Reset Operation

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by pressing all three (SYSTEM, and press both icons) simultaneously for 2 seconds.

This reset will restore your thermostat’s initial factory setting.

Remember to turn off your heating / cooling system BEFORE resetting your thermostat. You will then have to go through a full initial setup described in Part 3 and Part 4 of the manual before you can turn your Heating & Cooling system back on. Failure to follow this instruction may lead to your Heating & Cooling system damage or malfunction.
