Frequently Asked Questions

Q: What should I do if the red LED on the appliance remains illuminated?

The device is indicating a fault. Switch the device off, wait for a short time, and switch it on again. If the red LED continues to illuminate, contact Truma Service.

Q: How do I tune the remote control to the IR receiver?

Insert batteries paying attention to polarity, ensure the setup symbol flashes (perform a reset if it does not), point the remote control at the IR receiver, press and hold the Setup button, and release it when the red LED on the IR receiver flashes.

Q: Can the air conditioning system be operated without the remote control?

Yes, there is an additional pushbutton (m) on the receiver that allows the unit to be switched on and off manually without the remote control. Switching it on via this button automatically resets the system to factory settings.
