What to do if my Meltem M-WRG-K ventilation unit is not running?

  If your Meltem Fan ventilation unit isn't running, it might be in safe mode due to an EMC fault. Try switching the unit off, waiting 15 seconds, and then switching it back on. It could also be due to an installation error, in which case you should have the wiring checked by a qualified electrician. A faulty switch, motor, or controller could also be the culprit, and should be checked by a qualified electrician.

Why doesn't my Meltem Fan switch to ventilation program "P3" or "P7" at the set times?

  Alicia HicksAug 6, 2025
  If the Meltem Fan ventilation unit does not switch to ventilation program "P3" or "P7" at the set times, it is possible that the time is wrong due to a power failure or because the ventilation unit was switched off at the mains switch. To resolve this, set the day and time in program "P8".

What to do if the air flaps on my Meltem M-WRG-K Fan do not open?

  Jeremy SmithAug 12, 2025
  If the air flaps on your Meltem Fan do not open after switching it on, it could be that the servomotor is not powered by the electronic circuit after a long stoppage or the first start. Try switching the ventilation unit off and on again. Alternatively, the air flap range of motion may be blocked by foreign bodies such as plaster or polystyrene. Carefully remove any obstructions, removing the cover if necessary.
