Installed a Honeywell programmable thermostat. Problem is that it cycles on and off at least six times an hour, approximately 5 minutes on/ 5 minutes off. It's driving me crazy since the furnace for the second floor is in the attic, and it's loud. Went to the FAQ's at Honeywell and it states:
"cycle rate is the ideal number of times a heating system will run, in an hour, to maintain temperature within one degree. For instance, gas or oil forced air systems have a recommended cycle rate of 6. With a cycle rate of 6, the heating system, at a 50% load, will cycle 6 times per hour. This breaks down to about 5 minutes on and 5 minutes off. Again, the actual on and off time of the heating system will vary as the load on the heating system varies."
Is this true? Seems like a lot to me.
