SEQUENCE OF OPERATIONS -

AHU FOR OR (MER 3117)

Project Title

SEQUENCE OF OPERATIONS - AHU FOR OR (MER 3117)

AHU FOR OF (MER #3117) SEQUENCE OF OPERATION

1. GENERAL

UNIT IS NORMALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO" POSITION. "HAND" AND

"OFF" POSITIONS SHALL BE USED FOR MAINTENANCE ONLY. WHEN THE UNIT IS "OFF" D-1 SHALL BE CLOSED. WHEN THE UNIT IS "ON" D-1 SHALL BE FULLY

OPENED.

2. TEMPERATURE CONTROL

SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATING V-1 AND V-2 IN SEQUENCE.

3. AIRFLOW CONTROL

THE SUPPLY AIRFLOW SHALL BE CONTROLLED BY DCP MODULATING THE SUPPLY FAN VARIABLE SPEED MOTOR CONTROLLER (VSMC) TO MAINTAIN 1.5"

OF DUCT STATIC PRESSURE (FIELD ADJUSTABLE) SENSED BY SPS-1.

THE DCP USING HIGH STATIC 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 EXCEEDS 3" THE SUPPLY FAN SHALL STOP.

4. HUMIDITY CONTROL

WHEN THE DCP IS NOT CALLING FOR HUMIDIFICATION SENSED BY ROOM HUMIDISTAT H-1, TWO-WAY "ON-OFF" CONTROL VALVE V-3 SHALL REMAIN

CLOSED. WHEN THE DCP IS CALLING FOR HUMIDIFICATION, V-3 SHALL REMAIN OPEN.

SPACE AIR HUMIDITY SHALL BE MAINTAINED AT SETPOINT VIA DCP BY MODULATION CONTROL VALVE V-4 TO MAINTAIN THE DESIRED HUMIDITY. THE DCP

SHALL OVERRIDE THE CONTROL TO MAINTAIN HUMIDITY IN SUPPLY DUCT BELOW 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. (FIELD VERIFY).

5. FREEZE PROTECTION

IF THE AIR TEMPERATURE SENSED BY T-2 FALLS BELOW 45F AN ALARM SIGNAL SHALL INDICATE AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS

BELOW 40F THE SUPPLY FAN SHALL SHUT DOWN, D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL INDICATE AT THE DCP AND BMS.

6. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY FAN SHALL SHUT OFF, DAMPE D-1 CLOSE AND AN ALARM SIGNAL

SHALL BE TRANSMITTED TO THE FIRE ALARM SYSTEM. SUPPLY FAN RESTARTS AND DAMPER D-1 OPENS WHEN THE FIRE ALARM CIRCUIT IS MANUALLY

RESET.

7. EMERGENCY CONSTANT SPEED OPERATION

UPON FAILURE OF VSMC THE SUPPLY AND EXHAUST FANS SHALL BE STARTED/STOPPED MANUALLY AT THE DCP OR THE BMS THROUGH THE BYPASS

STARTER. FANS SHALL THEN OPERATE AT CONSTANT SPEED.
