The RAPT Gen 4 BrewZilla 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.
This option will only be available when the RAPT Gen 4 BrewZilla is not registered to the RAPT Portal. For a step by step guide to registering your RAPT Gen 4 BrewZilla please refer to Getting Started
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.
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 |
|---|---|
Temperature Sensor | Select built-in probe or select any Bonded Bluetooth RAPT Pill & Hydrometer |
Show Graph | Toggles display between the graph or a numerical display |
Unit System | Toggles between metric or imperial data |
Graph zoom level | Select the date range displayed on the graph (default 7 days) |
Heating Hysteresis | Sets the heating hysteresis (range 0.0°C-10°C, default 2°C) |
Heater Enabled | Toggles heating on or off (when unchecked, the heater will not operate irrespective of other settings) |
Bluetooth Enabled | Toggles Bluetooth functionality on or off |
Allowed Sensor Diff. | This sets the allowed temperature differential between the built in probe and the current setpoint when using a Bluetooth device for temperature control (range 1°C-50°C, default 2°C). See Bluetooth Operation |
Sensor timeout | Sets the timeout if a Bluetooth device drops out (reverts to internal probe) (Range 5-1800 seconds, default 130 seconds) |
Sounds Enabled | Toggles device sounds on or off |
Calibration Point 1 | First Calibration Point (see Calibration) |
Calibration Point 2 | Second Calibration Point (see Calibration) |
Forget Calibration | Deletes saved calibration settings and restores defaults |

Heat I Coefficient | Enter desired integral PID coefficient (Default 0.0100) |
Heat D Coefficient | Enter desired derivative PID coefficient (Default 0.0750) |
Forget WiFi Config | Forgets existing WiFi config - useful if you change WiFI networks |
Disable WiFi | Disables WiFi (if you wish to not use the RAPT Portal and have only manual control) |
Clear Registration | Clears RAPT Portal registration (see Troubleshooting) |
Low Temp. Alarm | This is the temperature below which an alarm will sound (default -10°C) |
High Temp. Alarm | This is the temperature above which an alarm will sound (default 120°C) |
Check For OTA Update | Manually check and download any available firmware updates |
Bluetooth needs to first be enabled in the Settings menu (above).
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) Gravity 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 built in probe and the Bluetooth enabled RAPT device. This is because the Bluetooth device is measuring the temperature of the mash (typically), and the built in probe is measuring the temperature at the base of the boiler. This difference will be greater when the RAPT Gen 4 BrewZilla is actively heating.
The Allowed Sensor Diff. Iin the Settings menu) sets the allowed temperature differential between the desired setpoint and the current temperature of the RAPT Gen 4 BrewZilla's built in probe. Heating is disabled temporarily if this differential is exceeded. The default differential setting is 2°C. This value is suitable for mashing. For step mashing or mash out (for example) you may wish to increase this differential as this allows the temperature of the mash to be incresed at a faster rate.
This differential can be altered in the Settings menu. If the temperature differential is exceeded, the RAPT Gen 4 BrewZillawill suspend heating until the differential is reduced. The legend DIFF OVERRIDE will also be displayed when the display is in Graph Disabled Mode.
The RAPT Gen 4 BrewZilla will suspend active heating and resume as needed – no intervention is required. Once the differential is reduced then heating will continue as normal.
The Diagnostics menu contains information about the RAPT Gen 4 BrewZilla. This includes such information as current firmware version, Wi-Fi network and signal strength, MAC address and IP address of the device.
The About menu contains information specific to the firmware and software of the RAPT Gen 4 BrewZilla and associated devices, including but not limited to copyright information, acknowledgment of open source properties used, legal information etc.
To Bond a Bluetooth enabled RAPT device, 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.
