ON A START COMMAND THE OUTSIDE AIR AND RETURN DAMPERS SHALL GO TO THEIR NORMAL <br />OPEN POSITIONS. AFTER A 20 SECOND (ADJUSTABLE) DELAY, THE EVAPORATOR FAN SHALL <br />START AND RUN CONTINUOUSLY. <br />2. A FLOW SWITCH IN THE FAN DISCHARGE SHALL PROVE AIRFLOW. IF NO FLOW IS INDICATED, <br />AN ALARM SIGNAL SHALL BE SENT TO THE BAS. <br />3. A SPACE TEMPERATURE SENSOR (T-1) SHALL BE USED TO SEQUENCE HEATING AND COOLING. <br />4. IN THE COOLING MODE THE SPACE TEMPERATURE SENSOR (T-1) SHALL STAGE THE COMPRESSORS <br />TO MAINTAIN SETPOINT. HOT GAS BYPASS SYSTEM SHALL CONTROL SPACE HUMIDITY AND VARYING <br />LOAD CONDITIONS. <br />5. IN THE HEATING MODE THE SPACE TEMPERATURE SENSOR (T-1) SHALL MODULATE COMPRESSORS TO <br />MAINTAIN SETPOINT. <br />6. WHEN THE SMOKE DETECTOR (SD-1 ) DETECTS PARTICLES OF COMBUSTION, THE UNIT <br />SHALL NOT SHUT DOWN, BUT AN ALARM CONDITION SHALL BE INDICATED. <br />7. WHEN THE FIRE ALARM SYSTEMS INDICATES AN ALARM THE UNIT SHALL NOT SHUT DOWN BUT AN <br />ALARM CONDITION SHALL BE INDICATED. <br />8. THE EXHAUST FAN EF-1 SHALL START AND RUN CONTINUOUSLY. A FLOWSWITCH IN THE FAN SHALL <br />PROVE AIRFLOW. IF NO FLOW IS INDICATED, AN ALARM SIGNAL SHALL BE SENT TO THE BAS. <br />ROOFTOP UNIT -ELECTRIC - RTU-1 AND EXHAUST FAN EF-1 <br />FULL OPEN POSITION: <br />THE MAXIMUM POSSIBLE OPEN POSITION OF A VALVE OR DAMPER. <br />FULL CLOSED POSITION: <br />THE MINIMUM POSSIBLE OR SHUT OFF POSITION OF A VALVE OR DAMPER. <br />MAXIMUM OPEN POSITION: <br />THE MAXIMUM OPEN POSITION REQUIRED FOR A VALVE OR DAMPER AS INDICATED <br />BY THE SCHEDULED OPERATING CAPACITY OR BY THE CONTROL SEQUENCE. <br />MINIMUM OPEN POSITION: <br />THE MINIMUM OPEN POSITION REQUIRED FOR A VALVE OR DAMPER AS INDICATED <br />BY THE SCHEDULED OPERATING CAPACITY OR BY THE CONTROL SEQUENCE. <br />SET POINT: <br />THE DESIRED OPERATING POINT FOR A PARAMETER, AS DETERMINED BY MANUAL INPUT <br />OR AUTOMATICALLY IN ACCORDANCE WITH THE CONTROL SEQUENCE. <br />FIELD DETERMINED SET POINT: <br />THE DESIRED OPERATING POINT FOR A PARAMETER, AS DETERMINED BY FIELD CONDITIONS, <br />SUCH AS ACTUAL OPERATING POINTS, ACTUAL PRESSURE DROPS, OR OTHER FIELD DETERMINED <br />VALUES. <br />BAS: <br />BUILDING AUTOMATION SYSTEM. <br />GENERAL NOTES: <br />1. THESE GENERAL NOTES APPLY TO ALL CONTROL DIAGRAMS AND SEQUENCES AS WELL AS <br />ALL WORK RELATED TO THE HVAC CONTROLS INDICATED ON OTHER M-SERIES DRAWINGS. <br />2. THE DIAGRAMS, POINT LISTS AND CONTROL SEQUENCES DESCRIBE THE REQUIRED SEQUENTIAL OPERATIONS <br />OF SYSTEMS AND MAJOR COMPONENTS. THEY DO NOT DEFINE IN DETAIL THE OPERATION OF MINOR <br />COMPONENTS, RELAYS, SWITCHES OR OTHER SMALL DEVICES REQUIRED FOR THE PROPER FUNCTIONING <br />OF THE CONTROL SYSTEM. INCORPORATE ALL SUCH ITEMS IN ORDER TO PROVIDE PROPER OPERATION OF <br />CONTROL COMPONENTS AND EQUIPMENT. <br />3. THE SEQUENCES OF OPERATION DESCRIBE CHANGES IN CONTROL FUNCTIONS AS OPERATING CONDITIONS <br />VARY IN A PARTICULAR MANNER, SUCH AS RISING ROOM TEMPERATURE. UNLESS OTHERWISE STATED, THE <br />SEQUENCES SHALL BE REVERSED WHEN THE OPERATING CONDITIONS REVERSE, SUCH AS WHEN THE <br />RISING ROOM TEMPERATURE BEGINS TO FALL. <br />4. CONTROL DEVICE SET POINTS SHALL BE MANUALLY ADJUSTABLE OVER THEIR ENTIRE CONTROL RANGE. SET <br />POINTS MAY BE FACTORY SET, BUT SHALL BE FIELD ADJUSTABLE. SPECIFIED SET POINTS SHALL TAKE <br />PRECEDENCE OVER FACTORY SETTINGS. <br />5. WHERE THE CONTROL SEQUENCE INDICATES AN AUTOMATIC RESET PROCEDURE, THE SET POINT SHALL <br />INDICATE THE NORMAL START-UP CONDITION. <br />6. TEMPERATURE, AIR FLOWS, PRESSURES AND SIMILAR DATA SHOWN ON CONTROL DIAGRAMS ARE NOMINAL <br />VALUES SO THAT TYPICAL DIAGRAMS MAY BE USED. SEE EQUIPMENT SCHEDULES FOR DATA DIRECTLY <br />APPLICABLE TO INDIVIDUAL EQUIPMENT ITEMS. WHERE NOTED, VALUES SHALL BE FIELD MEASURED <br />OR CALCULATED IN ACCORDANCE WITH THE PROCEDURE INDICATED. <br />7. LOCATE THERMOSTATS AND OTHER DEVICES REQUIRING OCCUPANT MONITORING OR ADJUSTMENT <br />AT AN ELEVATION 4'4' ABOVE FINISHED FLOOR, IN ACCORDANCE WITH ADA REGULATIONS. <br />SENSORS WITH NO EXTERNAL ADJUSTMENTS SHALL BE MOUNTED 4'-6" ABOVE FINISHED FLOOR. <br />8. ALL WORK SHALL BE COORDINATED WITH ALL TRADES INVOLVED. INTERFACE EQUIPMENT AND WIRING <br />SHALL BE PROVIDED AT NO ADDITIONAL COST TO THE OWNER. <br />9. CEILING ACCESS PANELS AND DUCT ACCESS PANELS SHALL BE PROVIDED, WHERE REQUIRED, TO SERVICE <br />DAMPERS, HEATERS, VALVES AND OTHER CONCEALED EQUIPMENT. <br />10. CONTROL WIRE AND CONDUIT SHALL BE SUPPLIED AND INSTALLED UNDER DIVISION 15, AND SHALL COMPLY <br />WITH N.E.0 AND DIVISION 16 SPECIFICATIONS. <br />11. DIVISION 16 SHALL PROVIDE POWER WIRING AND CONDUIT FROM POWER PANELS TO CONTROL SYSTEM <br />EQUIPMENT. DIVISION 16 SHALL PROVIDE THE BREAKER. COORDINATE POWER REQUIREMENTS WITH DIVISION 16. <br />12. CONTROL SYSTEMS SUPPLIER SHALL WIRE FROM DRY CONTACTS IN FIRE ALARM PANEL AS REQUIRED FOR <br />INTERFACE BETWEEN FIRE ALARM SYSTEM AND HVAC CONTROL SYSTEMS. <br />13.
