Hi I have a problem with this unit.
The resents cold weather has up set it as the unit seems to losses pressure over night (with code F.25 )only if the temperature is lowered by 5 degrees i.e if the unit remains switched on at 20 degrees all is fine but if you lower the temperature over any period of time then there is a loss off pressure within the system. ( normally overnight)
the only water to come out of the unit is through the condensate drain, please help as it unit is usually controlled through a timer/room thermostat.
