WIRING DIAGRAM NOTES

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

2.Refer to outdoor unit Installation Instructions for latent kit requirements.

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

4.Interface control transformer must be in phase with furnace transformer to get high-speed fan during heat pump operation.

5.Heat pump MUST have a high-pressure switch for dual-fuel applications.

6.Two-Zone Control does not know that dual fuel is applied. Do not use thermostat AUTO CHANGEOVER mode with dual-fuel applications, keep both thermostats in same mode (heating or cooling).

7.Configure Two-Zone Control board (jumpers) for:

(J1) T-stat = Fnc

(J3) Equipmt = HP

(J4) Fnc Ht = w/fan

(J5) LAT = Set LAT jumper high enough to allow furnace to come on during defrost and second-stage operation.

(J7) DTO = On

8.Furnace must control its own second-stage heat operation, via the furnace control algorithm.

9.Refer to outdoor equipment Installation Instructions for proper set up.

10.Select Furnace Interface option, Balance Point, and Defrost Time on 2-speed heat pump control board.

11.DO NOT select "ZONE" position on 2-speed heat pump control board. In heating mode, heat pump outdoor temperature sensor will control the compressor low- and high-speed change.
