It sounds to me like you have a bad thermostat wire. The brains to the coal trol is in the thermostat, and when pulling the wire thro the walls they sometimes break and will not send signals to the power mod. I can send you another wire, but it will not go out till Monday's UPS. If you can't wait, you can pick it up at Wal-mart or Radio shack. It's 8 straind wire, round or flat will work. Please let me know.
