Manual and thermostat fan control

[KHWSommer]

Hi Patrick @patrickcollins12 ,
I am new to Github and I am not sure, whether this is the right place to ask you this.
I had been using your project quite successfully a few weeks ago (I want to use the warm air from an PV-inverter to warm my PV battery during the cold and humid winter months in my garage). I had uncommented the part for the manual control of the fan speed and - as you said in the readme - switched OFF the thermostat when I wanted to control the fan manually. This worked well until a few days ago. Now, even when I switch the thermostat OFF, the manual control only gives a short increase in rpm and then the rpm of the fan go back to zero, as if the thermostat was not switched OFF. I suspect that there was an update of the platforms somewhere which broke this. If I delete all the thermostat code from your project, I can control the fan manually without problems as before. Do you have any advise how I can have the option again to use both thermostat and manual control together as before?
Thank you very much for this project. It's my first Home Assistant/ESPHome project and I am having fun because of your great work.
Klaus

Hmm.... I'm not near my devices at the moment and traveling.

May I suggest you watch the logs carefully:

esphome logs <pv_config.yaml>

Then once you've done that watch to see how it is being turned back on. It seems strange.
