Hi, I'm Douglas and I am here to help you resolve problems with your heating and cooling equipment.

You can try to change the cycle rates in the thermostat.

1. Put the selector switch to off.
2. Adjust the thermostat down to 52 degrees
3. As soon as it shows the room temperature (about 5 seconds) press and hold both up and down simoultaniously for about 3 seconds and release to get into the set up mode.
4. Press the set button within 5 seconds to get to the cycle rate (CPH)
5 using the up or down arrow change the cycle rate to 3
6. Press Set to scroll through to END and then put the switch back to heat mode.

This will lower the number of cycles per hour giving you longer runs and longer off cycles.

Not easy, but I will try this suggestion!

Easier than moving the thermostat, is it not?

Do you want a hard copy of these instructions for your records?

Its starts on the bottom of page 6 under customizing your thermostat and continues on page 7.

The only other recomendation I have is to make sure the hole in the wall behind the thermostat is sealed up.
