SEQUENCE OF OPERATION - ENERGY RECOVERY VENTILATOR

EQUIPMENT

THE AIRSIDE SYSTEMS, AS IT APPLIES TO THE BUILDING AUTOMATION SYSTEM

(BAS), CONSISTS OF THE FOLLOWING EQUIPMENT:

ENERGY RECOVERY VENTILATOR, ERV-1

RUN CONDITIONS

THE UNIT SHALL RUN BASED UPON A BAS OPERATOR ADJUSTABLE SCHEDULE

(EQUIPMENT SCHEDULE TO BE COORDINATED WITH OWNER DURING THE INITIAL

SETUP OF CONTROLS). THE OUTSIDE AIR FAN AND EXHAUST AIR FAN DURING

OCCUPIED MODE, THE UNIT SHALL RUN WHEN THE RESPECTIVE DEDICATED

OUTDOOR AIR SYSTEM (DOAS) RUNS, UNLESS SHUTDOWN ON SAFETIES. THE

UNIT SHALL SHUT DOWN WHEN THE INTERLOCKED DOAS UNIT IS SHUT DOWN.

THE ERV SHALL BE INTERLOCKED AS FOLLOWS:

ERV-1: INTERLOCKED DOAS-1

OUTSIDE AND EXHAUST AIR FANS

THE OUTSIDE AIR AND EXHAUST AIR FANS SHALL RUN ANYTIME THE UNIT IS

COMMANDED TO RUN UNLESS SHUTDOWN ON SAFETIES. THE FANS SHALL RUN

AT CONSTANT SPEED.

OUTSIDE AIR AND EXHAUST AIR DAMPERS

THE OUTSIDE AIR AND EXHAUST AIR DAMPERS SHALL OPEN ANYTIME THE UNIT

RUNS AND SHALL CLOSE ANYTIME THE UNIT STOPS. THE FANS SHALL START

ONLY AFTER THE DAMPER STATUS HAS PROVEN EACH DAMPER IS OPEN.

FILTER DIFFERENTIAL PRESSURE MONITOR

A DIFFERENTIAL PRESSURE SWITCH SHALL MONITOR THE DIFFERENTIAL

PRESSURE ACROSS THE OUTSIDE AIR AND EXHAUST AIR FILTERS.

ALARMS AND SHUTDOWNS

HVAC EMERGENCY SHUTDOWN: THE UNIT SHALL SHUT DOWN BASED ON A
