Heat Pump Equipment

Wire the heat pump to the equipment terminals on the panel
as shown in Fig. 15. Refer to manufacturer’s instructions for
additional wiring instructions and substitute the TZ-3
equipment terminals for the thermostat terminals shown.

Trane) use the B terminal as the transformer com-
mon. Do not connect the common from the equip-
ment to the zone control panel.

Two-speed Compressor: Wire the second stage compressor
to both Y2 and W2. Wire the auxiliary heat to W3. Remove the
two-stage emergency heat jumper and install a jumper from
W3 to E.

Fig.15 but use the manufacturer’s fossil fuel kit. Wire the
Trane XL 1800 and the TAYPLUS 103 as shown in Fig. 16.
The recommended thermostat is theT8611G2051.
