Menu Guide | RAPT Fermentation Chamber

The RAPT Fermentation Chamber 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 Return button to escape from a Menu option or return to the prvious screen. Selecting Back will not save any changes.

Register Device

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

Profiles

To access currently running Profiles, or Profiles that have been uploaded to the device, navigate to and select Profiles in the menu. From this menu, available Profiles can be started, stopped and paused.

Active profiles can also be skipped to another step or reverted to a previous step. Please refer to Profiles for a full guide.

Settings

The following options are available in the Settings Menu.

To change any of the advanced settings enter the Menu by pressing Select . Once in the menu navigate to Settings and press Select

Up or Down buttons to adjust the set value for the setting. To save your setting hit Select . To return to the menu without saving choose Return

Some options are on/off toggles that can be activated or deactivated from the Settings Menu directly.

SETTING	PARAMETER

Bluetooth

Bluetooth needs to first be enabled in the Settings menu (above).

To Bond a Bluetooth enabled RAPT devices, use the Up or Down buttons to scroll to select the device. Choose Select button to Bond the device, or the Return button to cancel.

Once Bonded, the device will be visible in the Bonded section of the Bluetooth Menu. To Unbond, select the device with the navigation arrows and choose Select buttont to Unbond the device, or the Return button to cancel.

Once the device is Bonded, it can be selected in the Settings menu option 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.

NOTE: It is completely normal for there to be a temperature variance between the internal probe and the Bluetooth enabled RAPT device. This is because the Bluetooth device is measuring the temperature of the fermentation (typically), and the internal probe is measuring the air temperature of the RAPT Fermentation Chamber. This difference will be greater when the RAPT Fermentation Chamber is actively heating or cooling.

The Allowed Sensor Diff. Iin the Settings menu) sets the allowed temperature differential between the desired setpoint and the current temperature of the Fermentation Chamber. Cooling and Heating is disabled temporarily if this differential is exceeded. The default differential setting is 5°C. This value is suitable for typical use.

This differential can be altered in the Settings menu. If the temperature differential is exceeded, the RAPT Fermentation Chamber will suspend heating and cooling until the differential is reduced. The legend DIFF OVERRIDE will also be displayed when the display is in Graph Disabled Mode.

The RAPT Fermentation Chamber will suspend active cooling or heating and resume as needed – no intervention is required. Once the differential is reduced then heating and cooling will continue as normal.

Diagnostics

The Diagnostics menu contains information about the RAPT Fermentation Chamber. This includes such information as current firmware version, Wi-Fi network and signal strength, MAC address and IP address of the device.
