fan-only mode changes the target temperature to 0°C

[rehakf]

When I set climate:fan-only mode in homeassistant it changes the target temperature to 0°C (even if target min=16°C and max=30°C). Later when I set climate:cool mode, the target temperature is set to 0°C, then in a second it raises to 18°C, but the last used cooling target temp is lost (eg. 24°C).

When using remote control this doesn’t happen. Wired remote doesn’t make any changes in the target temperature when using fan mode (it just doesn’t display the target temp). Later when I set climate:cool mode, the last used cooling target temperature remains (eg. 24°C).

I found that this is probably due to the wired controller. When set to fan_only mode (no matter if by HA or wired ctrl) then the controller set the target temp to 0. Later if set to cool mode things are different:

• if set to cool by HA - cooling start with target temp=0°C immediately changed to 18°C
• if set to cool by wired ctrl - cooling start with the last known target temperature used for cooling which is probably memorised in the controller (eg. 24°C)

The code should reproduce the behavior of the wired controller in this case.
