THE ALARM SHALL <br />AUTOMATICALLY CLEAR WHEN THE FAN STATUS MATCHES THE COMMAND FOR 1 MINUTE. <br />• FAN IN HAND: FAN IS COMMANDED OFF, BUT THE STATUS IS ON FOR 1 MINUTE. THE ALARM SHALL <br />AUTOMATICALLY CLEAR WHEN THE FAN STATUS MATCHES THE COMMAND FOR 1 MINUTE. <br />VRF DUCTED FAN COIL UNIT: <br />CONTROL OF THE VRF FAN COIL UNITS SHALL BE THROUGH THE VRF CONTROL SYSTEM. THIS SYSTEM WILL BE <br />INTEGRATED INTO THE BAS VIA BACNET INTERFACE. UNLESS OTHERWISE NOTED, ALL SETPOINTS AND TIME <br />DELAYS SHALL BE ADJUSTABLE <br />RUN CONDITIONS - SCHEDULED: <br />THE UNIT SHALL RUN ACCORDING TO A USER DEFINABLE TIME SCHEDULE IN THE FOLLOWING MODES: <br />OCCUPIED MODE: <br />• A 75°F COOLING SETPOINT. <br />• A 70°F HEATING SETPOINT. <br />UNOCCUPIED MODE: <br />• A 85°F COOLING SETPOINT. <br />• A 55°F HEATING SETPOINT. <br />ALARMS SHALL BE PROVIDED AS FOLLOWS: <br />· HIGH ZONE TEMPERATURE: THE ZONE TEMPERATURE IS GREATER THAN THE COOLING SETPOINT BY 5°F FOR 10 <br />MINUTES. THE ALARM SHALL AUTOMATICALLY CLEAR WHEN THE ZONE TEMPERATURE RETURNS BELOW THE <br />ALARM THRESHOLD FOR 6 MINUTES. <br />· LOW ZONE TEMPERATURE: THE ZONE TEMPERATURE IS LESS THAN THE HEATING SETPOINT BY 5°F FOR 10 <br />MINUTES. THE ALARM SHALL AUTOMATICALLY CLEAR WHEN THE ZONE TEMPERATURE RETURNS ABOVE THE <br />ALARM THRESHOLD FOR 6 MINUTES. <br />ZONE SETPOINT ADJUST: <br />THE OCCUPANT SHALL BE ABLE TO ADJUST THE ZONE TEMPERATURE HEATING AND COOLING SETPOINTS AT THE <br />ZONE SENSOR. THE RANGE OF ADJUSTMENT SHALL BE +/- 2°F. <br />ZONE UNOCCUPIED OVERRIDE: <br />A TIMED LOCAL OVERRIDE CONTROL SHALL ALLOW AN OCCUPANT TO OVERRIDE THE SCHEDULE AND PLACE THE <br />UNIT INTO AN OCCUPIED MODE FOR A 30 MINUTE (ADJ.) PERIOD OF TIME. AT THE EXPIRATION OF THIS TIME, <br />CONTROL OF THE UNIT SHALL AUTOMATICALLY RETURN TO THE NORMAL SCHEDULE. <br />SUPPLY FAN: <br />THE SUPPLY FAN SHALL RUN ANYTIME THE UNIT IS COMMANDED TO RUN, UNLESS SHUTDOWN ON SAFETIES. TO <br />PREVENT SHORT CYCLING, THE SUPPLY FAN SHALL BE SUBJECT TO THE FACTORY MINIMUM RUNTIME SAFETIES. <br />COOLING ENABLE: <br />THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND ENABLE COOLING TO MAINTAIN ITS ZONE <br />COOLING SETPOINT. <br />COOLING SHALL BE ENABLED WHENEVER: <br />· THE ZONE TEMPERATURE IS ABOVE THE COOLING SETPOINT. <br />· AND THE SUPPLY FAN STATUS IS ON. <br />HEATING ENABLE: <br />THE CONTROLLER SHALL MEASURE THE ZONE TEMPERATURE AND ENABLE HEATING TO MAINTAIN THE ZONE <br />HEATING SETPOINT. <br />HEATING SHALL BE ENABLED WHENEVER: <br />· THE ZONE TEMPERATURE IS BELOW THE HEATING SETPOINT. <br />· AND THE SUPPLY FAN STATUS IS ON. <br />THRU FC <br />8 <br />11870 Pierce Street, Suite 160 <br />Riverside, California 92505 <br />951.299.4160 www.tk1sc.com <br />C O L L A B O R A T I V E <br />THIS DOCUMENT CONTAINS INFORMATION PROPRIETARY TO SVA ARCHITECTS <br />INC.
