1 "C" terminal connection
is not required on battery
powered, power stealing,
or some electromechanical
thermostats.
2 Leave jumper disconnected
for conventional thermostats.
This diagram shows the typical
three-stage equipment, thermostat,
and damper motor connections.
For specific wiring for other
thermostats, damper motors, and
HVAC Equipment, refer to the
Installation Instructions.

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.
