SEQUENCE OF OPERATION

Exhaust Air Flow Control:

An air flow measuring station (Tek-Air) in the lab exhaust duct is used to control exhaust flow to exhaust CFM setpoint. A Pneumavalve through operator (VMA-EB-C and EP-1), will modulate to maintain the exhaust CFM setpoint. Upon the loss of the associated exhaust fan, the Pneumavalve will be overridden closed for a general exhaust and overridden open if serving a hood.

Supply Air Flow and Temperature Control:

A temperature sensor (TE-1) is located in the room. A dual duct mixing box supplies conditioned air to the room.

Air flow measuring stations are located on the mixing box to measure Cold deck and Total flow. The hot deck and cold deck dampers will modulate through operator (VMA-MB-C) and DPR-1, to maintain the total supply CFM setpoint. The sequence will on a fall in room temperature below setpoint, modulate open the hot deck damper from minimum CFM to maximum CFM to maintain room temperature setpoint. On a rise in space temperature above setpoint, the hot deck damper will close to minimum CFM and on a continued rise, open the cold deck damper from minimum CFM setpoint to maximum CFM setpoint to maintain room temperature setpoint. Upon the loss of the associated Supply fan, the mixing box will be overriden to a shutdown condition, which will close the Hot and Cold deck dampers.

The temperature sensor has an adjustable slide bar to offset the base setpoint +/- 2 degrees.
