How do I reset my thermostat?

If your thermostat is behaving erratically or something strange is in the display, hitting “Reset” buttons can often correct the problem.

Hardware Reset:

Try this first since it does not erase anything.  Take the front of the thermostat off the wall and look for a small black round reset buttons labeled “HW RST”   Hold this button down for at least 5 seconds.  The screen should fully populate temporarily.

If this does not correct the problem, proceed to a Software Reset

Software Reset:

These steps will erase your custom program settings, so write down all temperatures and start times before you begin.

Look for a small black round reset button labeled “SW RST”   Hold this button down for at least 5 seconds.  The screen should fully populate temporarily.

The day & time will still be correct, but you will have to enter back in all your custom program values.

Place thermostat front cover back on the wall.
