Reviving this thread now that it is already cold ...
It is 13'C in the morning and it would be convenient to have a nice warm air blowing inside. At least the heated seats help.

Note that the AC is still working fine ...

While the set temperature is set at 32'C, AC button OFF, recirculated air and in AUTO, i observed the values in INPA and ... :

- Engine coolant temp is playing around 99'C
- Outdoor temp - 24'C
- Indoor temp - 26'C
- Heat exchange sensor - 26'C
- Water valves - OFF at all times
- Aux water pump - ON at all times

I thought "The water valve opening times are 0 ms at max. COLD and 3600 ms at max. WARM."

Are the water valves normally open?
