I have 2 gas furnaces in my home. Upstairs and Downstairs. Both hooked up to a Wyze thermostat. Upstairs works perfectly. Downstairs however has a problem. When the outside temp drops below 60 and my heater is supposed to heat to 73 (yes, we like it warm), it never seems to get there. It keeps saying “heating to 73 in 8 minutes” and and 8 minutes later: “heating to 73 in 30 minutes. the temp stays at 70 or 71 during that time.
I changed airfilters, checked the furnace and all seems to be working good. Set the wyze preference to max comfort and schedule is set for 73 around the clock.
Anyone have this issue? and fixed it?
