TEMPERATURE CONTROL SEQUENCE

A. GENERAL: Temperature control work shall be performed by the building controls contractor

Johnson Controls Inc. Modify the existing DDC system as required to provide the specified sequence of control. Provide all sensors, switches, relays, electrical wiring , panels, and programming etc. required for a complete operating system. Submit shop drawings with temperature control wiring diagram, points list, and sequences of control.

B. Sequence of Control - CH-4:

1. CHILLER CH-4 is an air cooled chiller to be used in shoulder seasons to generate chilled water for building cooling.

2. START UP: When enabled through the DDC system based on operator selection, the chiller iso;ation valve shall open and the designated lead primary chilled water pump shall ramp to the set speed through the pump VFD and run continuously to maintain 530 GPM

(differential pressure of 4.5 psig) through the chiller evaporator. Once flow status has been confirmed (DI point) chiller CH-4 shall be enabled.

3. Chilled Water Temperature Control: Once enabled the chiller leaving water temperature shall be controlled through the internal chiller controls to maintain a leaving water temperature of 45 degrees F.

4. The existing chiller sequences for CH-1, 2 and 3 shall remain as programmed.

C. BAS Shall Generate the Following Alarms:

· Loss of CH-4 status is detected

· Loss of chilled water flow through the evaporator is detected

· Any chiller fault is detected.

D. Minimum Points List: Provide the following minimum points for chiller CH-4 as well as additional points required to provide the above sequence of control:

· CH-4 chiller enable (BO)

· CH-4 chiller status (BI)

· Chiller staging (AO)

· Chiller evaporator differential pressure (AI)

· Chiller evaporator water isolation valve (BO)

· Chiller chilled water supply temperature (AI)

· Chiller chilled water return temperature (AI)

· Pumps P-1, P-2, and P-3 speed (AO)
