running a recipe, notifications will pop up to guide you through the whole brewing session. A selection of notifications will also sound the buzzer according to settings.

Below are some examples of how running a recipe mode will look like.

Delayed start

Delayed start is a mode that allows you to schedule the machine to automatically heat your strike water beforehand, saving time on the brew day. The timer can be set to maximum of 24 hours countdown.

To use it, fill the tank with the right amount of mash water and set the timer to when the heating will start. Remember to allow necessary time for the water to heat, typically 30-60 minutes. When the set point temperature is reached, a safety mechanism is embedded to shut down the power after 4 hours. Time to shutdown will be displayed. This safety feature is implemented in case you forget or for some reason are prevented for conducting the brewing session. An additional safety feature is in place in case the sensors fails while delayed start is active. If sensor fails, the heaters will turn off or not starting at all.

Settings

Settings are made accessible from multiple places in the control system and will allow live changes without interrupting ongoing activity.

Settings are divided into 3 tabs.

General

Under the «General» tab you will find most of the day to day settings.

Alarm beeps – Number of beeps when the buzzer is activated. Choose; none, 1,3,5 or continuous.

Brightness – Select screen brightness in 20% increments from 40% to 100%.

Language – Select language. English, Norwegian, Italian, German, Spanish or French.

Sensor Threshold – Set the pump speed threshold where the in-line pump sensor automatically will be used as opposed to tank sensor as process input for temperature control. Select either 20%, 30%, 40%, 50%, 60% or 70%. It is still possible to override this, please see heater control section further up.

Max current 1 – Set the max power draw for power input 1. It is recommended to set it according to amperage rating on the circuit breaker feeding your power outlet. Available settings are: 10A, 13A, 15A and 16A.

Max current 2 – Set the max power draw for power input 2. It is recommended to set it according to amperage rating on the circuit breaker feeding your power outlet. Available settings are: 10A, 13A, 15A and 16A. Note! B40pro 240V version does not use this setting as it only has one power input cable.

Temperature unit – Select Celsius (°C) or Fahrenheit (°F).

Volume unit – Select Liter or US Gallon (1 US Gallon = 3.785 liters)

Mash mode power – Select power limitation used in Mash mode. This is a nice feature to reduce or avoid burning of the heating elements is cases of using wheat grains and/or step mash programs. Toggle to select either 30%, 40%,50%, 60%, 70%, 80% or 90% power during mash mode. The power reduction is related to any additional reduction set in Max current setting, so make sure total power available is enough to keep a stable temperature or perform a temperature increase during step mash at preferred pace. Other factors that will play a role is: surrounding temperature, whether lid is on or off, use of insulation jacket, volume in the kettle and voltage. It is recommended to test this prior to starting the brewing session, especially if you plan to use recipe mode as it will not allow you to change this on the fly.

To enable the power reduction, now called; mash mode, please see heater control section further up. If the text “MASH» is shown below the target temperature, you know it is activated. You will also see that the power slider indicator on the screen is locked to not exceed the percentage value set. For recipe mode, the system will automatically select mash mode.

Sanitizing time - Select how long before the end of boil the system should notify user to start circulating through the countercurrent cooler to disinfect the equipment. The value is used by default every time you create a recipe on the device or in cases where it is not defined when a recipe is downloaded from Brewfather.

Strike overshoot temperature - Select how much warmer the water should be for strike to compensate for the temperature effect of the grains when it is poured into the brewing machine. The value is used by default every time you create a recipe on the device or in cases where it is not defined when a recipe is downloaded from Brewfather.

Wi-Fi

To connect the device to a 2.4GHz Wi-Fi network with internet access, you will have to consent to Brewtools collecting anonymous data for the purpose of improving the services. Consent is given from the screen before filling in SSID and password.

Note! SSID is case sensitive meaning it distinguishes between small and capital letters. Additionally, some special characters are not supported by the system. Please check the keyboard on the device for allowed special characters.

Connection status is shown to the right. To disconnect the device from Wi-Fi, press the thick box. Last used SSID and password will be stored locally at the device.

Update

If the device is powered on and connected to internet, it will download new firmware as it become available:

• microSD card is installed in a slot on the backside of the control box.

• Connected to internet.

To check whether the device is downloading an update, please open the «Update» tab. When a new firmware is downloaded, user will get a notification. User then decide to install immediately or next time the device is powered on.

Secret settings

A secret settings menu is available from Manual mode or Delayed start. By pushing and holding the B-logo for more than 3 seconds you get access to settings that are considered more advanced and normally not relevant for most users. Offsetting temperature sensors and changing the PID controller parameters should not be done unless it is familiar to you.

Push «SHOW» button to see the default PID parameters.
