STARTUP AND CHECKOUT
After the installation is complete, verify correct operation as
follows:
1. Place the Em Heat switch in the Off (down) position.
2. Place the Zone-A-Lone switch in the Occup/Remote
(up) position.
3. Verify that the DIP switches are set correctly. See
Sequence of Operation section and Table 6 for correct
configuration.
4. Power up the TZ-3 and set the thermostats so no zones
are calling. The board then enters the Purge mode
where all dampers open and the fan operates for two or
three and one-half minutes (configurable). (If there is
no Discharge Air Temperature Sensor connected to the
panel, the Idle LED flashes seven times before entering
the Purge mode.) Then the Idle LED turns red and each
damper LED turns green.
5. Set zone one thermostat to heat and raise the setpoint
to call for heat. Verify that the heat LED is red and zone
one damper remains green while the other damper LED
turns red.
6. Raise zone two setpoint to call for heat. Lower zone one
setpoint to stop the call for heat to that zone. Verify that
zone one LED turns red (it may be amber while moving)
and zone two LED turns green.
7. Repeat for zone three.
8. Alternately, lower the setpoint to call for cooling.Verify
that the green cool LED illuminates.
