Had mine changed over last aug. works great, that is until last few days the temps drop so switched on the heat. Guess what? Now the ccc unit is so sensitive it cycles the heat every few minutes. set for 70 it comes on at 69 and goes off at 70. Yikes so now what?.
I mean it keeps the unit heated fine just that on off on off, runs few minutes (3 or 4) off 3 or 4) Any Ideas out there? Cooling if set at 73 it came on a 75 off at 72, 4 deg spread not like on heat where it is 1 deg spread.

The most common cause of this, is placement of the thermostat relative to the floor vents. A simple test can be performed by covering up the vents located nearest the thermostat. If the problem goes away, you have the answer. You can add a defelctor to the vent to steer the hot air away from the thermostat.
