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", D-1 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:

2.1 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

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

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

THE OUTSIDE AIR TEMPERATURE FALLS TO 78 F AND REMAINS THERE FOR

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

ALARM WHEN THE DIFFERENTIAL PRESSURE SWITCH REACHES ITS SETPOINT

INDICATING THAT THE FILTER IS DIRTY AND SHOULD BE CHANGED.

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

ALARM SIGNAL SHALL BE INDICATED AT THE DCP AND ECC. IF 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

SHALL CLOSE. EXHAUST FANS SERVING THE SAME SPACE AS THE SUPPLY

7. ENERGY RECOVERY COIL FROST PROTECTION

TO DROP 1 F BELOW SETPOINT FOR 5 MINUTES, THE DCP SHALL OPEN

�RISES 1 F ABOVE SET POINT FOR 5 MINUTES AND THE FACE AND 5.1 IF THE AIR TEMPERATURE, AS SENSED BY T-1, FALLS BELOW 45 F, AN

TEMPERATURE FALLS BELOW 40 F, AS SENSED BY FREEZESTAT T-3, THE

STEAM CONTROL VALVE,

TWO-WAY,

OPEN/CLOSE

ENERGIZED BY THE DCP. THE DCP SHALL MONITOR THE UNIT DISCHARGE

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