How to reset, restart, power off, update firmware, and calibrate temperature readings.
Factory Reset
Warning: A factory reset erases all user data and settings - including WiFi credentials, sensor pairings, controller configuration, and all custom settings. Write down your setup configuration from the Info page before proceeding.
How to Factory Reset (Touchscreen)
Go to Settings.
Scroll all the way to the bottom.
Tap Factory Reset.
Tap Yes to confirm.
Wait a few minutes for the process to complete.
The device will erase all data and return to the controller configuration screen, just like when it was brand new. You will need to select your controller type and configure your heat stages again.
Reboot (Restart)
A reboot restarts the device without erasing any data. Your settings, sensor pairings, and configuration are all preserved. There are two ways to reboot:
Manual Reboot (Side Button)
Locate the small button on the right side of the thermostat.
Press and hold the button with a pen or paperclip for 4 to 6 seconds.
Release the button.
Tap Restart when the option appears on screen.
Touchscreen Reboot
Go to Settings.
Scroll down and tap Reboot.
Confirm by tapping Yes.
Power Off / Power On (Manual Only)
Sometimes you may need to completely power off the thermostat - for example, during storage or transport. This can only be done using the side button.
Power OFF
Locate the small button on the right side of the thermostat.
Press and hold the button with a pen or paperclip for 10 to 12 seconds.
The screen will turn off completely.
Power ON
Press and hold the same side button with a pen or paperclip for 10 to 12 seconds.
The screen will flash and the device will power on.
Wait for it to fully boot to the home screen.
Firmware Updates
The WalTech has two separate firmware systems that can be updated independently:
Thermostat Logic (FW) - Controls HVAC operations, relay switching, temperature logic, and sensor management.
Display Experience (VC/VN) - Controls the touchscreen interface, animations, menus, and visual elements.
The WalTech automatically checks for new firmware every 5 minutes when connected to WiFi or cellular. When an update is available, a pop-up prompt will appear on the screen asking you to Download Now or Cancel.
Important: Ensure you have a stable internet connection before starting a firmware update. Do not power off or interact with the device during the update process. Wait until the device fully returns to the home screen before using it.
Firmware updates typically take a few minutes. The screen may go blank or show a progress indicator during the process. This is normal.
Temperature Readings
The temperature sensor is located on the bottom left of the thermostat. It reads the air temperature immediately around the thermostat - not the average temperature of your entire RV.
It is normal for the WalTech reading to differ from other thermometers by +/-2F. Several factors can cause slight differences:
Direct sunlight hitting the thermostat
Airflow patterns near the mounting location
Proximity to windows, doors, or exterior walls
Heat from nearby appliances or electronics
Calibration
If you want to adjust the temperature reading to match a reference thermometer, go to Settings > Calibration. You can adjust the reading up or down to compensate for your specific mounting environment.
AGS, B&O, and Dry Mode
Dry Mode
Dry Mode is designed to reduce humidity inside your RV. When enabled, the system will operate the AC to run up to two degrees below your set point to reduce humidity based on your set humidity level.
Once the humidity reaches your target level, the system stops the dehumidification cycle and returns to normal operation.
Frequently Asked Questions
Yes. A factory reset erases all user data including sensor pairings, WiFi credentials, controller configuration, and all custom settings. You will need to set everything up again from scratch. Make sure to write down your configuration from the Info page before resetting.
The WalTech automatically checks for firmware updates every 5 minutes when connected to WiFi or cellular. If an update is available, a pop-up prompt will appear on the screen asking you to Download Now or Cancel. You do not need to manually check for updates.
The WalTech sensor is located on the bottom left of the thermostat and reads the air immediately around it. Differences of +/-2F are normal and can be caused by sunlight exposure, airflow patterns, proximity to windows, or heat from nearby appliances. You can calibrate the reading in Settings > Calibration to adjust it up or down.
