TZ-4 TOTALZONE® ZONE CONTROL PANEL
7 68-0259-1
.
Fig. 5. Heat pump thermostat with separate Y1 and W1
terminals and multi-stage thermostat wiring.
If the thermostat selected from Table 1 has 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
section for instructions on staging the TZ-4.
ARD or ZD Dampers
Wire the ARD or ZD Damper to the panel as shown in Fig. 8.
Multiple dampers can be wired in parallel. Use these dampers
on systems up to 2000 cfm.
AOBD Dampers
Wire the AOBD dampers to the panel as shown in Fig. 9. Two
AOBD can be wired in tandem as shown in Fig. 10. More than
two AOBD dampers require the Slave Damper Control Relay
(SDCR).
