Question about Heating & Cooling
Old, analog thermostat. Once or twice a month we have morning events in the otherwise unheated space, and need a timer, or a new, cheap, simple thermostat to turn the heat on at around 4am, and doing that by hand gets old really fast. We don't need anything with multiple program options, and really don't need anything connected to a phone.

On your thermostat - R is the power in terminal. Y is the cooling out. W is the heating out. (G is fan out). It does not matter which wire goes to R, the other should go to W - if no heat with a call, the thermostat is bad.

if you cross the two wires and you see a slight spark and heat comes on, then the problem is in the thermostat, if not then problem is at furnace it self.

You need a specific thermostat for a Wall Furnace it is a Millivolt Thermostat and not a 24v standard thermostat....usually it will work anyway however if the powerpile (generator produces millivolts from the pilot light) is weak it may not be producing enough...or the Pilot light may be dirty and lazy...won't produce enough millivolts ...or you can have bad or dirty contacts or connections....or a combination of any of the above.....a 24v Thermostat and particularly a non-mercury thermostat has too much resistance in it for a millivolt system....as your Wall Furnace (other than the fan) runs on less than 1 volt
