RUN CONDITIONS - SCHEDULED:

THE UNIT SHALL RUN ACCORDING TO A USER DEFINABLE TIME SCHEDULE IN THE FOLLOWING MODES:

· OCCUPIED MODE: THE UNIT SHALL MAINTAIN

· A 75°F (ADJ.) COOLING SETPOINT

· A 70°F (ADJ.) HEATING SETPOINT.

· UNOCCUPIED MODE (NIGHT SETBACK): THE UNIT SHALL MAINTAIN

· A 85°F (ADJ.) COOLING SETPOINT.

· A 60°F (ADJ.) HEATING SETPOINT.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· HIGH ZONE TEMP: IF THE ZONE TEMPERATURE IS GREATER THAN THE COOLING SETPOINT BY A USER

DEFINABLE AMOUNT (ADJ.).

· LOW ZONE TEMP: IF THE ZONE TEMPERATURE IS LESS THAN THE HEATING SETPOINT BY A USER DEFINABLE

AMOUNT (ADJ.).

ZONE SETPOINT ADJUST:

THE OCCUPANT SHALL BE ABLE TO ADJUST THE ZONE TEMPERATURE HEATING AND COOLING SETPOINTS AT THE

ZONE SENSOR.

ZONE OPTIMAL START:

THE UNIT SHALL USE AN OPTIMAL START ALGORITHM FOR MORNING START-UP. THIS ALGORITHM SHALL MINIMIZE THE UNOCCUPIED WARM-UP OR COOL-DOWN PERIOD WHILE STILL ACHIEVING COMFORT CONDITIONS BY THE

START OF SCHEDULED OCCUPIED PERIOD.

ZONE UNOCCUPIED OVERRIDE:

A TIMED LOCAL OVERRIDE CONTROL SHALL ALLOW AN OCCUPANT TO OVERRIDE THE SCHEDULE AND PLACE THE UNIT INTO AN OCCUPIED MODE FOR AN ADJUSTABLE PERIOD OF TIME. AT THE EXPIRATION OF THIS TIME, CONTROL OF THE UNIT SHALL AUTOMATICALLY RETURN TO THE SCHEDULE.

SPACE OCCUPIED MODE:

· SPACE THERMOSTAT SHALL MODULATE PRIMARY AIR DAMPER TO MAINTAIN SPACE TEMPERATURE.

· UPON CALL FOR HEAT, THE PRIMARY DAMPER SHALL CLOSE TO MINIMUM POSITION. UPON FURTHER CALL

FOR HEAT WITH PRIMARY AIR DAMPER IN MINIMUM POSITION, THE REHEAT CONTROL VALVE SHALL OPEN

AND MODULATE IN SEQUENCE TO MAINTAIN SPACE TEMPERATURE SET POINT.

· UPON CALL FOR COOLING, THE REHEAT VALVE SHALL MODULATE CLOSED. UPON A FURTHER CALL FOR COOLING, THE AIR DAMPER SHALL MODULATE OPEN AS REQUESTED TO PROVIDE COOLING AS SENSED BY

THE SPACE SENSOR.

HEATING WATER REHEATING:

THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND STAGE THE 3-WAY HEATING WATER VALVE TO

MAINTAIN THE HEATING AND COOLING MODE DISCHARGE AIR TEMPERATURES AS SCHEDULED.

THE REHEATING SHALL BE ENABLED WHENEVER:

· VAV BOX DAMPER IS IN THE OPEN POSITION AND IN THE HEATING MODE.

· VAV BOX DAMPER IS IN THE MINIMUM POSITION IN THE COOLING MODE.

IN THE OCCUPIED MODE WHEN SPACE TEMPERATURE CONDITIONS ARE MET AND THE VAV BOX DAMPER IS IN

THE MINIMUM

POSITION, THE CONTROLLER SHALL STAGE THE 3-WAY HEATING WATER VALVE TO MAINTAIN A DISCHARGE AIR

TEMPERATURE OF

75 °F IN THE COOLING MODE AND 70 °F IN THE HEATING MODE.

DISCHARGE AIR TEMPERATURE:

THE CONTROLLER SHALL MONITOR THE DISCHARGE AIR TEMPERATURE.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· HIGH DISCHARGE AIR TEMP: IF THE DISCHARGE AIR TEMPERATURE IS GREATER THAN 120°F (ADJ.).

· LOW DISCHARGE AIR TEMP: IF THE DISCHARGE AIR TEMPERATURE IS LESS THAN 40°F (ADJ.).
