DURING "OCCUPIED" MODE, THE CONTROL SYSTEM SHALLBE PLACED IN OPERATION, THE OUTSIDE AIR DAMPER SHALL OPEN AND THE SUPPLY FANSHALL RUN CONTINUOUSLY. THE CENTRAL CONTROL PANEL SHALL CONTROL, IN SEQUENCE,THE HEATING MODE AND COOLING MODE ACCORDING TO THE ZONE TEMPERATURE SENSORSSETPOINTS.

OCCUPIED OPERATION:

UNOCCUPIED OPERATION:THE CENTRAL CONTROL PANEL SHALL INDEX THE AHU FOR "UNOCCUPIED" PERIODSBASED ON USER DEFINED OCCUPANCY SCHEDULE. DURING "UNOCCUPIED" MODE THE UNITFAN, HEATING, AND COOLING SHALL CYCLE TO MAINTAIN THE HEATING AND COOLING SETPOINTS (64 F HEATING ADJ, 81 F COOLING ADJ) AND THE OUTSIDE AIR DAMPER SHALLREMAIN CLOSED.COOLING MODE:UPON A MAJORITY CALL FOR COOLING BY THE ZONE TEMPERATURE SENSORS, THECOMPRESSOR(S) SHALL BE ENERGIZED. WHEN ALL ZONE TEMPERATURE SENSORSHAVE BEEN SATISFIED, THE REVERSE SHALL OCCUR.

EF-2 AND EF-3EXHAUST FANS SHALL BE CONTROLLED BY THEIR RESPECTIVE LIGHT SWITCH.

EF-1:EXHAUST FAN SHALL BE INTERLOCKED WITH AHU-1 AND SHALL OPERATE AS FOLLOWS:EXHAUST FAN SHALL BE ENERGIZED WHEN AHU IS INDEXED FOR "OCCUPIED" MODE.WHEN AHU IS INDEXED FOR "UNOCCUPIED" MODE, THE EXHAUST FAN SHALL BE DE-ENERGIZED.

DUCTLESS SPLIT SYSTEM:

ON A RISE IN SPACE TEMPERATURE ABOVE THE THERMOSTAT SET POINT (76 F ADJ.),THE COMPRESSOR(S) SHALL BE ENERGIZED. ON A DROP IN TEMPERATURE THEREVERSE SHALL OCCUR.

CU-1 AND AC-1:COOLING MODE:

UPON DETECTION OF WATER IN THE CLOGGED PRIMARY LINE, THE ALARM WILLACTIVATE AN LED AND BUZZER, AND IT WILL DE-ENERGIZE THE CONDENSINGUNIT. WHEN THE ALARM CONDITION IS RESOLVED AND PROBES ARE DRIED, THESYSTEM WILL BE AUTOMATICALLY RESET TO NORMAL OPERATION.

CONDENSATE OVERFLOW DETECTION ALARM:

ON A DROP IN SPACE TEMPERATURE BELOW THE HEATING SET POINT (68 F ADJ) THEHEAT PUMP SHALL BE ENERGIZED. ON A CONTINUED DROP IN SPACE TEMPERATURE,THE ELECTRIC HEATING ELEMENT SHALL BE ENERGIZED. ON A RISE IN SPACETEMPERATURE ABOVE THE HEATING SET POINT (68 ADJ) THE REVERSE SHALL OCCUR.ON A DROP IN OUTDOOR TEMPERATURE BELOW 35 F (ADJ), THE HEAT PUMP SHALL BEDE-ENERGIZED AND THE ELECTRIC HEATING ELEMENT SHALL BE ENERGIZED TOMAINTAIN THE HEATING SETPOINT.

A DUCT MOUNTED SMOKE DETECTOR SHALL BE MOUNTED IN THE RETURN AIRDUCT OF AHU-1. UPON DETECTION OF PRODUCTS OF COMBUSTION AS SENSEDBY THE DETECTOR, THE DETECTOR SHALL SHUT DOWN THE FAN MOTOR ANDCONTROL SYSTEMS FOR THE RTU AND ACTIVATE A VISIBLE AND AUDIBLESUPERVISORY SIGNAL ON SYSTEM SENSOR SSK451 MULTI-SIGNALINGACCESSORY.
