Thermostat Setup:

Heat Pump HVAC Systems

To set the HVAC system type, go to the Main Menu

Thermostat Info screen and press and hold the Setup button.

1. Type. Set the HVAC System Type: set to Heat Pump

2. C/O type. Change Over (reversing) Valve Type. Heat pumps change from heating to cooling by reversing operation.

You must configure the thermostat's changeover valve setting to work correctly with your HVAC system.

Check your system information to be sure and note the color of original thermostat wire and the terminal it was connected to.

No matter what the old stat connection was (O or B), connect the wire to the thermostats W2/O terminal.

The setting of the C/O Type will set the correct system operation.

For change over with cool systems (Orange wire, O terminal): set C/O type to w/cool (most common and default setting)

For change over with heat systems (Brown wire, B terminal): set C/O type to w/heat

3. 2nd Stage Heat. Enable second stage heating outputs

If you have a single stage heating system, leave this set to N

If you have a 2 stage heating system, set to Y to enable.

4. Aux Heat (HP). If you have auxiliary heat strips, set this to Y to enable.

5. 2nd Stage Cool. Enable second stage cooling outputs

If you have a single stage cooling system, leave this set to N.

If you have a two stage cooling system, set to Y to enable.
