Fig. 19. EMM-3U with Air Conditioning Zoned with Dampers and Hydronic Heat Using V8043 Zone Valves.

STARTUP AND CHECKOUT

After the installation is complete, verify correct operation:
1. Place the Em Ht switch in the Off (down) position.
2. Verify that DIP switches are set correctly.
3. Turn on power to the EMM-3U Panel and set the ther-
mostats so no zones are calling.
a. EMM-3U enters the Purge Mode, opening all damp-
ers and operating the fan for two or three and one-
half minutes (configurable). In Purge, damper LEDs
are green to indicate the dampers are open.
NOTE: If a Discharge Air Temperature Sensor is not con-
nected to the panel, the purge LED flashes in all
modes other than Purge.
b. Press the Purge Override button on the panel to exit
the Purge mode early.
4. Set the zone one thermostat to heat and raise the set-
point to call for heat.

setpoint to stop the call for heat to that zone.
7. Verify that zone one LED turns off and zone two LED
turns green.
8. Repeat for zones two and three.
9. Alternately, set the System switch to Cool, and lower the
setpoint to call for cooling.
