    I have a heat pump and furnace combo. The heat pump works extremely well down to around -10C. Below that it takes a very long time to move the needle by half a degree. The furnace doesn’t kick in until the thermostat sees the house temperature trending in the opposite direction it’s attempting to achieve.

    Unfortunately, its method of determining the time gradient of temperature is rather moronic and doesn’t take the temperature schedule into account. This means every morning when the schedule calls for higher daytime temperatures (even by just half a degree) the thermostat freaks out thinking that the house is cooling rapidly and kicks on the furnace to bring up the temperature.

    This causes the system to needlessly run the furnace every single morning. It annoys the hell out of me but I don’t know what to do about it. Aftermarket thermostats aren’t very common around here (Canada).

      Have you checked home automation forums? Some users are fanatics about tweaking stuff. Maybe there is a method or override option. Or see if you can get manufacturer on the phone.

        My issue is home insurance and HVAC regulation in Canada. I don’t know what is legal and what isn’t as far as HVAC system modifications go, given that I’m not a licensed HVAC technician. Doing my own home automation mods badly could damage or destroy either my heat pump or furnace, resulting in thousands of dollars in repair bills. Or it could jeopardize my home insurance in case of a fire and result in even greater financial losses, even if my modifications were only tangentially related to the cause of the fire.

          Understood, the manufacturer may have a firmware update to solve the issue you mentioned

            That’s a good point. I should look into that. It does have the ability to connect to the thermostat with an app but I never tried that.

      There are a variety of aftermarket thermostats available at Canadian Tire, many of which are quite good. The Home Automation enthusiasts seem to be big fans of ecobee, IIRC, and I have seen ecobee thermostats at CT.
