A: Photos of existing control points have been provided. There are (22) identified control points for each CRAC unit. There are (2) pairs of low voltage control wires and (1) RS485 control wire for each CRAC unit, along with the smoke detector.

Each CRAC unit communicates the following back to our DDC Controls Shop:

System Status, RA Temp, RA Temp Set-Point, RA Temp Deadband, RA %RH, %RH Set-Point, %RH Deadband, CHW Valve Position, Heating Stages On, Dehumidification Status, Humidifier Status, High Temp Alarm, Low Temp Alarm, High Humidity Alarm, Low Humidity Alarm, Blower Fan Status, Blower Fan Alarm, Filter Status, Water Under Floor Alarm, FireStat Alarm, Maintenance Due Notification.

Note 2: The intent of the project is to re-use existing Controls equipment and programming. Existing wiring includes (1 to 2) RS485 COM cables per CRAC unit, and (2) Pairs of 24V DC Control wires per CRAC unit. These wires come through a junction box on the near wall to each unit and back to the Mechanical Room to an ENC-520-2 Main Controller. The intent is to re-use all existing wiring to connect to the NEW CRAC units. If the location of the connection points to the New CRAC units requires longer control wires, the 24V DC wires should be able to be spliced and lengthened from the junction box. The RS485 COM wires may require a new continuous length.
