Hey guys, what can you tell me about thermostats? I have an old analog one that isn't functioning as it should, basically, if set on auto, the furnace fan runs at a slower speed and cycles on/off every few minutes, it's worst under high demand, like first thing in the morning when you increase the temp for daytime comfort. If you just turn the fan on, then it runs at full speed, no cycling and the house actually warms up.
Running a gas furnace with AC added to it. Current thermostat has 5 control wires, if that matters.
What I'm looking for is something that is simple and intuitive to use. A heat/cool switch, on/off switch, and a lever to control the temp is all that is needed. While it will be nigh impossible to find something that isn't an electronic atrocity, I just need the basics, I don't need ANY whistles or bells, and, I would prefer a name brand.
Any particular brand/models you can recommend?
