Frequently asked questions
This indicates that the fire protection function connected to terminals 6-7 has been activated.
Check if the overheating protection has tripped or if there is no supply voltage to the electrical heater.
The supply air temperature is below the preset set point (ERS and Supply air regulation) or Min SA temp (Extract air regulation) longer than 20 minutes.
The pressure across the AHU supply air filter has exceeded the preset alarm limit for more than 10 minutes.
Check if no impulses from the rotation detector are registered with the heat exchanger controller.
