SEQUENCE OF OPERATION

1. GENERAL

1.1 UNIT IS NORMALLY STARTED AND STOPPED BY THE DCP OR

REMOTELY AT THE ECC. H-O-A SWITCH SHALL BE KEPT IN THE "AUTO"

POSITION. "HAND" AND "OFF" SHALL BE USED ONLY FOR MAINTENANCE.

WHEN THE UNIT IS "OFF", 31-CD1, 31CD-2 AND SD-1 SHALL BE FULLY

CLOSED. WHEN THE UNIT IS "ON", D1 AND SD-1 SHALL BE FULLY OPEN.

SMOKE DAMPER END SWITCH (ZS) AND OUTSIDE AIR DAMPER END

SWITCH (ZS) SHALL PREVENT FAN OPERATION UNTIL BOTH DAMPERS

REACH THEIR FULL OPEN POSITION. D-2 SHALL MODULATE IN

ACCORDANCE WITH THE FOLLOWING SEQUENCE:

2. TEMPERATURE CONTROL (31-P-5H)

2.1 THE SUPPLY AIR TEMPERATURE SENSED BY T-1 SHALL BE

MAINTAINED AT SETPOINT BY THE DCP MODULATING/CONTROLLING

THE ENERGY RECOVERY SYSTEM, THE PRE-HEAT COIL VALVE AND THE

FACE AND BY-PASS DAMPERS AND THE COOLING COIL VALVE AS

FOLLOWS:

DURING THE HEATING SEASON WHEN THE OUTSIDE AIR TEMPERATURE

�IS BELOW 50 F, THE HEAT RECOVERY SYSTEM PUMP 31-P-5H SHALL BE

ENERGIZED BY THE DCP. THE DCP SHALL MONITOR THE UNIT

DISCHARGE AIR TEMPERATURE (T-1). IF THE DISCHARGE AIR

�TEMPERATURE IS SENSED TO DROP 1 F BELOW SETPOINT FOR 5

MINUTES, THE DCP SHALL OPEN PRE-HEAT COIL VALVE V-2. THE DCP

SHALL THEN BEGIN MODULATING THE PRE-HEAT COIL FACE AND BY-

PASS DAMPERS TO MAINTAIN THE DISCHARGE AIR TEMPERATURE. IF

�THE DISCHARGE AIR TEMPERATURE RISES 1 F ABOVE SET POINT FOR

5 MINUTES AND THE FACE AND BY-PASS DAMPERS ARE IN FULL BY-

PASS, THE DCP SHALL CLOSE THE PRE-HEAT COIL VALVE V-2.

WHEN VALVE V-2 IS CLOSED AND THE DCP SENSES A DISCHARGE AIR

�TEMPERATURE 2 F ABOVE SETPOINT FOR 15 MINUTES, THE DCP SHALL

DE-ENERGIZE THE ENERGY RECOVERY SYSTEM CIRCULATING PUMP

31-P-5H AND ENERGIZE THE CHILLED WATER PUMP 31-P-1H (OR 31-P-2H

AS PROGRAMMED.) WITH THE CHILLED WATER PUMP ENERGIZED, THE

DCP SHALL MAINTAIN DISCHARGE AIR TEMPERATURE SETPOINT BY

MODULATING THE COOLING COIL VALVE V-1.

�WHEN THE OUTSIDE AIR TEMPERATURE IS SENSED TO BE 80 F, THE

DCP SHALL ENERGIZE THE ENERGY RECOVERY CIRCULATING PUMP

31-P-5H. THE PUMP SHALL REMAIN ENERGIZED AS LONG AS THE DCP

�SENSES THE OUTSIDE AIR TEMPERATURE TO BE 80 F OR ABOVE.

DISCHARGE AIR TEMPERATURE WILL CONTINUE TO BE MAINTAINED BY

MODULATION OF THE COOLING COIL VALVE V-1.

�WHEN THE OUTSIDE AIR TEMPERATURE FALLS TO 78 F AND REMAINS

THERE FOR 30 MINUTES, THE DCP SHALL DE-ENERGIZE THE

CIRCULATING PUMP 31-P-5H.

WHEN THE COOLING COIL VALVE V-1 IS CLOSED AND THE UNIT

�DISCHARGE AIR TEMPERATURE IS SENSED TO BE 1 F BELOW

SETPOINT FOR 5 MINUTES, THE DCP SHALL DE-ENERGIZE THE CHILLED

WATER PUMP AND ENERGIZE THE HEAT RECOVERY SYSTEM PUMP

(REGARDLESS OF OUTDOOR TEMPERATURE).

2. TEMPERATURE CONTROL (31-AH-2)

2.1 THE SUPPLY AIR TEMPERATURE, SENSED BY T-1, SHALL BE

MAINTAINED AT SETPOINT BY THE DCP MODULATING/CONTROLLING

THE PRE-HEAT COIL VALVE AND THE FACE AND BY-PASS DAMPERS

AND THE COOLING COIL VALVE AS FOLLOWS:

THE DCP SHALL MONITOR THE UNIT DISCHARGE AIR TEMPERATURE

(T- �1). IF THE DISCHARGE AIR TEMPERATURE IS SENSED TO DROP 1 F

BELOW SETPOINT FOR 5 MINUTES, THE DCP SHALL OPEN PRE-HEAT

COIL VALVE V-2. THE DCP SHALL THEN BEGIN MODULATING THE PRE-

HEAT COIL FACE AND BY-PASS DAMPERS TO MAINTAIN THE

DISCHARGE AIR TEMPERATURE. IF THE DISCHARGE AIR TEMPERATURE

�RISES 1 F ABOVE SET POINT FOR 5 MINUTES AND THE FACE AND BY-

PASS DAMPERS ARE IN FULL BY-PASS, THE DCP SHALL CLOSE THE

PRE-HEAT COIL VALVE V-2.

WHEN VALVE V-2 IS CLOSED AND THE DCP SENSES A DISCHARGE AIR

�TEMPERATURE 1 F ABOVE SETPOINT FOR 5 MINUTES, THE DCP SHALL

BEGIN MODULATING THE COOLING COIL VALVE V-1 TO MAINTAIN THE

UNIT DISCHARGE AIR TEMPERATURE. THE REVERSE SEQUENCE

OCCURS ON A FALL IN DISCHARGE AIR TEMPERATURE.

3. AIRFLOW MONITORING

3.1 THE DCP SHALL MONITOR THE UNIT PRE-FILTER/AFTER FILTER, AND

FINAL FILTER AND SHALL ALARM WHEN THE DIFFERENTIAL PRESSURE

SWITCH REACHES ITS SETPOINT INDICATING THAT THE FILTER IS DIRTY

4. HUMIDITY CONTROL

4.1 WHEN THE DCP IS NOT CALLING FOR HUMIDITY, SENSED BY H-1, "ON-

OFF" TWO-WAY CONTROL VALVE V-3 SHALL REMAIN CLOSED. WHEN THE

DCP IS CALLING FOR HUMIDITY, V-3 SHALL REMAIN OPEN AND V-1

(COOLING COIL CONTROL VALVE) SHALL REMAIN CLOSED.

4.2 THE SPACE HUMIDITY, SENSED BY H-1, SHALL BE MAINTAINED AT

SETPOINT BY THE DCP MODULATING HUMIDITY CONTROL VALVE V-4 TO

MAINTAIN THE DESIRED RELATIVE 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. VALVE V-4 SHALL ALSO BE INTERLOCKED WITH THE

SUPPLY FAN MOTOR STARTER SO THAT, WHEN THE FAN IS OFF, THE

CONTROL SIGNAL TO THE VALVE WILL BLEED TO ATMOSPHERE THROUGH

A SOLENOID VALVE ALLOWING VALVE V-4 TO GO FULLY CLOSED.

5. FREEZE PROTECTION

5.1 IF THE AIR TEMPERATURE, AS SENSED BY T- �3, FALLS BELOW 45 F, AN

ALARM SIGNAL SHALL BE INDICATED AT THE DCP AND ECC. 31-AHU-1

�ONLY: IF THIS TEMPERATURE FALLS BELOW 40 F, AS SENSED BY

FREEZESTAT T-4, THE UNIT SUPPLY FAN SHALL SHUT DOWN (THROUGH A

HARDWIRED INTERLOCK BETWEEN THE FREEZESTAT CONTROL RELAY

AND FAN MOTOR STARTER) AND A CRITICAL ALARM SHALL BE INDICATED

AT THE DCP AND ECC.

6. AUTOMATIC SHUTDOWN/RESTART

6.1 WHEN SMOKE IS DETECTED BY DUCT SMOKE DETECTOR F SD, THE

SUPPLY FAN SHALL SHUT "OFF" (THROUGH A HARDWIRED INTERLOCK

BETWEEN THE SMOKE DETECTOR AND FAN MOTOR STARTER) AND AN

ALARM SIGNAL SHALL BE TRANSMITTED TO THE ECC AND TO THE FIRE

ALARM SYSTEM. THE OUTSIDE AIR DAMPER AND SMOKE DAMPER IN THE

SUPPLY DUCT SHALL CLOSE. EXHAUST FANS SERVING THE SAME SPACE

AS THE SUPPLY FAN SHALL CONTINUE TO RUN. SUPPLY FAN SHALL

RESTART AND SMOKE DAMPER AND OUTSIDE AIR DAMPER SHALL OPEN

WHEN FIRE ALARM CIRCUIT IS MANUALLY RESET.

7. ENERGY RECOVERY COIL FROST PROTECTION

7.1 THE PNEUMATICALLY CONTROLLED, 3-WAY MIXING VALVE V-5 SHALL

BE MODULATED BY THE DCP, MIXING SUPPLY AND RETURN GLYCOL TO

�MAINTAIN A MINIMUM OF 35 F GLYCOL TEMPERATURE TO ENERGY

RECOVERY COILS 31-ERC-1 AND 31-ERC-2 AS SENSED BY THE DCP

THROUGH TEMPERATURE SENSOR T-5.

8 UV-C LIGHT OPERATION

8.1 PROVIDE THE FOLLOWING SAFETY FUNCTIONS. ALL SAFETIES SHALL

BE OPERATIONAL REGARDLESS OF FAN MODE (HAND, OFF, AUTO, OR
