[bug] - picks temp from range if current hvac_mode offf

[swingerman]

Now I think there are problems in changing the preset_mode states for the machines that are on at reboot: the temperatures don't correspond to those set in the conf file.
I've also a warning in the logs: "No case matched when off"

I'm at work and I can't go into more detail. I'll do some tests in the afternoon (IT time) 👋
