Hi, I have a comfort 1 Ultra system with a DM02 board and Fermax Cityline door station. This has given good service for a number of years but has recently given some issues.
The volume at the door station is very loud even with the local Fermax trim set to its minimum. The volume heard on the remote or local phone is now very quiet even with the Fermax trim set to maximum. I have looked at the tuning settings but don't seem to be able to have any effect.
I have checked all of the connection for corrosion and they look OK. The volume when listening remotely used to be very good, I could even hear children playing in the street. Could I have a fault in the Fermax station or are there any tuning options I could try?
