terminals and multi-stage thermostat wiring.
If the thermostat selected from Table 1has a single Y terminal
for first stage heat and cool, wire as shown in Fig. 6. Wire
either O or B (not both) from the thermostat to the O/B
terminal on the panel. Locate the O/B thermostat jumper on
the TZ-4 near each zone thermostat wiring terminal. Connect
the jumper if O was used or leave disconnected if B was used.
Connect second stage, auxiliary heat to W2.
When using two- or three-stage heat pump thermostats with
single Y first-stage hookup, place a jumper from W2 to Y2 on
the TZ-4 thermostat connections. See Fig. 7.
See Single and Multi-Stage Operation in the Operation
