1. CHILLED WATER SYSTEM SHALL BE ENABLED WHENEVER A COIL IN THE SYSTEM CALLS FOR COOLING.

2. CHILLED WATER SYSTEM SHALL BE DISABLED WHEN NO COIL IN THE SYSTEM CALLS FOR COOLING.

B. CHILLED WATER PUMPS AND CHILLERS:

1. WHEN CHILLED WATER SYSTEM IS ENABLED, THE LEAD CHILLED WATER PUMP SHALL START AND RUN CONTINUOUSLY.

4 DESIGNATION OF LEAD-LAG SYSTEM PUMP: WHEN THE RUNTIME OF THE LEAD SYSTEM PUMP EXCEEDS THE RUNTIME OF THE LAG SYSTEM PUMP BY 150 HOURS (ADJ) AND THE LAG SYSTEM

BYPASS

PUMP IS NOT IN ALARM, THE DDC CONTROLLER SHALL DESIGNATE THE ENABLED SYSTEM PUMP AS LAG AND THE DISABLED SYSTEM PUMP AS LEAD. WHEN THE LEAD SYSTEM PUMP IS IN ALARM, THE DDC CONTROLLER SHALL DESIGNATE THE SYSTEM PUMP IN ALARM AS LAG AND THE SYSTEM PUMP NOT IN ALARM AS LEAD.

5. DDC PUMP CONTROLLERS SHALL INTERFACE WITH EACH ADJUSTABLE FREQUENCY DRIVE, STARTING AND STOPPING MOTOR AND BY TRANSMITTING A 4 TO 20 MA DC SIGNAL TO MODULATE PUMP

SPEED FROM MINIMUM TO FULL SPEED.

6. DDC CONTROLLER SHALL MODULATE LEAD PUMP SPEED TO MAINTAIN WATER PRESSURE SETTING AT DIFFERENTIAL PRESSURE SENSOR.

a. ON A DECREASE IN SYSTEM DIFFERENTIAL PRESSURE, LEAD PUMP SHALL MODULATE TOWARD FULL SPEED.

b. ON AN INCREASE IN SYSTEM PRESSURE THE REVERSE SHALL OCCUR, UNTIL THE FLOW REACHES MINIMUM FLOW OF THE CHILLER MANUFACTURER'S MINIMUM REQUIRED FLOW (ADJ) THROUGH THE EVAPORATOR. THE PUMP SHALL MAINTAIN CONSTANT SPEED AT THIS SETPOINT AND NOT MODULATE ANY LOWER.

6. WHEN LEAD PUMP IS AT MINIMUM SPEED, CONTROL VALVE BP-V SHALL MODULATE OPEN TO MAINTAIN SYSTEM DIFFERENTIAL PRESSURE.

a. ON AN INCREASE IN SYSTEM DIFFERENTIAL PRESSURE, CONTROL VALVE BP-V SHALL MODULATE TO FULL OPEN

b. ON A DECREASE IN SYSTEM PRESSURE, CONTROL VALVE V-1 SHALL MODULATE CLOSE. WHEN BP-V IS FULLY CLOSED, LEAD PUMP SPEED SHALL INCREASE TO MAINTAIN SYSTEM PRESSURE.

7. WHEN CHILLED WATER SYSTEM IS DISABLED, THE CHILLER SHALL BE TURNED OFF, AFTER THE CHILLER IS DISABLED, THE LEAD CHILLED WATER PUMP SHALL BE TURNED OFF.
