My thermostat displays Error 5

A thermostat displaying Error 5 indicates it does not have a temperature sensor or is in an open circuit. The zone therefore loses the room temperature measurement. This leads to the zone being disabled for generating demand.

To confirm that it is not a part error, it should first be checked that no zones have been cross-labeled or incorrectly set. To do so, it is advisable to follow the procedure below:

Restart the zone and reassociate it to the system ( How can I reset a zone equipped with a Lite thermostat? ).

If the problem is not solved, restart the entire system and reassociate it ( How do I reset the entire system? ).

If the thermostat still displays Error 5 after these steps, the thermostat is faulty and should be replaced. Get in touch with the Airzone Technical Department ( Open a new ticket ).
