So I'm sitting in 50 degree cold and want to turn my heater on for the first time, but the thermostat does not have a heater option. It only has Cool, Fan and Dry. It's a 2022 Transcend, 240ML. Any help is appreciated
Sounds like you are looking at an air conditioner control, not your propane fired main heater thermostat. or you need to keep pushing the mode button until you get to the the heater controls.
