EXISTING TIME CLOCK. EXISTING TIME CLOCK STARTS THE CHW PUMP

AND ALL AIR HANDLING UNITS IN THE THEATER BUILDING.

2. NEW CHW PUMP CAN BE STARTED MANUALLY VIA AN EXISTING H-O-A

SWITCH LOCATED IN THE PROJECTION ROOM AT THE THEATER BLDG.

3. EXISTING CHILLER CONTROL REMAINS UNCHANGED:

A. THE EXISTING CHILLER STARTS AFTER A TIME DELAY AND UPON

VERIFICATION OF CHW FLOW.

B. THE CHILLER CAN BE MANUALLY STARTED VIA AN EXISTING

INDIVIDUAL H-O-A SWITCH LOCATED IN THE PROJECTION ROOM AT

THE THEATER BLDG.

5. EXISTING CONTROLS FOR AIR HANDLING UNITS REMAIN UNCHANGED:

A. EXISTING AIR HANDLING UNITS CAN BE MANUALLY STARTED VIA
