Hi,
If the thermostat is not over shooting the temperature than don't worry about it.
These thermostats are very sensitive and will turn the heat back on even before the degrees drop on the display. Often they will shut down before the display changes also. You can change the sensitivity of the thermpstat if you read the directions and change the cycles per hour to a less number. There is an installers program in there that you need to push a combiunation of buttons to get too. The instructions tell you how to do that also.

Hopefully you did not throw away the instruction manual for your t-stat.. :-)

Welcome to Fixya.

This error code implies "heating or cooling equipment missing"- on easier terms, something might be disconnected or incomplete as you may not have everything hooked up. If so, you need to go to the installer menu to make sure you have the correct settings.

Here's a user's manual just in case :
