The RAPT Temperature Controller offers a number of different mounting options offering the versality to be able to change how to controller is mounted depending on what you are using the controller for. The controller is provided as standard with a mounting plate which is installed onto the controller out of the box. This mounting plate can be removed if you would instead prefer to mount the controller onto the wall for example.

To remove the mounting plate, slide the mounting plate down towards the bottom of the controller.

If you prefer to mount the RAPT temperature controller to your wall however you did not want to damage the wall by screwing into it you can attach the mounting plate to the wall using strong double-sided tape and then slide the RAPT temperature controller onto the mounting plate to secure it.

Screw two screws into the wall using the following template as a guide. Then simply hook the controller onto the screws using the mounting points provided on the back of the controller.

Please use this link to download and print the

Unscrew the hanging hook and rotate it 180 degrees, retighten and attach the controller to the wall using this hanging hook. This can be mounted to your wall using a screw or hanging the controller onto a hook which is already mounted on your wall for example

Another option for mounting the RAPT Temperature Controller onto a wall is to drill a screw through the recessed holes below the front face plate which continue all the way through to the two mounting holes at the back of the controller.

These holes can be identified by running your finger along the face plate in the area shown below. You can then either peel away the face plate and use an 8G x 60mm countersunk screw or you can drill straight through the face plate using an 8G x 60mm or 10G x 60mm countersunk screw as shown below:

WARNING: Ensure the temperature controller is unplugged from the wall socket before changing the orientation of the cables

If you want to neatly mount the RAPT Temperature controller vertically onto your bench or into a custom designed cabinet/panel for example, the orientation of the cables can be quickly and easily rearranged. To achieve this, undo the 4 screws which hold the front and back housings together and then pull the two housings apart.

Unscrew the two screws which hold the slotted blanking plate to the housing and remove the slotted blanking plate.

Move the cable glands to the back of the unit and secure in place with the slotted blanking plate, then secure the slotted blanking plate to the housing using the two screws. Then reassemble the front and back housings and secure with screws

You can then custom design your own panel or cabinet to mount this temperature controller into with the outlets and wiring now exiting out the back of the controller allowing for a very neat mounting arrangement.

Alternatively, if you want to mount this on your bench top or on top of your Temperature Controller you can use the mounting plate as a stand to keep the temperature controller in an upright position. Simply slide the temperature controller housing onto the guides on the mounting plate as shown:

The RAPT Temperature Controller comes as standard with a 2m extension temperature probe. This probe is calibrated out of the box. You may wish to calibrate this for a number of reasons such as to improve accuracy around the temperature range in use, or if you have replaced the original temperature probe for any reason.

To calibrate the temeprature probe:

1. Enter the menu by pressing Select

2. Set up two glasses of water. Ice water to one glass and add hot water to the second glass

3. Use the Up or Down arrows to navigate to Settings and press Select

Insert the temperature probe of the RAPT Temperature Controller into the glass of ice water while simultaneously measuring the temperature of the ice water using a calibrated external thermometer such as a digital instant read thermometer (KL23320). Wait for the temperature reading on both the RAPT Temperature Controller and the external calibrated thermometer to stabilise as much as possible.

Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature measured on the external calibrated thermometer.

Press Select to lock in Calibration point 1 and move on to Calibration point 2.

Insert the temperature probe of the RAPT Temperature Controller into the glass of hot water while simultaneously measuring the temperature of the hot water using a calibrated external thermometer. Wait for the temperature reading on both the RAPT Temperature Controller and the external calibrated thermometer to stabilise as much as possible.

Then adjust the temperature shown on the RAPT Temperature Controller to match the temperature measured on the external calibrated thermometer.

Press Select to lock in this calibration point 2

Alternatively, Bonding a via Bluetooth and using this as the tmperature probe is ideal as this unlocks the ability to have powerful, customised Fermentation Profiles with steps that can be triggered by temperature, time, gravity and rate of change of gravity!

In the event that you revert back to the standard probe that is preinstalled in the RAPT Temperature Controller, you can manually reset the temperature probe to the default settings.

1. NTC beta: 3950

2. NTC ref. temperature: 298.2

3. NTC ref. resistance: 100000

You can also select Forget Calibration in Settings. This will revert any saved calibration settings to default.

Manual Operation of the RAPT Temperature Controller

If you do not intend to connect your device to the RAPT Portal and hence do not want to utilise the WiFi functionality you can operate the Temperature Controller completely manually via the buttons on the display.

To remove the prompt requesting you to register your device to the RAPT Portal you will need to disable Wi-Fi in the settings. To do this press Select to enter the menu, then select Settings, then navigate using the arrows to the Disable Wi-Fi setting. Press Select to disable the Wi-Fi and the controller will then restart automatically.

If you decide you don’t want to register your RAPT Temperature Controller to the RAPT portal and hence not use the Wi-Fi functionality of the controller you will in turn lose a lot of the functionality of the controller which is offered through the RAPT Portal. This includes features such as setting up complex temperature profiles which are run automatically and logging past temperature profiles.

At the home screen press the Up or Down buttons to adjust the target temperature. The Temperature Controller will then automatically send power to the heating or cooling terminals to power on your heating or cooling device to maintain this target temperature.

NOTE: This is possible only if the device is not currently running an assigned profile.

The WiFi connectivity of the RAPT Temperature Controller allows you to monitor, track and start a complex temperature profile involving multiple steps remotely through the RAPT Portal. In order to fully utilise the capabilities of this device you should connect your RAPT Temperature Controller to your Wi-Fi network and register it to your account on the RAPT portal at

This will allow you to track and monitor your fermentation in real time remotely without needing to walk over to your Temperature Controller. It also allows you to setup and send complex fermentation profiles involving multiple steps to your RAPT Temperature Controller which will then automatically run through this profile and adjust the set temperature as required.

In order to have access to this WiFi functionality you will need to sign up for a RAPT Account, connect your RAPT Temperature Controller to your WiFi network and register your device on your account on the RAPT Portal by following the

Other Settings that can be adjusted directly in the RAPT Portal include Heating and Cooling On or Off, Heating and Cooling Hysteresis, Fan and Light operations/modes, Compressor and Mode Switch Delay and Telemetry Frequency.

To access these Settings in the RAPT Portal select the Edit button for your RAPT Fermentation Chamber in the RAPT Portal.

The temperature set point can also be set through the RAPT Portal or a profile session can be started from the RAPT Portal which will automatically begin the profile you have created.

To change the temperature set point in the RAPT Portal simply enter the desired Set Point target and press Set

Once you have registered your RAPT Temperature Controller on the RAPT Portal you can then log telemetry from the device and set up complex temperature/fermentation profiles involving multiple steps.

To setup a fermentation profile on the RAPT Portal select My Profiles and then Create New Profile. Then add your fermentation profile steps such as primary fermentation, diacetyl rest, dry hop, cold crash etc.

For a detailed guide on creating complex and powerful profiles please refer to

Your RAPT Temperature Controller will automatically check for and install firmware updates when turned on and connected to a WiFi network.

To check the firmware version on your RAPT Temperature Controller, press Select to enter the menu and then navigate to Diagnostics.

To manually update the firmware in the event that this is not up to date, navigate to Settings and then navigate to Check for OTA Update. Your device will then automatically download and update the most current available firmware.

NOTE: You must be running the latest firmware in order to register your RAPT device

Profiles are a key component of the RAPT system. Profiles are powerful tools that can be customised to a great degree, allowing extremely fine control over all aspects of brewing/fermentation

Profiles are created in the. There are also Global Profiles that can be imported and customised. Once a profile is created in the RAPT Portal, it can be sent to the corresponding RAPT device using Send Profile To Device from the My Profiles screen. Alternatively, you can select Start Profile Session for the RAPT Temperature Controller in the Dashboard. This will send the Profile to the device and also begin the Profile automatically.

The RAPT ecosystem is intended to be largely controlled remotely, and thus there are more powerful controls in the RAPT Portal than on board the RAPT Temperature Controller.

Once you have registered your RAPT Temperature Controller on the RAPT Portal you can then log telemetry from the device and set up complex temperature/fermentation profiles involving multiple steps.

Bonding a RAPT Pill to send telemetry is a powerful and robust way to really leverage the versatility of the RAPT ecosystem.

Please refer to this video for a detailed guide to Bonding your RAPT Pill to your RAPT Fermentation Chamber or Temperature Controller.

, it can be selected in the Settings menu as one of the available Temperature Sensors. Once selected in this menu, temperature control will be ceded to the selected Bluetooth enabled RAPT device, rather than the internal temperature probe. In addition, on the TFT display the current (most recent) Graity and Temperature reading will be displayed. The internal (built in probe) temperature is also displayed. NOTE: this is not displayed in Graph Enabled Mode.

Once the Pill has been Bonded and selected as the Temperature Sensor of the device, powerful Profile features are unlocked.

You can set triggers such as Gravity or Gravity Velocity, as well as Time for your fermentation control.

The RAPT Temperature Controller is designed to be largely controlled through the RAPT Portal.

There are various on board functions which can be accessed directly through the on board menu.

To use the on board menu, use the Up or Down buttons to navigate. Use the Select button to select or enter a function once highlighted. Use the Cycle/Back button to escape from a Menu option or return to the prvious screen. Selecting Back will not save any changes.

This option will only be available when the RAPT Temperature Controller is not registered to the RAPT Portal. For a step by step guide to registering your RAPT Temperature Controller please refer to

To access currently running Profiles, or Profiles that have been uploaded to the device, navigate to and select

If your RAPT device boots up but continually ‘loops’ back to the start up logo, this indicates that the device is stuck in a ‘boot loop’

This can happen for several reasons including but not limited to a failed firmware download, power interruption during install, poor network strength.

A Boot Loop can occur on any RAPT device with a screen – including but not limited to RAPT Fermentation Chambers, RAPT Temperature Controllers, Gen 4 RAPT BrewZillas.

A Boot Loop issue is quite easily rectified.

Generally, a Boot Loop can be resolved by resetting NVS.

An NVS reset is performed using the following steps.

If updating the firmware persistently fails or throws an error, and all troubleshooting steps have failed, then try using your mobile phone as a Hotspot to resolve this.

Using the phone as a Hotspot will typically solve firmware update issues of this kind

1: It helps eliminate potential network or modem/router issues which can cause problems that can be hard to isolate and resolve

2: It can help eliminate signal strength or poor WiFi connection issues as the phone can be positioned right next to the RAPT device when in Hotspot mode.

To connect to the phone Hotspot and update the firmware there are a few steps to follow

1. On the phone, turn WiFi OFF. When troubleshooting firmware download or network issues, we do not want to use the same network thus the phone must be disconnected from the WiFi network in order to do this

2. Enable Personal Hotspot (sometimes just called Hotspot) on your phone. This is typically located under the WiFi or Network menu in the Settings menu of the phone. On IOS this is under Settings/Personal Hotspot. The menu names will vary on Android depending on device

3. Enable Maximise Compatibility (on IOS) or 2.4gHz Network Only
