ccd_simultor: coolding does not work

[rumengb]

turn on cooling set target temperate and nothing happens.

It does work :) Temperature is decreased or increased 1 degree every 5 seconds/

[rumengb]

It just does not work sometimes. I waited for several minutes. Then reloaded the diver.

It is not only the cooler. When i start guiding with guider imager, start exposures with imager and turn the temperature control on. very often it never starts, sometimes guider freezes like in the example below:

And the exposure becomes busy... and stays like that forever:

[rumengb]

it is not new.... it affects 2.0-128 too on both rpi and intel.

The issue is introduced with 2.0-126. it does not happen with 2.0-124.
