WIRING DIAGRAM NOTES

1. The AC model thermostat can only control 1-stage cool and 1-stage heat. Dip Switch-C on has no controlling function and can either be

ON or OFF.

2. HP and 2S model thermostat MUST have Dip Switch-C ON when installed in air conditioner applications. If required, second-stage heat

is controlled by O/W2. Refer to indoor equipment Installation Instructions for proper setup.

3. HP and 2S model thermostat MUST have Dip Switch-C OFF when installed in heat pump applications. The reversing valve is controlled

by O/W2.

4. Intelligent Heat Staging Option: 2S model thermostat with Dip Switch-C OFF and Switch-D ON. This provides single-stage heat pump

operation Y/Y2, with three-stage auxiliary heat via W/W1 and Y1/W2. Refer to variable-speed fan coil Installation Instructions. Proper
’intelligent heat capable’ electric heater package must be used.

5. As an option, lock the furnace into low-fire operation and let O/W2 control high-fire operation. Refer to indoor equipment Installation

Instructions for proper setup.

6. Furnace must control its own second-stage heat operation via furnace control algorithm. Refer to indoor equipment Installation Instructions

for proper setup.

7. Terminals marked with * may not be present on equipment.

8. Refer to fan coil Installation Instructions for proper wiring.

9. Select the "ZONE" position on the 2-speed heat pump control board.

10. Omit red and pink wires from diagram with wiring a 564A or 664A with 2-stage heaters.

11. Refer to outdoor equipment Installation Instructions for proper setup.

12. Program thermostat to bring on G (fan) with any W (heat) selection. See section under "set thermostat configuration."
