The RAPT Bluetooth Thermometer is compatible with Gen 4 BrewZilla’s, RAPT Temperature
Controllers and RAPT Fermentation Chambers allowing you to make smarter and more automated
decisions on how to control the brewing or distillation process. The RAPT Bluetooth Thermometer is
able to perform many functions when bonded with a RAPT controller including, but not limited to:
•Measuring core grain temperature of your BrewZilla to more accurately control the heating
elements according to the mash temperature.
•Measuring still head temperature and controlling the BrewZilla to turn the elements off once
your target temperature is hit and your distillation run is over.
•Measuring core fermentation temperature and controlling your RAPT Fermentation
Chamber or RAPT Temperature Controller heating and cooling.
The RAPT Bluetooth Thermometer will not work without one or more of the devices listed above.
WARNINGS - IMPORTANT INFORMATION!
•Do not install the batteries in the incorrect orientation.
•Do not submerge in or subject any part of the device to liquid other than the thermometer
probe.
•Only clean the probe with recommended cleaners and sanitisers including: StellarClean,
StellarOxy, StellarSan, Phosphoric acid and Super Kill Ethyl Sanitiser Spray.
•Do not use any non-approved probes with this Bluetooth thermometer.
•Changes or modifications to this unit which are not approved by KegLand may result in
warranty being void.

ASSEMBLY & INITIAL START UP
Battery Installation
Slid the cover off the cover off the battery compartment and then install the two supplied AAA
batteries ensuring that they are installed in the correct orientation.
Once the batteries have been installed the device should beep and the screen should automatically
power on.
Power ON/OFF
To power the device ON/OFF, hold down the button for at least 3 seconds.
Temperature Probe Installation
Plug the probe into the 3.5mm female jack on the RAPT
Bluetooth Thermometer.
When the temperature probe is plugged into the device the
display will show the temperature measured by the probe.
If three dashes are shown on the display then this means that
the temperature probe may be unplugged or faulty.

Sleep Mode
The device will enter “Sleep Mode” after 10 minutes of
inactivity. While in sleep mode BLE will be shown on the display
to conserve battery. While in Sleep Mode the device will still
transmit data via Bluetooth to any bonded devices.
Press the button to wake the device up and show the measured
temperature on the display.
Operation Instructions
1. Install the batteries and temperature probe and remove the black plastic tip on the probe
before use.
2. Power on the device by holding down the button below the display for at least 3 seconds
3. Bond the device with your RAPT Temperature Controller, RAPT Fermentation Chamber
Controller or Gen 4 BrewZilla. Bonding instructions are shown below.
4. Submerge the temperature probe into the liquid you wish to measure. The temperature
measured by your RAPT Bluetooth thermometer will then automatically transmit to your
bonded device.
5. Set the RAPT Bluetooth Thermometer to be the controlling temperature sensor for your
BrewZilla or RAPT Temperature Controller.

Bluetooth Bonding to a RAPT Device
To utilise the Bluetooth functionality of the RAPT Bluetooth Thermometer you will need to bond it
via Bluetooth to a RAPT Temperature Controller, RAPT Fermentation Chamber or Gen 4 BrewZilla
Controller. Follow the steps below to bond your RAPT Bluetooth Thermometer to a RAPT enabled
device:
1. On your RAPT Temperature Controller, RAPT Fermentation Chamber or Gen 4 BrewZilla
enter the Menu and navigate to Settings and press ‘Select’ on the Bluetooth enabled setting
to enable Bluetooth on the controller.
2. On your RAPT Temperature Controller, RAPT Fermentation Chamber or Gen 4 BrewZilla
enter the Menu and navigate to Bluetooth, then navigate to RAPT Temp [Temperature]
shown in the unbonded devices. Press Select and when prompted press Select again to
bond to this device.
You can successfully bond multiple RAPT Bluetooth Thermometers with your RAPT enabled
controller as per normal. Each RAPT Bluetooth Thermometer has a unique mac address which is
displayed in the Bluetooth settings when the thermometer is powered on.
Setting the RAPT Bluetooth Thermometer to be the
controlling temperature sensor
The RAPT Bluetooth Thermometer can be set as the controlling temperature sensor of your RAPT
Controller. To set the RAPT Bluetooth Thermometer as the controlling temperature sensor follow
the instructions below.
1. Bond the RAPT Bluetooth Temperature Controller to your RAPT Temperature Controller,
RAPT Fermentation Chamber or Gen 4 BrewZilla Controller
2. Go to Settings on the RAPT Temperature Controller, RAPT Fermentation Chamber or Gen 4
BrewZilla Controller
3. Navigate to Select Temperature Sensor and press Select. Then use the up or down buttons
to scroll through the available bonded devices until your RAPT Temp is selected. Then press
Select to confirm the setting of the RAPT Bluetooth Thermometer as being the controlling
temperature sensor.
Once you have set the RAPT Bluetooth Thermometer as the controller temperature sensor your
RAPT Temperature Controller, RAPT Fermentation Chamber or Gen 4 BrewZilla will then cycle the
heating or cooling (if applicable) on, according to the temperature measured by the RAPT Bluetooth
Thermometer and not by the built-in probe on the RAPT Controller or BrewZilla.

Using the RAPT Bluetooth Thermometer to measure and control mash
temperature
The RAPT Bluetooth Thermometer can be utilised to achieve a more accurate mash temperature
during your brew day.
To nail your mash temperature, measure the core temperature of the mash and set the RAPT
Bluetooth Thermometer to be the controlling temperature sensor for the BrewZilla. When the RAPT
Bluetooth Thermometer is set as the controlling temperature sensor the elements will turn On/Off
when required based on the set temperature on the controller and the temperature measured by
the RAPT Bluetooth Thermometer within the core of the mash.
This allows a more accurate mash temperature to be maintained and meaning you can nail your
recipe.
1. Bond the RAPT Bluetooth Thermometer to your BrewZilla Controller
2. Set the RAPT Bluetooth Thermometer as the controlling temperature sensor.
3. Set your required mash temperature on your BrewZilla controller.
4. Insert the probe of the RAPT Bluetooth Thermometer into your mash.

Using the RAPT Bluetooth Thermometer to measure and control
distillation
The RAPT Bluetooth Thermometer is also a useful tool for monitoring the head temperature
of your distillation apparatus and subsequently controlling your boiler based on the
temperature in the still head and automating the overall distillation process.
To achieve this simply insert the probe into the thermowell in your distillation apparatus.
Then bond your RAPT Bluetooth Thermometer with your Gen 4 BrewZilla and set the
thermometer to be the controlling temperature sensor.
Adjust the set temperature of the Gen 4 BrewZilla to be when you want the distillation to
end (for example the temperature that you expect to begin collecting tails). Then once the
temperature in the still head hits this shut off temperature the BrewZilla will then turn off
the heating elements until the temperature drops below the hysteresis value set on your
BrewZilla.
You may need to adjust the Allowed Sensor Diff. setting in the BrewZilla controller to ensure
that the wash in your boiler continues boiling throughout the distillation process.
Allowed Sensor Differential
The Allowed Sensor Diff. setting in the RAPT Controller is the maximum deviation (differential) from
the set point that the built-in temperature probe of the bonded RAPT enabled device is allowed to
reach before the heating/cooling is turned off to prevent excessive temperature over/undershoot.
The heating/cooling of the RAPT Controller will then turn back on based on the hysteresis settings of
the controller to increase or decrease the measured temperature until it reaches the desired set
point.
More detailed information regarding how the Allowed Sensor Diff. setting works can be found in the
video below:
