I have an old natural gas central unit. It is heat only and is old enough that is uses a mechanical fan control switch. I only use it, in place of my heatpump, when temps are in the 20s.
It works beaautifully--maybe to good.
I am using a new Honeywell Pro TH311OD and when the outdoor temp is in the twenties or teens, the house stays at a constant 69 degrees.
The gas unit cuts on a runs only about 3-5 minutes and cuts off.
I am not complaining but seems to me like the temp in the home should drop a degree or two before calling for heat.
I have looked at the instructions and I don't see a "heat anticipator" adjustment as it is electronic and non-programmable.
Should I just be happy and deal with the short cycling?
