Hello,
Here is my situation. The temperature has recently dropped and my furnace is back running (I was hoping I was done for the season). Anyways, the furnace cycles on and off too frequently.
I did some searching for the tolerance (hysteresis) on my thermostat and could not figure it out. So, I did some tests using another thermometer. I have the furnace set to 64 degF. I measured for ten on-off cycles and it looks like it is turning on ~63.7 degF and turning off ~64.2 degF. So there is only 0.5 degF tolerance.
What I am looking for is a new thermostat that has a looser (or even better adjustable) tolerance (hysteresis). I want to set it to 64 degF and have the furnace kick on ~61-62 degF and kick off ~64 degF ... give or take. I would like to have 2-3 degF between the on/off temperatures.
I would like to minimize the furnace cycles because the furnace is inefficient (80%) and it takes the furnace ~5 minutes from the time the furnace kicks on to where I feel warm air through the vents.
Any recommendation? And please not the obvious ... buy a higher efficiency furnace (unfortunately, not in the budget).
Thanks in advance.
