<br />I, AIR CONDITIONING UNITS (ACU)
<br />A. ALL AIR CONDITIONING UNITS, ROOF TOP ()?TU), AND SPLIT SYSTEM
<br />CONDENSER UNI i S (CU) AND AIR HANDLING UNITS (AHU), SHALL BE
<br />CONTROLLED BY A PROGRAMMABLE 24/7 SMART THERMOSTAT DEVICE.
<br />1.) DEVICE TO HAVE A 10' F (ADJ) DEADBAND, PROGRAMMABLE START AND
<br />STOP TIMES, 3 -POSITION ONIOFF/AUTO SELECTOR SWITCH AND A 2 HOUR
<br />MANUAL OVERRIDE,
<br />2. SUPPLY BANS (RTU & AHU)
<br />A. EACH UNIT'S SUPPLY AIR FANS ARE ENERGIZED AND THE OUTSIDE AIR (OA)
<br />DAMPERS MODULATE TO POSITION TO ADEQUATELY PRESSURIZE BUILDING.
<br />B. UNIT'S TEMPERATURE SENSOR, LOCATED IN THE RETURN ATR (RA) DUCT
<br />MtONITORS THE MIXED (MA), RA & CIA TEMPERATURE. IF THE ROOM
<br />TEMPERATURE IS NEST WITHIN 10°F DEGREES OF ROOM TEMPERATURE SET
<br />POINTS; UNIT WILL GO INTO HEATING OR COOLING MODE TO MEET THE
<br />DESIRED TEMPERATURE SET POINTS.
<br />C. EACH UNIT'S FAN WILL CONTINUE TO RUN FOR 2 MINUTES (ADJ) AFTER THE
<br />HEATING OR COOLING ROOM TEMPERATURE SET POINT IS MET.
<br />I). COOLING MODE:
<br />1) COMPRESSOR WILL BE ENERGIZER TO COOL THE AIR TO ROOM ATR
<br />TEMPERATURE,
<br />2) COMPRESSOR (S) WILL SHUT OFF WHEN MECHANICAL COOLING IS NO
<br />LONGER NEEDED,
<br />E. HEATING MODE -
<br />1) MEATTNG CONTROLS WILL ENERGIZE GAS BURNER IN FfPST STAGE AND IF
<br />NFCaFSSARY TO SECOND STAGE HEATING TO BRING AIR TEMPERATURE UP
<br />TO THE HEATING ROOM TEMPERATURE SET POINT,
<br />2) IF GAS HEATING IS NO LODGER NECESSARY, GAS BURNERS WILL SHUT
<br />OFF.
<br />3, MIXER AIR TEMPERATURE IS WITHIN If) F DEGREES OF ROOM TEMPERATURE:
<br />A. COMPRESSOR IS NOT ENERGIZED
<br />B. GAS BURNERS ARE NOT ENERGIZED.
<br />C. UNIT OPFRATES IN THF FCONOMIZEP MODE.
<br />1) ECONOMIZER MODE. WHEN OUTDOOR WEATHER CONDITIONS, AS SENSED
<br />BY UNIT MOUNTED CONTROLS, ARE BELOW ITS SETTING, AND FREE
<br />COOLING IS AVAILABLE, ECONOMIZER MODE SHALL BE ENABELED AND
<br />DAMPERS SHALL POSITION TO ENABLE 100% OA ENTERNG TETE BUILDING.
<br />EA DAMPERS TO MODULATE TO EXHAUS"f THE OA NOT BEING EXHAUSTED
<br />BY THE EXHAUST FANS (EFH-.1 & EF•X).
<br />2) WHEN THE OA SI -T -POINT IS BELOW 55°F (ADJ.), THE MECHANICAL
<br />COOLING SHALL BE DISABLED. THE ECONOMIZER CONTROL SHALL RESET
<br />0A DAMPERS TO THE MINIMUM RUN OA INTAKE POSITION AND ENERGIZE
<br />THE MECHANICAL COOLING WHEN THE OA SET POINT IS EXCEEDED.
<br />3) ADDITIONAL HIGH LIMIT SHUT OFF CONTROLS BELOW.
<br />A. CA TEMPERATURE > 75°F
<br />B. OA TEMPERATURE ;> RA TEMPERATURE
<br />C. (OA TEMPERATURE, OA RELATIVE HUMIDITY)>AIR
<br />E7, OA HUMIDITY > RA HUMIDITY

<br />G. NO FIXED ENTHALPY CONTROL,
<br />4. EXHAUST FANS
<br />A, RESTROOM EXHAUST FANS (EF) ARE TO BE STARTED BY AN OCCUPANCY
<br />SENSOR. WHEN THE OCCUPANT VACATES THE ROOM, THE FAN WILL REMAIN
<br />RUNNING FOR A MINIMUM OF 10 MINUTES (AD]).
<br />51 EXHAUST HOOD EXHAUST FAN (EFH-1)
<br />A. DAIS OVEN IS MANUALLY STARTED,
<br />B, EXHAUST FAN EFH-1 AUTOMATICALLY ENERGIZES AND STARTS RUNNING,
<br />C, ONCE EFH-1 IS UP TO SPEED, APPROXIMATELY 5 SECONDS (ADJ), THE SUPPLY
<br />AIR UNIT (SAU) INTRODUCING THE LARGEST AMOUNT OF OUTSIDE AIR (CIA)
<br />INTO THE BUILDING STARTS.
<br />1) ROOF TOP UNITS (RTU), AIR HANDLING UNITS (AHU) AND / OR MAKE-UP
<br />AIR UNITS (MAU) ARE CONSIDERED AS SUPPLY AIR UNITS (SAU),
<br />2) IF THERE IS A DEDICATED MAKE-UP AIR UNIT PROVIDING OA TO A SELF -
<br />COMPENSATING HOODS, THIS UNIT SHALL BE THE FIRST UNIT STARTED,
<br />D. AFTER A 5 SECOND (AD]) INTERVAL, THE SAU BRING IN THE NEXT LARGEST
<br />AMOUNT OF CIA INTO THE BUILDING STARTS.
<br />E. THIS PROCESS CONTINUES UNITL ALL OF THE SAU`S HAVE BEEN STARTED,
<br />6. WHEN GAS OVEN IS TURNED OFF:
<br />A. A51Y DEDICATED MAKF-UP AIR UNIT STOPS,
<br />B3 ON ALL SUPPLY AIR FANS OA DAMPERS CLOSE TO MINIMUM ALLOWED CIA
<br />POSITION AND THE EA DAMPER IS SET TO ALLOW SLIGHT BUILDING
<br />PRESSURIZATION.
<br />7. UNOCCUPIED MODE;
<br />A. VENT'IE.ATION AND ECONOMIZER DAMPERS BECOME FULLY CLOSET].
<br />B. THERMOSTAT SENDS SIGNAL TO UNITS TO OPERATE IN SETBACK MODE UNTIL
<br />NEXT OCCUPIED MODE CYCLE PER THERMOSTAT PROGRAMMING.
<br />C. DURING HEATING SEASON, THE UNITS TO BE EQUIPPED WITH CONTROLS TO
<br />AUTOMATICALLY RESTART AND TEMPORARILY OPERATE TO MAINTAIN A
<br />TEMPERATURE ABOVE 55°F.
<br />D. DURING COOLING SEASON, THE UNITS TO BE EQUIPPED WITH CONTROLS TO
<br />AUTOMATICALLY RESTART AND TEMPORARILY OPERATE TO MAINTAIN A
<br />TEMPERATURE BELOW B5°F.
<br />E, UNITS SHALL BE SEQUENCER TO MAINTAIN SPACE= TEMPERATURE AS FOLLOWS;
<br />1. THE LARGEST TONNAGE UNIT, OR AS THE SEQUENCE NUMBER IN THE AIR
<br />CONDITIONING UNIT SCHEDULES INDICATES, SHALL RUN TO MAINTAIN THE
<br />SPACE SETBACK TEMPERATURE,
<br />2. IF THE SPACE TEMPERATURE IS MEASURED AS 3-F ABOVE THE COOLING
<br />OP 3* BELOW THE HEATING SETBACK TEMPEREATURE, OR AS THE
<br />SEQUENCE NUMBER IN THE AIR CONDITIONING UNIT SCHEDULE
<br />INDICATES, SHALL START TO MAINTAIN THE SPACE SETBACK
<br />TEMPERATURE, WHEN THE TEMPERATURE DROPS TO 2oF BELOW THE
<br />SETBACK TEMPERATURE IN COOLING MODE OR ABOVE SETBACK
<br />TEMPERATURE IN HEATING MODE, THE SECOND UNIT SHALL. TURN OFF.
<br />8, AIR CONDITIONING UNIT MANUAL OVERRIDE MODE:
<br />A, VENTILATION AND ECONOMIZER DAMPERS BECOME POSITIONED AT THE
<br />MINIMUM OA SETTING.
<br />I3. THERMOSTAT SENDS SIGNAL TO UNIT TO OPERATE IN NORMAL TRIODE.
<br />G. iyANUAL OVERRIDE TIMER TO BE SET FOR A PERIOD OF 2 HOURS (AD].).
<br />9. EXHAUST HOOD FIRE SUPPRESSION SYSTEM:
<br />A. WHEN THE FXHAU.SI' HOOD FIRE SUPPRESSION SYSTEM IS ACTIVATED FANS IN
<br />ALL UNITS BRINGING OA INTO THE SPACE SHALL BE SHUT DOWN.
<br />B. FFH--1 IS FORCED ON TO FULL SPEED.
<br />10. SMOKE DETECTORS SEQUENCE OF OPERATION
<br />A. NOSY F;.MERGENCY OPERATION:
<br />1) THERMOSTATS, COMPRESSOR AND FANS RUN AS NORMAL.
<br />5SMOKE DETECTED IN SUPPLY OR RETURN:
<br />1.) SMOKE DETFCTOR GENERATE" VISIBLE ALERT SIGNS.
<br />2) SMOKE DETECTOR SENDS SIGNAL TO HVAC SYSTEM TO SHUT OFF.
<br />3) AIR CONDITIONING AND MAKE-UP AIR UNITS TO HAVE FANS AND
<br />COMPRESSORS DE -ENERGIZE,
