TO A MINIMUM
THERMOSTATIC SETBACK CONTROLS THAT
ARE CONTROLLED BY EITHER AN AUTOMATIC
TIME CLOCK OR PROGRAMMABLE CONTROL
SYSTEM
SETBACK CONTROLS CAPABLE TO SET BACK
OR TEMPORARILY OPERATE THE SYSTEM TO
MAINTAIN ZONE TEMPERATURES DOWN TO
55°F OR UP TO 85°F
PROGRAMMABLE CONTROLS SHALL BE
CAPABLE OF STARTING AND STOPPING THE
SYSTEM FOR SEVEN DIFFERENT DAILY
SCHEDULES PER WEEK AND RETAIN
PROGRAMMING AND TIME SETTING DURING A
LOSS OF POWER FOR 10 HOURS

PRIOR TO SCHEDULED OCCUPANCY.
FAN COIL UNITS; ASSOCIATED HUMIDIFIERS:
VENTILATION:
WHEN THE KITCHEN RANGE HOOD EXHAUST FAN
IS OPERATING, THE NORMALLY CLOSED O.S.A.
DAMPER ON THE FAN COIL UNIT SHALL OPEN TO
PROVIDE O.S.A.; THE R.A. DAMPER SHALL CLOSE
TO MINIMUM POSITION, AND THE FAN SHALL
ACTIVATE. A DUCT MOUNTED THERMOSTAT
SHALL MODULATE THE HEATING COIL CONTROL
VALVE TO MAINTAIN A SUPPLY AIR
TEMPERATURE BETWEEN 60°F AND 80°F (ADJ.) TO
SATISFY THE PRIMARY SPACE TEMERATURE

HEATING WATER CONTROL VALVE AND CLOSE
OUTSIDE AIR DAMPER UPON DETECTION OF A
FREEZING CONDITION. FREEZESTAT SHALL BE
AUTOMATIC RESETTING TYPE.
SPACE HEATING:
UPON A CALL FOR HEAT FROM THE SPACE
TEMPERATURE SENSOR, THE NORMALLY CLOSED
O.S.A. DAMPER SHALL REMAIN CLOSED (IF
APPLICABLE), THE NORMALLY OPEN R.A. DAMPER
SHALL REMAIN OPEN (IF APPLICABLE), A
NORMALLY CLOSED CONTROL VALVE ON THE
HEATING WATER COIL SUPPLY SHALL OPEN AND
FAN COIL UNIT FAN SHALL ACTIVATE TO MAINTAIN
SPACE TEMPERATURE SETPOINT IN THE SPACE.
THE CONTROL VALVE SHALL BE CLOSED, AND
FAN COIL UNIT FAN SHALL BE OFF WHEN A CALL
FOR HEATING IS NO LONGER PRESENT.
SPACE COOLING:
UPON A CALL FOR COOLING FROM THE SPACE
TEMPERATURE SENSOR, THE NORMALLY CLOSED
O.S.A. DAMPER SHALL REMAIN CLOSED (IF
APPLICABLE), THE NORMALLY OPEN R.A. DAMPER
SHALL REMAIN OPEN IF APPLICABLE), A
NORMALLY CLOSED CONTROL VALVE ON THE
CHILLED WATER COIL SUPPLY SHALL OPEN, AND
FAN COIL UNIT FAN SHALL ACTIVATE TO MAINTAIN
SPACE TEMPERATURE SETPOINT IN THE SPACE.
THE CONTROL VALVE SHALL BE CLOSED, AND
FAN COIL UNIT FAN SHALL BE OFF WHEN A CALL

HUMIDIFICATION:
UPON A CALL FOR HUMIDIFICATION FROM THE
SPACE HUMIDITY SENSOR, THE FAN COIL UNIT
FAN SHALL ACTIVATE AT HEAT/LOW SPEED AND
THE UNIT SHALL OPERATE IN EITHER HEATING
OR COOLING MODE AS INDICATED ABOVE. THE
HUMIDIFIER SHALL BE ACTIVATED TO MAINTAIN
SPACE HUMIDITY OF 20%RH (ADJ. TO 30% MAX). IF
A CALL FOR HUMIDITY IS PRESENT WITH NO CALL
FOR HEAT OR COOLING, THE FAN COIL UNIT FAN
SHALL BE ACTIVATED TO CIRCULATE AIR AND
THE HUMIDIFIER SHALL OPERATE TO MAINTAIN
SPACE HUMIDITY OF 20%RH (ADJ.). PROVIDE
