Installation Notes

Heat Pump HVAC System Setup

System Type: Set the mechanical system type to Heat Pump in the Installer Settings Menu

Single Stage Compressor Systems use Y1 for stage 1 heating/cooling, and W1 for stage 2 Aux Heating.

Two Stage Compressor Systems use Y1 for stage 1, Y2 for stage 2 heating/cooling, and W1 for stage 3 Aux Heating.

Change Over Valve: You must configure the thermostat’s changeover valve setting to work correctly with your HVAC system. Check your system information to be sure.

Changeover settings are made in the Installer Settings – System Settings - Mechanical Settings menu.

Changeover with cool is the default setting and typical for most systems.

If you get cooling when you expect heating, change the C/O type to the opposite setting.

HVAC system transformer: Heat pump systems have one system transformer. Do not cut the RC/RH jumper. Wire the HVAC systems 24VAC common (blue wire) to the 24Com terminal, and the 24VAC return (red wire) to the 24RC terminal.
