EXHAUST FAN CONTROL

WHEN THE SPACE OCCUPANCY STATUS IS OCCUPIED, THE EXHAUST AIR AND INTAKE

AIR DAMPER SHALL BE COMMANDED OPEN. WHEN THE EXHAUST AIR AND INTAKE AIR

DAMPERS ARE PROVEN OPEN, THE EXHAUST FAN SHALL BE ENABLED AND

COMMANDED TO RUN.

WHEN THE SPACE OCCUPANCY STATUS IS UN-OCCUPIED, THE EXHAUST FAN SHALL

BE DISABLED AND COMMANDED TO STOP. WHEN THE EXHAUST FAN STATUS IS

PROVEN OFF, THE EXHAUST AIR AND INTAKE AIR DAMPERS SHALL BE COMMANDED

CLOSE.

PROVIDE POSITIVE EXHAUST FAN STATUS VIA CURRENT SENSING RELAY AT FAN

MOTOR STARTER.

EXHAUST FAN H-O-A SWITCHES

HAND: WITH THE H-O-A SWITCH IN THE HAND POSITION, THE EXHAUST FAN SHALL

START AND RUN CONTINUOUSLY, SUBJECT TO SAFETIES AND DAMPER PROOFS. FAN

SHALL BE UNDER MANUAL OPERATOR CONTROL.

OFF: WITH THE H-O-A SWITCH IN THE OFF POSITION, THE EXHAUST FAN SHALL STOP.

AUTO: WITH THE H-O-A SWITCH IN THE AUTO POSITION, THE EXHAUST FAN SHALL

START AND RUN SUBJECT TO THE SUPPLY FAN RUNNING AND SAFETIES AND

DAMPER PROOFS. FAN SHALL BE UNDER CONTROL OF THE DDC HARDWARE.

PROOFS AND SAFETIES

THE EXHAUST FAN AND ALL DDC HARDWARE CONTROL LOOPS SHALL BE SUBJECT

TO PROOFS AND SAFETIES. SAFETIES SHALL BE DIRECT-HARDWIRE INTERLOCKED

TO THE MOTOR STARTER. DDC HARDWARE SHALL MONITOR ALL PROOFS AND

SAFETIES AND FAILURE OF ANY PROOF OR ACTIVATION OF ANY SAFETY SHALL

RESULT IN ALL CONTROL LOOPS BEING DISABLED AND THE EF FAN BEING

COMMANDED OFF UNTIL RESET.

SYSTEM MONITORING AND ALARMS

IF ANY PIECE OF EQUIPMENT FAILS TO PROVE STATUS AFTER IT IS COMMANDED, WITH A 20

SECOND (ADJUSTABLE) TIME DELAY, AN ALARM SHALL BE SENT TO THE DDC. THIS

INCLUDES FANS AND DAMPERS.

1. DDC SHALL MONITOR AND DISPLAY :

A. EXHAUST FAN STATUS (ON/OFF’ EACH).

B. EF ELECTRICAL CURRENT (FLA; EACH).

C. H-O-A SWITCH POSITION

2. DDC SHALL ALARM THE FOLLOWING

A. EXHAUST FAN FAILURE (EACH).

B. H-O-A SWITCH NOT IS 'AUTO' POSITION (60 MINUTE DELAY)

TRENDS: PROVIDE TREND DATA IN GRAPHIC FORMAT IN FIVE (5) MINUTE INCREMENTS FOR

ALL CONTROL POINTS.

RADIANT GAS HEATER CONTROL

THE RADIANT GAS HEATER SHALL BE ENABLED AND COMMANDED TO RUN WHEN THE SPACE

TEMPERATURE FALLS BELOW SETPOINT, 55 DEGREE F (ADJ.). UPON A RISE IS SPACE TEMPERATURE

ABOVE SPACE TEMPERATURE SETPOINT, THE RADIANT GAS HEATER SHALL BE DISABLED AND

COMMANDED TO STOP.

RADIANT GAS HEATERS SHALL BE PROVIDED WITH AN INTEGRAL CONTROLLER. THE SIGNAL

PROVIDED FROM THE CONTROL SYSTEM SHALL ONLY ACTIVATE THE RADIANT GAS HEATER.

PROVIDE POSITIVE RADIANT GAS HEATER STATUS VIA CURRENT SENSING RELAY AT RADIANT GAS

HEATER CONNECTION..

SAFETIES

THE UNIT SHALL RUN SUBJECT TO THE UNIT MANUFACTURER'S SAFETIES BUILT IN TO THE INTEGRAL

CONTROLLER.

SYSTEM MONITORING AND ALARMS

IF ANY PIECE OF EQUIPMENT FAILS TO PROVE STATUS AFTER IT IS COMMANDED, WITH A 20 SECOND

(ADJUSTABLE) TIME DELAY, AN ALARM SHALL BE SENT TO THE DDC.

1. DDC SHALL MONITOR AND DISPLAY :

A. RADIANT GAS HEATER STATUS (ON/OFF EACH).

B. ZONE TEMPERATURE

2. DDC SHALL ALARM THE FOLLOWING

A. RADIANT GAS HEATER FAILURE (EACH).
