FAN COIL

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 80°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.

SUPPLY FAN:

THE SUPPLY FAN SHALL RUN ANYTIME THE UNIT IS COMMANDED TO RUN, UNLESS SHUTDOWN ON SAFETIES. TO PREVENT SHORT CYCLING, THE SUPPLY FAN SHALL HAVE A USER DEFINABLE (ADJ.)

MINIMUM RUNTIME.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• SUPPLY FAN FAILURE: COMMANDED ON, BUT THE STATUS IS OFF.

• SUPPLY FAN IN HAND: COMMANDED OFF, BUT THE STATUS IS ON.

• SUPPLY FAN RUNTIME EXCEEDED: STATUS RUNTIME EXCEEDS A USER DEFINABLE LIMIT (ADJ.).

COOLING COIL VALVE:

THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND MODULATE THE COOLING COIL VALVE

TO MAINTAIN ITS COOLING SETPOINT.

THE COOLING SHALL BE ENABLED WHENEVER:

• THE ZONE TEMPERATURE IS ABOVE COOLING SETPOINT.

• AND THE SUPPLY FAN STATUS IS ON.

• AND THE HEATING IS NOT ACTIVE.

HEATING COIL VALVE:

THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND MODULATE THE HEATING COIL VALVE

TO MAINTAIN ITS HEATING SETPOINT.

THE HEATING SHALL BE ENABLED WHENEVER:

• THE ZONE TEMPERATURE IS BELOW HEATING SETPOINT.

• AND THE SUPPLY FAN STATUS IS ON.

• AND THE COOLING IS NOT ACTIVE.

DEHUMIDIFICATION:

THE CONTROLLER SHALL MEASURE THE ZONE HUMIDITY AND OVERRIDE THE COOLING SEQUENCE TO

MAINTAIN RETURN AIR HUMIDITY AT OR BELOW 60% RH (ADJ.).

DURING DEHUMIDIFICATION, THE HEATING SHALL MODULATE TO MAINTAIN A SETPOINT 1°F (ADJ.) LESS

THAN THE ZONE COOLING SETPOINT.

DEHUMIDIFICATION SHALL BE ENABLED WHENEVER:

• THE SUPPLY FAN STATUS IS ON.

• AND ZONE TEMPERATURE IS GREATER THAN THE COOLING SETPOINT.

FINAL FILTER HOURS:

THE CONTROLLER SHALL MONITOR THE FAN RUNTIME.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• FINAL FILTER CHANGE REQUIRED: FINAL FILTER HAS BEEN IN USE FOR MORE THAN

2200 HRS (ADJ.).

ZONE HUMIDITY:

THE CONTROLLER SHALL MONITOR THE ZONE HUMIDITY AND USE AS REQUIRED FOR HUMIDITY

CONTROL.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

• HIGH ZONE HUMIDITY: IF THE ZONE HUMIDITY IS GREATER THAN 70% (ADJ.).

• LOW ZONE HUMIDITY: IF THE ZONE HUMIDITY IS LESS THAN 35% (ADJ.).

ELECTRIC METER:

THE CONTROLLER SHALL MONITOR THE ELECTRIC METER FOR ELECTRIC CONSUMPTION ON A CONTINUAL BASIS.

THESE VALUES SHALL BE MADE AVAILABLE TO THE SYSTEM AT ALL TIMES.

ALARM SHALL BE GENERATED AS FOLLOWS:

• METER FAILURE: SENSOR READING INDICATES A LOSS OF PULSE OUTPUT FROM THE ELECTRIC METER.

PEAK DEMAND HISTORY:

THE CONTROLLER SHALL MONITOR AND RECORD THE PEAK (HIGH AND LOW) DEMAND READINGS FROM THE ELECTRIC METER. PEAK READINGS SHALL BE RECORDED ON A DAILY, MONTH-TO-DATE, AND YEAR-TO-DATE BASIS.

USAGE HISTORY:

THE CONTROLLER SHALL MONITOR AND RECORD ELECTRIC METER READINGS SO AS TO PROVIDE A POWER CONSUMPTION HISTORY. USAGE READINGS SHALL BE RECORDED ON A DAILY, MONTH-TO-DATE, AND YEAR-TO-DATE

BASIS.

DEMAND LEVELS:

THE CONTROLLER SHALL SET THE SYSTEM DEMAND LEVEL (ADJ.) BASED ON THE CURRENT POWER CONSUMPTION READINGS FROM THE ELECTRIC METER. THERE SHALL BE SIX DAILY TIME PERIODS IN WHICH THE DEMAND SHALL BE ADJUSTED ON THREE LEVELS. THESE DEMAND LEVELS SHALL BE AVAILABLE FOR FACILITY EQUIPMENT TO UTILIZE

FOR DEMAND LIMITING.

• DEMAND LEVEL 1: POWER CONSUMPTION HAS EXCEEDED THE FIRST DEMAND LEVEL THRESHOLD (ADJ.).

• DEMAND LEVEL 2: POWER CONSUMPTION HAS EXCEEDED THE SECOND DEMAND LEVEL THRESHOLD (ADJ.).

• DEMAND LEVEL 3: POWER CONSUMPTION HAS EXCEEDED THE THIRD DEMAND LEVEL THRESHOLD (ADJ.).
