Why does the thermostat say heat is on when the heater is not running?
The cause could involve the thermostat, wiring, controls, equipment, or a safety condition. Testing is needed to determine where operation stops.
Can I use a smart thermostat with my heater?
Compatibility depends on the equipment, wiring, stages, accessories, and power requirements. These should be confirmed before installation.
Can thermostat placement affect heating comfort?
Yes. Sunlight, drafts, walls, nearby supply air, and room location can cause the thermostat to sense conditions that do not represent the rest of the home.
