WIRING DIAGRAM NOTES:

1.Furnace must control its own second-stage heat operation via furnace control algorithm. Refer to indoor equipment Installation Intructions for proper setup.

2.See Option 5 information to convert HP thermostats to AC thermostat operation.

3.As an option, lock the furnace into low-heat operation and let O/B control high-heat operation. Refer to indoor equipment Installation Instructions for proper setup.

4.O/B can control second-stage heat. Refer to indoor equipment Installation Instructions for proper setup.

5.Refer to outdoor equipment Installation Instructions for latent kit requirements (if any).

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

7.O/B energizes reversing valve in cooling or heating. See Option 10.

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

9.If system is wired per diagram, the ACRDJ (jumper) on furnace control board should be removed to allow thermostat to control outdoor unit staging.

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