I have a honeywell T8400C1024 digital manual thermostat and a mid-efficiency forced air furnace. They installation manual for the thermostat says the anticipator setting should be 6 which corresponds to
6 cycles per hour and .6 amp current for the 24 ts circuit. I admit this keeps the hour at a very comfortable consistent temperature. When the temp outside is -30 I have no problems with how it's functioning. Now when it's about freezing outside the furnace still runs 6 times per hour, but it only runs for a minute at a time. This seems like it must be rather inefficient. Any comments on energy efficiency? I've thought about turning the anticipator to 3, but I'm worried about damaging it. Also when it is very cold out it would definitely be less comfortable in the house. Thanks,- posted
