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.

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.
