Fig. 16. Wiring conventional heating and cooling equipment to TZ-4 panel.
Heat Pump Equipment
See Fig. 17-22 for heat pump wiring. Refer to manufacturer
instructions for additional wiring details and substitute the
TZ-4 equipment terminals for the thermostat terminals shown.
Connect the changeover relay to O/B equipment terminal.
Set switch number 5-7 to on for O (cool) changeover, or to
off for B (heat) changeover.
Set switch number 5-1 to off for heat pump equipment.
Set DIP switches 4-1, 4-2, 4-3, and 4-4. See Single Stage
and Multi-Stage Operation in the Operation section.
IMPORTANT
Some heat pump manufacturers (such as York and
Trane) use the B terminal as the transformer
common. Do not connect the common from the
equipment to the zone control panel.
Single-Speed Compressor: Wire the compressor to the Y1
terminal.
If the same heat source is used for auxiliary heat and
emergency heat:
Wire a jumper from W2 (auxiliary heat) to W1/E
(emergency heat).
Do not connect W3/AUX. See Fig. 17.
If auxiliary heat is separate from emergency heat:
Connect the auxiliary heat to W2 jumped to W3/AUX.
Connect the emergency heat to W1/E. See Fig. 18.
