I have had Nest thermostat for a long time and it always functionned well even at extremes temperatures. My Thermopump and auxiliary furnace were changed recently. My new thermopump is working down to -24 Celsius ( my old one was working down to -15)...

I still do not have the answer. The inferior limit to pass from thermopump to AUX NEST thermostat is -12 Celsius. The new thermopumps can work as bellow -20 Celsius. So below -12, my system uses AUX even if my thermopump could do the job done to -20....
