Comfort Controller I/O Module (PCB2) — This input/output module is factory installed in the 50XJ unit and allows additional field points (8 inputs and 8 outputs): VFD (variable frequency drive) Bypass, VAV Terminals Control, Building Ventilation, and Heating Interlock.

Comfort Controller I/O Module (PCB3) — This accessory control input/output module can be ordered separate- ly and field-installed in the 50XJ unit. This module allows the addition of the following field-installed sensors: Tower Sump Temperature Sensor, Leaving Water Temperature Sensor, Building Pressure Sensor, CO2 Sensor, Indoor Relative Humidity Sensor, and Outdoor Temperature Sensor.

The accessory I/O module provides the following control outputs (relays): 4-stage heat control, water pump request, tower request, modulating exhaust fan, and external dehumidification.

Local Interface Display — The Local Interface Display (LID) is mounted on the front of the 50BV,XJ units. A number of user-adjustable features are entered/changed using the display keypad. These features described in detail in the Using the Local Interface Display section of this manual.

PCB Addresses — Switch 1 (SW1) is used to set each controller’s address. Individual DIP switches on each board are used to set the addresses for individual hardware points. PCB1 switches are factory-set for hardware points 1-15, PCB2 DIP switches are set for points 17-32, and PCB3 for points 33-48. For more information, refer to Table 1 and the Optional and Field-Installed Accessory Sensors/Devices section.

Control Module Communication — When power is applied to the OMNIZONE™ System Control panel, the red LED (light-emitting diode) 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. See Fig. 1. 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.

The yellow LED (the third LED from the bottom of the con- troller [PCB1]) will flash when the controller is broadcasting CCN messages to a laptop or other computer.
