Control Notes

1. THE CHILLED WATER CONTROL VALVE SHALL MODULATE TO MAINTAIN 55°F LEAVING AIR TEMPERATURE. IF THE OUTSIDE AIR TEMPERATURE

DROPS BELOW 55°F THE VALVE SHALL CLOSE OFF TO ALLOW THE PRE-HEAT COIL TO MAINTAIN 60°F LEAVING AIR TEMPERATURE.

2. IF THE FREEZE STAT SENSES TEMPERATURE BELOW 40°F LEAVING AIR TEMPERATURE IT SHALL SHUT OFF THE SUPPLY AIR FAN AND THE GENERAL

EXHAUST FAN. UP ONE MANUAL RESET THE SYSTEM SHALL GO BACK TO NORMAL OPERATION.

3. THE ZONE RE-HEAT COILS SHALL BE CONTROLLED BY AN SENSOR IN THE HOOD LABORATORIES. THE THERMOSTAT SHALL MAINTAIN 72°F ROOM

AIR TEMPERATURE BY MODULATING THE RE-HEAT STEAM CONTROL VALVE.

4. THE VAV DIFFUSERS ARE SELF CONTAINED. THEY SHALL BE SET AT 72°F FOR THE OFFICE AREAS. THIS TEMPERATURE MAY BE RESET AT THE

OCCUPANTS REQUEST FOR HIS NOMINAL TEMPERATURE SETTING.

5. THE AHU SHALL BE FURNISHED WITH AN LEAVING SMOKE DETECTOR. THE SMOKE DETECTOR SENSING SMOKE IN THE LEAVING SUPPLY AIR DUCT SHALL SHUT THE FAN DOWN. THE EXHAUST SHALL BE KEPT IN OPERATION FOR SMOKE REMOVAL.
