Strange behaviour with cooling of QHY268C: 100% cooling power and PLUS 10°C

Hi all,
on yesterdays sesson I observed a strange behaviour (Stellarmate 1.7.1):

I started my session, everything works fine. So I switched on cooling of my QHY268C down to -10°C. Cooler goes up to 100%, looked fine. But then I saw, that the temperature tryed to go UP to +10°C with always cooler at 100%! I changed target temperature to -8°C (and yes it was set to MINUS 10°C before) but still the same 100% cooler and about +10°C. I tried cooler on/off, but nothing changed. I disconnected the camera from INDI and reconnect: just the same behaviour. I had to physically disconnect the camera from the setup (remove voltage supply), afterwards it worked: -10°C at roughly 40% cooling power.
Now I remembering, that this was at least once the case after updating to 3.5.9, in the older versions I never saw this strange behaviour. I thought there was just a mistake in + and - but also at that time I was wondering that the cooler was at 100%!

Unfortunately I had the protocols not activated.

I have observed the same thing with a QHY600 running ekos/kstars on Ubuntu Linux. Restarting the driver from the control panel usually fixes it.
