A. CHILLER PLANT SYSTEM SCHEDULING

B. CHILLER SEQUENCING

C. COLOR GRAPHIC BASED CHILLER PLANT STATUS SCREENS

D. COLOR GRAPHIC BASED CHILLER STATUS SCREENS

E. SYSTEM AND CHILLER DIAGNOSTIC MESSAGES

F. SYSTEM AND CHILLER REPORTS

6. CHILLER SEQUENCING - THE CHILLER SEQUENCING SOFTWARE WILL START AND STOP SYSTEM WATER PUMP AND CHILLER BASED UPON

SYSTEM LOAD.

A. WHEN THE CHILLED WATER SYSTEM IS ENABLED, THE CHILLER SYSTEM CONTROL WILL START THE SYSTEM CHILLED WATER PUMP

AND PROVE FLOW THROUGH THE EVAPORATOR.

7. ADDITIONAL CHILLER SEQUENCING FOR VARIABLE PRIMARY FLOW CHILLED WATER SYSTEMS:

A. THE SYSTEM CHILLED WATER SUPPLY SETPOINT SHALL BE 42°F (ADJUSTABLE). ALTERNATIVELY, THE CHILLED WATER SUPPLY TEMPERATURE SETPOINT SHALL INCREASE UP TO 44°F MAX. WHEN THE AIR HANDLING UNIT CHILLED WATER CONTROL VALVE IS < 50% FOR 10 MINUTES (ADJUSTABLE). THE CHILLED WATER SUPPLY TEMPERATURE SETPOINT SHALL NOT EXCEED 44°F. IF THE AIR HANDLING UNIT CHILLED WATER CONTROL VALVE ≥ 50% OPEN FOR 10 MINUTES (ADJUSTABLE), THE CHILLED WATER SUPPLY

SETPOINT SHALL RETURN TO THE CHILLED WATER SETPOINT OF 42°F (ADJUSTABLE).

B. THE CHILLER SEQUENCING SOFTWARE SHALL STOP THE CHILLER WHENEVER THERE IS NO CHILLED WATER SYSTEM DEMAND FOR

30 MINUTES (ADJUSTABLE).

J. OPERATING MODE

K. CHILLER MODEL AND SERIAL NUMBER

L. CHILLED WATER CHILLER LOAD TRENDING: THE DDC SYSTEM SHALL CONTINUOUSLY MEASURE THE CHILLED WATER SUPPLY FLOW

RATE, AND THE CHWS AND CHWR TEMPERATURES, AND CALCULATE THE TOTAL BUILDING COOLING LOAD USING THE FORMULA

BELOW:

a. BUILDING LOAD (BTUH) = FLOW (GPM) X ((CHWS TEMP -CHWR TEMP) (DEG F) X 500).

DIAGNOSTICS/PROTECTION:

1. THE DDC SYSTEM SHALL BE ABLE TO ALARM FROM ALL SENSED POINTS AND DIAGNOSTIC ALARMS SENSED BY THE CHILLER

CONTROLLER.

A. ALARM LIMITS SHALL BE DESIGNATED FOR ALL SENSED POINTS.

B. SENSED DIAGNOSTIC POINTS SHALL INCLUDE THE FOLLOWING AT A MINIMUM:

C. SYSTEM CHILLED WATER SUPPLY TEMPERATURE

D. SYSTEM CHILLED WATER RETURN TEMPERATURE

CHILLER FREEZE PROTECTION:

1. WHEN OUTDOOR AIR TEMPERATURE IS 33 °F (ADJ.) OR BELOW THE CHILLED WATER PUMPS SHALL CYCLE AT MINIMUM FLOW AND THE HEAT TRACE SYSTEM SHALL ENERGIZE TO MAINTAIN WATER TEMPERATURE TO AVOID EVAPORATOR FREEZE. IF THE CHILLED WATER

TEMPERATURE FALLS BELOW 39 °F (ADJ.), AN ALARM SHALL BE SENT TO THE ECC.

PRIMARY VARIABLE SPEED CHILLED WATER CIRCULATION PUMPS STAGING CONTROL:

1. VARIABLE CHILLED WATER PUMP CONTROL: THE DDC SYSTEM SHALL CONTROL THE SPEED OF THE LEAD PRIMARY CHILLED WATER PUMP THROUGH THE VFD TO MAINTAIN 10 PSIG (ADJUSTABLE) DIFFERENTIAL PRESSURE AT THE DP TRANSMITTER LOCATED AT THE END OF THE CHILLED WATER LOOP. DP SETPOINT SHALL AUTOMATICALLY ADJUST TO MAINTAIN CHW VALVE POSITION (95% OF ALL CHILLED WATER VALVES SHALL BE LESS THAN 100% OPEN). UNDER NO CIRCUMSTANCE, HOWEVER, WILL THE VARIABLE FREQUENCY DRIVE APPLIED TO CHILLED WATER PUMP MOTOR BE ALLOWED TO EXCEED THE PUMP MOTOR FLA (FULL LOAD AMPS) AT ANY TIME. EACH VFD SHALL BE PROGRAMMED TO ACHIEVE THE FLA OF EACH MOTOR. ON A FAILURE OF THE PRIMARY PUMP DEDICATED TO A CHILLER, THE DDC SYSTEM SHALL AUTOMATICALLY SHUTDOWN ASSOCIATED CHILLER AND BRING ON THE NEXT SEQUENCED PUMP AND CHILLER AND SHALL CONTROL THE SPEED OF THE PUMP TO MAINTAIN THE DIFFERENTIAL PRESSURE AT THE END OF THE CHILLED WATER LOOP, AND

SEND AN ALARM OF THE FAILURE.

2. UNDER PROGRAM CONTROL, EACH CHILLED WATER PUMP VFD WILL BE AUTOMATICALLY STARTED AND STOPPED VIA A DDC COMMUNICATION BUS WITH AN ASSOCIATED DDC AO. A CURRENT SWITCH, INSTALLED AT EACH PUMP VFD, WILL PROVIDE ON/OFF

STATUS TO THE DDC AT ALL TIMES.

3. BASED UPON PUMP SPEED, PUMPS WILL BE STAGED ON AND OFF BY DDC TO ACCOMMODATE THE BUILDING FLOW RATE REQUIREMENTS UNDER THE FOLLOWING DDC OPERATIONAL SEQUENCES. UNDER AUTOMATIC CONTROL, SOFTWARE SUBROUTINES, USING "IF/THEN"

LOGIC STATEMENTS, WILL PROVIDE FOR "ON/OFF" STAGING AS DESCRIBED.

4. IF DDC SHOULD ATTEMPT TO AUTOMATICALLY START A PUMP AND THE ASSOCIATED SENSOR CAN NOT PROVIDE A SUCCESSFUL START, AN ALARM WILL BE ROUTED TO OPERATOR AT THE OWS (OPERATOR WORK STATION) INDICATING IMMEDIATE PUMP ATTENTION IS

NECESSARY AND THE NEXT OPERATIONAL SEQUENCE WILL THEN IMMEDIATELY BE ACTIVATED.

5. IF DDC SHOULD ATTEMPT TO AUTOMATICALLY STOP A PUMP AND THE ASSOCIATED CHILLER CAN NOT PROVIDE A SUCCESSFUL STOP, AN ALARM WILL BE ROUTED TO OPERATOR AT THE OWS INDICATING IMMEDIATE PUMP ATTENTION IS NECESSARY.
