# Operation ## Using the Digital Controller The Digital Controller has 4 buttons which serve different functions depending on context **Cycle/Back - navigation between On Screen options. Exit without saving. Hold when prompted to advance Profile steps** **Select - Select the current option. Enter a Selection. Confirm a choice** **Up - Increase hightlighted variable** **Down - Decrease hightlighted variable** ### Manual Operation of the RAPT Fermentation Chamber If you do not intend to connect your device to the RAPT Portal and hence do not want to utilise the Wi-Fi functionality you can operate the Fermentation Chamber 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 Fermentation Chamber 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. ### Setting the Target Temperature Manually At the home screen press the Up or Down buttons to adjust the target temperature. The Fermentation Chamber 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. ### Operation of the RAPT Fermentation Chamber Throught the RAPT Portal The Wi-Fi connectivity of the RAPT Fermentation Chamber 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 Fermentation Chamber to your Wi-Fi network and register it to your account on the RAPT portal at[ https://app.rapt.io](< https://app.rapt.io>) This will allow you to track and monitor your fermentation in real time remotely without needing to walk over to your Fermentation Chamber. It also allows you to setup and send complex fermentation profiles involving multiple steps to your RAPT Fermentation Chamber which will then automatically run through this profile and adjust the set temperature as required. In order to have access to this Wi-Fi functionality you will need to sign up for a RAPT Account, connect your RAPT Fermentation Chamber to your Wi-Fi network and register your device on your account on the RAPT Portal by following the [setup instructions](/equipment/rapt-fermentation-chamber-or-user-guide/get-started.md) 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. ### Setting the Target Temperature via 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 Fermentation Chamber 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 [Creating and Editing Profiles](/profiles/creating-and-editing-profiles.md) ### Updating Firmware Your RAPT Fermentation Chamber will automatically check for and install firmware updates when turned on and connected to a Wi-Fi network. To check the firmware version on your RAPT Fermentation Chamber, 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** ### **Cleaning & Maintenance** The RAPT Fermentation Chamber will require little ongoing maintenance. Periodically check the undermounted drip tray and empty as needed. The outside of the RAPT Fermentation Chamber can be cleaned with a microfibre cloth. The inside of the chamber should be periodically cleaned with a mild detergent and a microfibre cloth. Ensure that the interior of the RAPT Fermentation Chamber is dried thoroughly between use. When not in use, ensure that the RAPT Chamber is clean. Best practice is to run it at low temperatures (\~2°C) in order to prevent mould or other issues when not in active use. Alternatively, when not in use, turn the RAPT Fermentation Chamber off at the wall. Ensure that the inside is clean and dry. Leave the door propped open when not powered on. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
