1. Introduction
The KegLand RAPT Temperature Controller (Model KL22927) is an advanced device designed for precise temperature management in home brewing and other applications. This controller connects to the RAPT web portal, allowing for remote monitoring, logging, and control of connected heating and cooling devices. Its color screen provides clear temperature displays and graphical representations of temperature settings and profiles, simplifying the process of executing complex temperature steps.
This plug-and-play unit features two clearly marked power sockets for heating and cooling, enabling simultaneous control of a fridge or heating element to maintain optimal temperatures. Each power outlet is rated for 10 Amps at 250 Volts (2400 Watts maximum).
2. Safety Information
- Always ensure the device is connected to a power source that matches the specified voltage and current (10A 250V).
- Do not immerse the controller unit in water or other liquids.
- Keep the device away from direct heat sources and open flames.
- Ensure all connections (power cables, temperature probe) are secure before operation.
- Do not attempt to open or repair the device yourself. Refer to qualified personnel for servicing.
- Use only the provided temperature probe or a compatible replacement.
- Unplug the device from the power outlet before cleaning or when not in use for extended periods.
3. Package Contents
Verify that all items are present in the package:

4. Product Overview
4.1 Controller Unit
The RAPT Temperature Controller features a clear color screen and intuitive control buttons for easy operation. The back of the unit includes a removable mounting plate for various installation options.
4.2 Ports and Connections
The bottom of the controller unit houses the input and output ports:
- Power Input: Connects to the main power supply via an IEC cable.
- Temperature Probe Input: For connecting the included temperature probe.
- Blue Output Socket: For connecting a cooling device (e.g., fridge).
- Red Output Socket: For connecting a heating device (e.g., heating pad).
5. Setup
5.1 Mounting Options
The RAPT Temperature Controller offers versatile mounting options. The mounting plate on the back can be unscrewed and reoriented to suit your needs:
- Panel Mount: Integrate the controller into a control panel.
- Hanging Point/Hook Mount: Hang the controller from a hook or similar fixture.
- Fridge Top Mount: Securely place the controller on top of a fermentation fridge or brewery setup.
5.2 Connecting the Controller
- Connect Temperature Probe: Insert the temperature probe into the designated input port on the controller. Ensure it is fully seated.
- Connect Heating/Cooling Devices: Plug your heating device into the red output socket and your cooling device into the blue output socket.
- Connect Power: Use the provided IEC power cable to connect the controller's power input to a suitable 10A 250V power outlet.
6. Operating Instructions
6.1 Basic Temperature Control
Once powered on, the controller's color screen will display the current temperature. Use the 'Up' and 'Down' buttons to navigate menus and adjust settings. The 'Enter' button confirms selections, and the 'Back' button returns to the previous screen.
6.2 PID Heating Function
The RAPT Temperature Controller includes a PID (Proportional-Integral-Derivative) heating function. This advanced control algorithm minimizes temperature fluctuations and reduces the risk of scorching, particularly with higher-powered heating devices, by precisely managing power output to maintain the target temperature.
6.3 RAPT Wifi Connectivity
The controller is RAPT Wifi compatible, allowing integration with the RAPT web portal. This portal provides comprehensive features:
- Remote Monitoring: View current temperature and device status from anywhere.
- Data Logging: Record past temperature data for analysis.
- Temperature Profiles: Program and execute complex temperature step profiles.
- Future Projection: Visualize projected temperature profiles.
To connect to the RAPT portal, follow the on-screen instructions on the controller to connect to your local Wi-Fi network. Once connected, register your device on the RAPT web portal.
6.4 Mobile Application
Enhance your experience with the RAPT mobile application, available for both Android and Apple devices. The app acts as a mobile wrapper for the RAPT portal, optimizing the interface for mobile screens and providing push notifications.
- Android App: Download from Google Play Store
- Apple App: Download from Apple App Store
7. Maintenance
- Cleaning: Wipe the controller's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is unplugged before cleaning.
- Probe Care: Handle the temperature probe carefully. Avoid bending or damaging the probe tip. Clean the probe after each use, especially if it comes into contact with liquids.
- Storage: Store the controller in a dry, cool place when not in use.
8. Troubleshooting
8.1 Common Issues
- Controller not powering on: Check if the IEC power cable is securely connected to both the controller and the wall outlet. Ensure the wall outlet is functional.
- Incorrect temperature readings: Verify that the temperature probe is correctly inserted into its port and that the probe tip is properly positioned in the medium being measured.
- Heating/Cooling device not activating: Ensure the heating/cooling device is plugged into the correct output socket (red for heating, blue for cooling) and that the device itself is functional. Check the controller's settings to ensure the target temperature and hysteresis are correctly configured.
- Cannot connect to RAPT Wifi: Ensure your Wi-Fi network is active and within range. Double-check the Wi-Fi password if prompted. If issues persist, try restarting your Wi-Fi router and the RAPT controller.
