SEQUENCE OF OPERATION

BUILDING AUTOMATION SYSTEM INTERFACE:

THE BUILDING AUTOMATION SYSTEM (BAS) SHALL SEND THE DDC CONTROLLER

OCCUPIED, UNOCCUPIED, OPTIMUM START, NIGHT HEAT/COOL, AND TIMED

OVERRIDE COMMANDS. THE BAS SHALL ALSO SEND SPACE TEMPERATURE

SETPOINT TO THE CONTROLLER. IF COMMUNICATION IS LOST WITH THE BAS, THE

CONTROLLER SHALL OPERATE IN THE OCCUPIED COOLING MODE USING ITS

DEFAULT SPACE TEMPERATURE SETPOINT.

SUPPLY FAN:

THE SUPPLY FAN SHALL BE OFF IN UNOCCUPIED MODE. WHEN THE CONTROLLER IS

IN THE OCCUPIED MODE, THE SUPPLY FAN SHALL BE ENABLED. IF THE SUPPLY FAN

FAILS TO PROVE STATUS FOR 30 SECONDS (ADJ), THE FAN SHALL BE COMMANDED

OFF, THE OUTDOOR AIR DAMPER SHALL BE CLOSED, COOLING/HEATING SHALL BE

DISABLED, AND AN ALARM SHALL BE SENT TO THE BAS. A MANUAL RESET SHALL BE

REQUIRED TO RESTART THE FAN.

HEATING/COOLING MODE:

WHEN THE SPACE TEMPERATURE RISES ONE DEGREE (ADJ) ABOVE THE OCCUPIED

COOLING SETPOINT, THE MODE SHALL TRANSITION TO COOLING. WHEN THE SPACE

TEMPERATURE FALLS ONE DEGREE (ADJ) BELOW THE OCCUPIED HEATING

SETPOINT, THE MODE SHALL TRANSITION TO HEATING. WHEN THE SPACE

TEMPERATURE IS BETWEEN ONE DEGREE (ADJ) ABOVE THE OCCUPIED COOLING

SETPOINT AND ONE DEGREE (ADJ) BELOW THE OCCUPIED HEATING SETPOINT, THE

MODE SHALL REMAIN IN ITS LAST STATE. IF THE SPACE TEMPERATURE INPUT FAILS,

THE MODE SHALL REMAIN IN ITS LAST STATE AND AN ALARM SHALL BE SENT TO

THE BAS. IF THE LOCAL (AND COMMUNICATED) SETPOINTS(S) FAIL, THE

CONTROLLER WILL USE ITS DEFAULT SETPOINTS AND AN ALARM SHALL BE SENT TO

THE BAS.

OCCUPIED MODE:

DURING OCCUPIED MODE, THE OUTDOOR AIR DAMPER SHALL BE OPEN AND THE SUPPLY

FAN SHALL OPERATE AND MODULATE ITS SPEED AS REQUIRED TO MEET THE SPACE

TEMPERATURE SETPOINT. ONCE THE SETPOINT HAS BEEN ACHIEVED, THE OUTDOOR AIR

DAMPER SHALL BE CLOSED AND THE SUPPLY FAN SHALL BE DISABLED.

COOLING MODE:

ON A RISE IN SPACE TEMPERATURE ABOVE THE SPACE COOLING SETPOINT S.P.

(ADJ) THE DDC CONTROLLER SHALL MODULATE THE CHILLED WATER VALVE TO

MAINTAIN DISCHARGE AIR TEMPERATURE SETPOINT, 55 DEGREES (ADJ). ON A

CONTINUED RISE IN SPACE TEMPERATURE ABOVE THE SPACE COOLING SETPOINT

(ADJ), ONCE THE CHILLED WATER VALVE IS FULLY OPEN, THE DDC CONTROLLER

SHALL SIGNAL THE SUPPLY FAN VFD TO MODULATE THE SUPPLY FAN SPEED UP TO

ITS MAXIMUM SETTING AS REQUIRED TO MAINTAIN THE SPACE TEMPERATURE

SETPOINT. ON A FALL IN SPACE TEMPERATURE, THE SUPPLY FAN SPEED SHALL BE

MODULATED BACK TO ITS MINIMUM SPEED SETTING. ON A CONTINUED FALL IN

SPACE TEMPERATURE BELOW THE SPACE TEMPERATURE SETPOINT, AND WHEN

THE SUPPLY FAN IS AT ITS MINIMUM SPEED, THE DISCHARGE TEMPERATURE

SETPOINT SHALL BE GRADUALLY RESET UP TO NEUTRAL SPACE TEMPERATURE, 75º

(ADJ).

HEATING MODE:

ON A FALL IN SPACE TEMPERATURE BELOW THE SPACE HEATING TEMPERATURE

SETPOINT (ADJ), THE DDC CONTROLLER SHALL MODULATE THE HOT WATER

RE-HEAT VALVE TO MAINTAIN DISCHARGE AIR TEMPERATURE TO THE SETPOINT OF

THE DDC CONTROLLER. ON A CONTINUED FALL IN SPACE TEMPERATURE BELOW

THE SPACE HEATING TEMPERATURE SETPOINT (ADJ), ONCE THE HOT WATER VALVE

IS FULLY OPEN, THE DDC CONTROLLER SHALL SIGNAL THE SUPPLY FAN VFD TO

MODULATE THE SUPPLY FAN SPEED UP TO ITS MAXIMUM SETTING AS REQUIRED TO

MAINTAIN THE SPACE SETPOINT. ON A RISE IN SPACE TEMPERATURE, THE SUPPLY

FAN SPEED SHALL BE MODULATED BACK TO ITS MINIMUM SPEED SETTING. ON A

CONTINUED RISE IN SPACE TEMPERATURE ABOVE THE SPACE HEATING SETPOINT,

AND WHEN THE SUPPLY FAN IS AT MINIMUM SPEED, THE DISCHARGE

TEMPERATURE SETPOINT SHALL BE GRADUALLY RESET UP TO NEUTRAL SPACE

TEMPERATURE, 75ºF (ADJ). THE DISCHARGE AIR SETPOINT SHALL BE INVERSELY

RESET FROM SPACE TEMPERATURE.

DEHUMIDIFICATION MODE:

ON A RISE IN SPACE RELATIVE HUMIDITY TO THE SETPOINT OF THE DDC

CONTROLLER, THE DDC CONTROLLER SHALL MODULATE THE CHILLED WATER

VALVE FULLY OPEN TO THE COIL. SHOULD THE DEHUMIDIFICATION PROCESS

CAUSE THE SPACE TO OVER COOL, THE DDC CONTROLLER SHALL MODULATE THE

REHEAT VALVE OPEN TO MAINTAIN THE SPACE HEATING TEMPERATURE SETPOINT.

MORNING WARM-UP:

DURING OPTIMAL START, IF THE SPACE TEMPERATURE IS 1.5°F (ADJ) OR MORE

BELOW THE OCCUPIED HEATING SETPOINT, THE MORNING WARM-UP SEQUENCE

SHALL BE ACTIVATED. THE SUPPLY FAN SHALL START, THE HOT WATER VALVE

SHALL MODULATE OPEN, AND THE OUTDOOR AIR DAMPER SHALL REMAIN CLOSED.

MORNING WARM-UP MODE SHALL TERMINATE WHEN THE SPACE TEMPERATURE

REACHES THE OCCUPIED HEATING SETPOINT OR THE OCCUPIED TIME PERIOD HAS

STARTED.

MORNING COOL-DOWN:

DURING OPTIMAL START, IF THE SPACE TEMPERATURE IS 1.5°F (ADJ) OR MORE

ABOVE THE OCCUPIED COOLING SETPOINT, THE MORNING COOL-DOWN SEQUENCE

SHALL BE ACTIVATED. THE SUPPLY FAN SHALL START, THE CHILLED WATER VALVE

SHALL MODULATE OPEN, AND THE OUTDOOR AIR DAMPER SHALL REMAIN CLOSED.

MORNING COOL-DOWN MODE SHALL TERMINATE WHEN THE SPACE TEMPERATURE

REACHES THE OCCUPIED COOLING SETPOINT OR THE OCCUPIED TIME PERIOD HAS

STARTED.

FREEZE PROTECTION:

IF HOT WATER COIL DISCHARGE AIR TEMPERATURE FALLS BELOW 40°F DURING

HEATING MODE, THE FREEZESTAT SHALL CLOSE THE OUTSIDE AIR DAMPER,

DE-ENERGIZE THE AHU SUPPLY FAN AND FULLY OPEN THE HOT WATER AND

CHILLED WATER VALVES TO COIL.

UNOCCUPIED MODE:

DURING UNOCCUPIED MODE THE DDC CONTROLLER SHALL CYCLE THE UNIT TO

MAINTAIN A REDUCED HEATING SETPOINT, 55ºF (ADJ), AND A RAISED COOLING AND

RELATIVE HUMIDITY SETPOINT, 85ºF/60% RH (ADJ), WHILE MAINTAINTING THE

OUTDOOR AIR DAMPER FULLY CLOSED.

SAFETY CONTROL:

SMOKE DETECTOR SHALL BE PROVIDED BY FIRE ALARM CONTRACTOR. THROUGH

DDC CONTROL IT SHALL DE-ENERGIZE THE ASSOCIATED AHU, SIGNAL FIRE ALARM

PANEL AND CLOSE THE OUTSIDE AIR DAMPER UPON THE DETECTION OF THE

PRODUCTS OF COMBUSTION.

ALARMS:

ALARM IF LEAVING AIR TEMPERATURE EXCEEDS 60°F IN COOLING MODE OR DROPS

BELOW 50°F IN HEATING MODE. ALARM IF AHU SUPPLY FAN FAILS TO START OR

FAILS DURING OPERATION. ALARM IF UNIT DISCHARGE STATIC PRESSURE EXCEEDS

5" W.G. ALARM IF CONDENSATE REACHES HIGH LEVEL. ALARM UPON SMOKE

DETECTOR ACTIVATION.

DEMAND CONTROL VENTILATION:

IF ANY SPACE CARBON DIOXIDE LEVEL FALLS BELOW SETPOINT (1,000 PPM, ADJ.),

THE OUTSIDE AIRFLOW RATE SHALL BE AT THE MINIMUM SCHEDULED VALUE AS

INDICATED IN THE EQUIPMENT SCHEDULE. AS LEVEL INCREASES ABOVE SETPOINT,

THE OUTSIDE AIR DAMPER SHALL PROPORTIONALLY MODULATE OPEN TO

GENERATE THE SCHEDULED MAX OUTSIDE AIRFLOW RATE OVER A 1 HOUR (ADJ.)

TIME PERIOD UNTIL THE LEVEL FALLS BELOW THE SETPOINT, AFTER WHICH THE

DAMPER POSITION SHALL RETURN TO MINIMUM.
