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 buttons (TIME, and both buttons) simultaneously. 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.
