Winter has hit Tulsa!
I have an Armstrong Air Ultra Tech 80 HVAC. No matter what I set the T-stat(Honeywell-mercury) to, the heat comes on at about 1-hr intervals.
i.g. set T-stat heat at 78-degrees and the actual room temp is 40-degrees; heat doesn't come on per T-stat reading, but will come on by itself in about 1-hr intervals. When heat comes on it warms up house only a few degrees (2-4) before it cuts off.
I've changed the T-stat to a digital one (Hunter) and still same result(I have triple checked everything with T-stat ~OK).
My conclusion is there must be a setting on the HVAC-unit itself. Is there something I can check, or is it time to call a Pro?
Please Help? Was a very cold weekend. Family is freezing arse off and wife is getting very grumpy!
THANK-YOU in advance!!!
