My simple comfort 2200 thermostat has a brown wire hooked to the e terminal. what is the e terminal for?


Likely for emergency heat. When the heat pump is in defrost mode, due to extremely low ambient temps, e is your indoor heat strips.

I can't find that model, but when you set it where you want it, does it have a hold button? If so, press hold after setting temp.

Where do I set thermostat when temp is 10 degrees outside?


Setting a thermostat has nothing to do with outdoor temperature, but more to do with what is a comfortable setting for you and your utility bill.

A common misconception associated with thermostats is that a furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings. This misconception has been dispelled by years of research and numerous studies. The fuel required to reheat a building to a comfortable temperature is roughly equal to the fuel saved as the building drops to the lower temperature. You save fuel between the time that the temperature stabilizes at the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

Another misconception is that the higher you raise a thermostat, the more heat the furnace will put out, or that the house will warm up faster if the thermostat is raised higher. Furnaces put out the same amount of heat no matter how high the thermostat is set; the variable is how long it must stay on to reach the set temperature.

In the winter, significant savings can be obtained by manually or automatically reducing your thermostat's temperature setting for as little as four hours per day. These savings can be attributed to a building's heat loss in the winter, which depends greatly on the difference between the inside and outside temperatures. For example, if you set the temperature back on your thermostat for an entire night, your energy savings will be substantial. By turning your thermostat back 10 to 15 degrees for 8 hours, you can save about 5 to 15 percent a year on your heating bill -- a savings of as much as 1 percent for each degree if the setback period is eight hours long.
Hope this helps..........

Heat will not work. just blowes cold air


Few things it could be.
The heat strip itself, the Bi-metal (Heat sensor safety) or the Power that feeds it from the Thermostat. Also there is the Fuse link that is built into most strips.
If you have a voltage meter there are a few simple ways to check the operation.
If your not comfortable to check these I would recommend having a local Hvac company service the heat, It's better to be safe then sorry in case there is a electrical problem with the unit.

Good Luck!
