I have a heat pump with a gaz furnace. My Nest thermostats learning is set to Dual Fuel. My lockout temperature is -12c. So when it under -12c just the gaz will be use.
My Question is: Over -12c, how the thermostats will manage the heat stage? Is it just, over -12c just use the heat pum and under -12c just use the gaz.
or
Under -12c just use the gaz
Over -12c use both but it will follow a algotyhme following time to heat
Thanks!

Hi NickP1,
Thanks for reaching out. If your Nest Thermostat's Heat Pump Balance is off, your thermostat will use your AUX heat based on a lockout temperature that you set. If you set it to -12 C, your gas furnace with turn on when the temperature goes below -12 C.

My set up is dual fuel.. So the option of the heat balance is deactivated. Is there a another possibility to activate the heat balance with a heat pump + gaz furnace?

Hi NickP1,
Thanks for the response. I'm sorry for the confusion. You're correct. The Heat Pump Balance feature is only available for heat pumps with AUX heat. With the type of system that you have, we would need to use a lock out temperature. I understand that having an option to use the Heat Pump Balance feature on dual fuel system would be helpful. Our team is always looking for ways to improve and we'll take this as feedback.
Thanks,
Edward
