Before operating the system, you must configure the thermostat for the correct HVAC system type. You will need to
know the following information to correctly configure the thermostat. The HVAC setup is in the
Mechanical Settings
menu screen.
HVAC system type
: What type HVAC system do you have? Standard or Heat pump
For Standard systems
: Fan Type: Do you have Gas heat or Electric heat?
For Heat Pump systems
: Change over valve (or reversing valve) type: Does your system change over with cooling
operation or with heating operation? Check your existing thermostat connects to help determine this. If the original
system had an orange wire connected to an “O” terminal, then you have a “changeover with cool” system. If you have a
brown wire connected to the “B” terminal, then you have a “change over with heat” system.
