Malfunction

In the event of a malfunction, all control units of the ventilation unit display the unit malfunction, a warning symbol with error message appears on the touchscreen, and all 3 LEDs on the RLS 1 WR flash.

Faults registered by sensors may disappear automatically when the cause of the fault no longer exists, for example in the event of a temperature fault caused by too low an exhaust air temperature. The fault is recorded in the log book and sensor faults do not have to be acknowledged. All other faults rectified have to be acknowledged on one of the control units. Only then is the ventilation unit operable again.

With temperature sensor faults, wait to see whether the unit regulates itself again. Otherwise contact an authorised specialist installer.
