Thermostat Setup:
Heat Pump HVAC Systems
To set the HVAC system type, go to the SYSTEM menu.
1. SYSTYPE: Set the HVAC System Type: set to HP (Heat Pump)
2. FANTYPE: Automatically set for heat pump systems. Ignore this setting.
3. CO: Changeover (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 CO Type will set the correct system operation.
For changeover with cooling systems (Orange wire): set to C (cool: most common and default setting)
For changeover with heating systems (Brown wire): set to H (heat)
Go to ADVANCED SYSTEMS SETTINGS to set the following:
4. AUXHEAT: If you have auxiliary heat strips, set this to Y to enable.
5. 2ND HT: Enable second stage heating outputs
If a single stage heating system, leave this set to N
If a 2 stage heating system, set to Y to enable.
6. 2ND CO:. Enable second stage cooling outputs
If a single stage cooling system, leave this set to N.
If a two stage cooling system, set to Y to enable.
