SEQUENCE OF OPERATION FOR VARIABLE AIR VOLUME
AIR HANDLING UNIT AHU-1 WITH MINIMUM OUTSIDE AIR
1. GENERAL
1.1 UNIT IS NORMALLY STARTED AND STOPPED REMOTELY AT THE ECC. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO" POSITION. "HAND" AND "OFF" POSITIONS SHALL BE USED ONLY FOR MAINTENANCE. WHEN THE UNIT IS "OFF" D-1, D-2 & D-3 SHALL BE FULLY CLOSED. WHEN THE UNIT IS "ON" D-1, D-2 & D-3 SHALL BE FULLY OPEN.

5. FREEZE PROTECTION
5.1
SUPPLY AIR TEMPERATURE, SENSED BY TT-1, SHALL BE MAINTAINED AT SETPOINT VIA DIGITAL CONTROL PANEL
BY MODULATING V-1 OR V-2 IN SEQUENCE.
THE SUPPLY AIR FLOW SHALL BE CONTROLLED BY THE DIGITAL CONTROL PANEL MODULATING THE SUPPLY FANS SPEED IN UNISON TO MAINTAIN 1.5" OF DUCT STATIC PRESSURE (FIELD ADJUSTABLE), SENSED BY SPS-1.
THE DIGITAL CONTROL PANEL, USING TOTAL SUPPLY AIR AND RELIEF AIR FLOW SIGNALS, SHALL RESET THE RELIEF AIR FAN'S CONTROLLER IN UNISON TO MAINTAIN A CONSTANT AIR FLOW DIFFERENCE BETWEEN THE
SUPPLY AIR AND THE RELIEF AIR FLOWS EQUAL TO MINIMUM OUTSIDE AIR AND RELIEF AIR.
USING HIGH PRESSURE SENSOR SPS-2 LOCATED AT THE SUPPLY FAN DISCHARGE, SHALL PREVENT THE SUPPLY FAN FROM DEVELOPING OVER 3" OF STATIC PRESSURE (FIELD ADJUSTABLE). IF STATIC PRESSURE AT SPS-2 DOES EXCEED 3" THE SUPPLY AIR FAN SHALL STOP. SPS-2 SHALL BE HARDWIRED TO THE SUPPLY FAN CONTROLLER AND UNIT SHALL BE SHUTDOWN IN HAND,AUTO OR BYPASS MODE. SPS-2 WILL REQUIRE MANUAL
RESET AT THE DEVICE.
IF THE PREHEAT AIR TEMPERATURE AS SENSED BY TT-3 FALLS BELOW 45°F [7°C], AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND ECC. IF THIS TEMPERATURE FALLS BELOW 40°F [4.4°C], AS SENSED BY THE TSL THE SUPPLY AND RELIEF FANS SHALL SHUT DOWN AND A CRITICAL ALARM SHALL INDICATE AT THE DIGITAL CONTROL PANEL AND ECC. TSL SHALL BE HARDWIRED TO THE SUPPLY FAN CONTROLLER AND UNIT SHALL BE SHUTDOWN IN HAND,AUTO OR BYPASS MODE. TSL WILL REQUIRE MANUAL RESET AT THE DEVICE.
WHEN THE DIGITAL CONTROL PANEL IS NOT CALLING FOR HUMIDITY, SENSED BY RELIEF AIR HUMIDITY H-1, 2-WAY "ON-OFF" CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE DIGITAL CONTROL PANEL IS CALLING
FOR HUMIDITY, V-3 SHALL REMAIN OPEN.
RELIEF AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT OF 35% RH (ADJ) VIA DIGITAL CONTROL PANEL BY MODULATING CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP SHALL OVERRIDE THIS CONTROL TO MAINTAIN HUMIDITY OF 80% AS SENSED BY H-2. DCP SHALL CLOSE VALVE V-3 WHENEVER THE SUPPLY FAN IS OFF. VALVE V-4 SHALL BE INTERLOCKED WITH A TEMPERATURE SWITCH TO KEEP THE
HUMIDIFIER OFF UNTIL CONDENSATE TEMPERATURE APPROACHES STEAM TEMPERATURE.

RELATIVE HUMIDITY AS MEASURED BY HUMIDISTATS LOCATED IN THE SIX CLEAN ROOMS AND HD STORAGE SHALL MODULATE THE CONTROL VALVE THROUGH THE BMS IN ORDER TO MAINTAIN THE
SPACE RELATIVE HUMIDITY SO IT DOES NOT FALL BELOW 30% RH. ON A CALL FOR
HUMIDIFICATION, HUMIDIFIER VALVE V-1 SHALL MODULATE TO MAINTAIN THE AIR HUMIDITY SET POINT TO 30% (ADJUSTABLE). THE HIGH LIMIT HUMIDITY SENSOR, LOCATED IN THE SUPPLY AIR DUCT 10 FEET AWAY FROM THE HUMIDIFIER SHALL DISABLE THE HUMIDIFIER AND GIVE AN ALARM SIGNAL TO THE ECC, IF THE SUPPLY AIR HUMIDITY EXCEEDS 90% RH (ADJUSTABLE). THE AIRFLOW
SWITCH SHALL PROVE AIRFLOW BEFORE HUMIDITY CONTROLS ARE ACTIVATED.
