22.The control forces CMP4 (compressor 4) on, if config- ured, then waits 5 seconds.

The LID display shows: Factory/Field Test Stop

The yellow LED will go off, and the red LED will go off.

23.The control forces CMP4 off.

24.The run test is complete.

Power Up the LID Display — After completing the automatic run test, perform the following procedures to change the controller password, set the controller clock, configure schedules, set parameters, view settings, and view alarm history.

1.Set the Remote/Local/Off switch on the front of the unit to the OFF position. This prevents operation of the fan and compressors while still providing power to the unit controls.

NOTE: When the switch is in the OFF position, the red alarm LED will be lit; this is normal. The bypass point will also indicate OK.

2.If the unit access panel (for power and controls) is still on the unit, remove it in order to view the control modules during start-up.

3.Switch the main unit power disconnect to ON.

When power is applied to the OMNIZONE™ System Control panel, the red LED on the top front of the processor module will flash at a rapid pace (about twice a second) for the first 30 to 60 seconds. This rapid flash will then be replaced by a slower paced flash (about once per second).

The green LED below the red LED will start flashing. This LED indicates input/output communications for accessory input output modules and the LID display.

The yellow LED will flash when the controller is broadcast- ing CCN messages to a laptop or other computer.

The third LED from the bottom of the controller (PCB1) will light.

The LID display will show the controller identification, time and date as shown below.

OMNIZONE VPAC hh:mm mm-dd-yy
