TEST, CHECK AND START-UP
1. Verify that all component wires have been connected to the proper terminals and are secure.
2. Make sure that the selector switches on the panel are in their proper position for the specific
equipment application.
3. Temporarily disconnect the R wire from the panel to the HVAC system.
4. Apply 24 Volt power to the panel.
5. Place all zone thermostats in the OFF mode with Auto Fan.
6. With no calls taking place, the following panel LEDs should be lit:
PWR
ZD1
ZD2
ZD3
ZD4
DAS (If Discharge Air Sensor is wired to panel)
OTS (If Outdoor Temperature Sensor is wired to panel)
7. Visually confirm that all zone dampers are in the open-position.
8. Place zone 1 thermostat in the continuous fan ON mode. The following LEDs should be lit:
PWR
ZD1
DAS (If Discharge Air Sensor is wired to panel)
OTS (If Outdoor Temperature Sensor is wired to panel)
G
9. Put zone 1 thermostat in Auto Fan and repeat the same steps for each zone thermostat in the
system. The only change in LED status will be the ZD2 LED will light for zone 2, ZD3 LED will light for
zone 3 and ZD4 will light for zone 4.
10. Once the ventilation test is completed, and the zone thermostat fan modes are set to Auto, place
zone 1 thermostat in the cooling mode and adjust the setpoint above the space temperature until it
calls for cooling. Keep in mind that the zone thermostat may have a time delay.
NOTE
: The panel also has built-in time delays that can be put in speed up mode
by pressing the SPD UP button on the panel. The SPD UP LED will start blinking
confirming the time delays in the panel are in speed up mode.
3 seconds = 1minute in speed up mode. Pushing the SPD Up button manually
turns speed up on and off. If left on, speed up mode will automatically drop out
in 10 minutes.
