Question about Honeywell Programmable Thermostat Heater
When we put the thermostat to heat, it only blows cool air. However when we set the thermostate to EMT HEAT, the warm air DOES blow out. What does EMT Heat switch mean and what is the difference between it and the regular heat switch? Why does one blow out heat and the other does not??
Any thermostat that connects to anything independent can be difficult to troubleshoot. Not only do you have to check that unit for trouble, you have to make sure it's not getting a strange signal from elsewhere. I really love the convenience of home automation but it can create a network of issues. Best to call customer support so their techs can troubleshoot it.

On heat pumps, the normal setting is simply an air conditioner working in reverse. The EMT or AUX heat is a supplemental heating system using electric heating elements instead of the hermetic (compressor) system. As far as why the regular heat does not work it can be one of many things. low freon charge. reversing valve not functioning. The defrost cycle not working. Take your pick. you may want to call a service man to repair it as the electric (EMT) is not as efficient.

Many thermostats have battery backup as well as the 24 volt ac. Have you replaced the batteries to see if it fixes all of your issues at once?

Sounds like you have a T86 thermostat...take the round front cover off to view the Mercury switch. Watch the bulb when you change the temperature to a higher setpoint. If the bulb makes contact when rotating it up, and the furnace doesn't go into a call for heat, then it could be the thermostat, wiring, or furnace problem.
