Drawing M-702 – CONTROL DIAGRAMS 2

1. Replace the Sequence of Operation – Chilled Water System in its entirety with the following:

WHEN A CHILLER IS ENABLED, THE FOLLOWING SHALL HAPPEN IN THIS ORDER: THE CHILLER'S

INTERNAL ISOLATION VALVE SHALL OPEN, ITS ASSOCIATED INJECTION PUMP SHALL START.

AND ONCE FLOW IS PROVEN BY THE (INTERNAL) FLOW SWITCH, THE CHILLER SHALL BE

COMMANDED ON TO OPERATE UNDER ITS PACKAGED CONTROLS.

WHEN A CHILLER IS DISABLED, THE FOLLOWING SHALL HAPPEN IN THIS ORDER: THE CHILLER

SHALL STOP, THE INJECTION PUMP SHALL STOP, AND THE CHILLER'S INTERNAL ISOLATION

VALVE SHALL SHUT.

WHENEVER THE CHILLED WATER SUPPLY TEMPERATURE (CHWST) RISES MORE THAN 2°F

(ADJUSTABLE) ABOVE THE CHILLED WATER SUPPLY SET POINT (CHWSP) FOR MORE THAN 5

MINUTES (ADJUSTABLE), THE LAG CHILLER SHALL BE ENABLED. WHEN THE CHWST IS AT OR

BELOW THE CHWSP FOR MORE THAN 2 MINUTES (ADJUSTABLE), AND ALL CHW VALVES ARE

BELOW 50% OPEN, THE LAG CHILLER SHALL BE DISABLED.

THE CHWSP SHALL BE 2ºF (ADJUSTABLE) HIGHER THAN THE CHILLER DISCHARGE WATER SET

POINT (CHDWSP). THE CHDWSP SHALL BE RESET IN THE CHILLER MANUFACTURER'S CONTROL

PANEL VIA BACNET ACCORDING TO BUILDING COOLING DEMAND AS DETERMINED BY THE

COOLING COIL CONTROL VALVE THAT IS THE MOST OPEN.

THE CHDWSP SHALL BE RESET LINEARLY ACCORDING TO THE FOLLOWING USER-ADJUSTABLE

RESET SCHEDULE:

MAXIMUM VALVE POSITION CHILLER DISCHARGE SET POINT (CHDWSP)

90% OPEN 42ºF

50% OPEN 48ºF

WHEN ALL THE CHW VALVES ARE MORE THAN 90% OPEN AND THE CHWST REMAINS 2ºF

(ADJUSTABLE) ABOVE THE CHWSP FOR MORE THAN 30-MINUTES (ADJUSTABLE), THEN THE

PRIORITY VALVE SHALL CLOSE, AND CHILLED WATER LOOP PUMP (P-4 OR P-5) SHALL RUN AT

FULL SPEED. ONCE ALL CHW VALVES ARE LESS THAN 50% OPEN FOR MORE THAN 30- MINUTES

(ADJUSTABLE), THE PRIORITY VALVE SHALL OPEN, THE CHWDSP SHALL RETURN TO THE RESET

SCHEDULE VALUE, AND THE CHILLED WATER LOOP PUMP (P-4 OR P-5) SHALL RETURN TO

NORMAL OPERATION.

THE CHILLED WATER LOOP PUMPS (P-4 AND P-5) SHALL OPERATE CONTINUOUSLY IN A

LEAD/LAG ARRANGEMENT WHENEVER THE CHILLED WATER SYSTEM IS ENABLED. IF THE LEAD

PUMP FAILS TO SHOW PROOF OF FLOW OR THE LEAD PUMP VARIABLE FREQUENCY DRIVE (VFD)

INDICATES AN ALARM CONDITION, THE LEAD PUMP SHALL STOP AND THE LAG PUMP SHALL

AUTOMATICALLY START.

THE LEAD PUMP (P-4 OR P-5) SPEED SHALL MODULATE TO MAINTAIN THE CHILLED WATER

SYSTEM DIFFERENTIAL PRESSURE SET POINT OF 15 PSI (ADJUSTABLE). THE PUMPS SHALL NOT

OPERATE BELOW MINIMUM SPEED (DETERMINED BY THE PUMP AND VFD MANUFACTURER).

CHILLED WATER SUPPLY AND RETURN TEMPERATURES SHALL BE USED IN CONJUNCTION WITH

CHILLED WATER SUPPLY FLOW METER READINGS TO CALCULATE CHILLED WATER SYSTEM

ENERGY USAGE. DDC SYSTEM SHALL CALCULATE AND RECORD PEAK LOADS ON DAILY,

WEEKLY AND MONTHLY INTERVALS, AND SHALL CALCULATE TOTAL ENERGY USAGE FOR THE

PAST HOUR, DAY, MONTH, AND YEAR. PROVIDE INFORMATION ON AN ENERGY DASHBOARD ON

THE GUI.
