VAV CONTROL SEQUENCENORMAL OPERATION

1. VAV SUPPLY TERMINAL SHALL MODULATE BETWEEN MAXIMUM AND MINIMUM AIR VOLUMES TO MAINTAIN SPACE TEMPERATURE. AT MINIMUM AIR VOLUME (40%), IF SPACETEMPERATURE FALLS BELOW SETPOINT, THE REHEAT COIL VALVE SHALL MODULATE OPEN AS REQUIRED TO RAISE SPACE TEMPERATURE TO SETPOINT. THE VAV TERMINALAND REHEAT COIL VALVE SHALL BE CONTROLLED FROM THE AIR TEMPERATURE SENSOR DOWNSTREAM FROM THE REHEAT COIL, WHICH SHALL HAVE ITS SETPOINT RESETFROM THE ROOM TEMPERATURE SENSOR.

2. THE TEMPERATURE OF THE SUPPLY AIR, ALONG WITH THE RESPECTIVE AIR VOLUME, SHALL BE MEASURED AND INPUT INTO THE CONTROLLER. THE CONTROLLER SHALLADJUST THE HEATING VALVE ON THE SUPPLY AIR REHEAT COIL, BASED ON THOSE INPUTS AS WELL AS AN INPUT FROM A SPACE TEMPERATURE SENSOR. IF THE DISCHARGEAIR TEMPERATURE REQUIRED TO SATISFY THE SPACE TEMPERATURE EXCEEDS DESIGN, RESET THE HEATING CFM (OR MIN SUPPLY CFM) UP TO A LARGER CFM (60%) UNTILTHE DISCHARGE TEMPERATURE IS LESS THAN THE DESIGN DISCHARGE TEMPERATURE SETPOINT. MAXIMUM DESIGN DISCHARGE AIR TEMPERATURE SHALL BE 95°F.

3. FOR ROOMS THAT HAVE MULTIPLE ZONES, THE VAV TERMINAL CONTROLS SHALL BE TIED TOGETHER IN ORDER TO PREVENT SIMULTANEOUS HEATING AND COOLING OF THESAME SPACE.

UNOCCUPIED ROOM OPERATION

1. THE UNOCCUPIED MODE OF OPERATION FOR MEETING ROOMS IS DETERMINED BY OCCUPANCY SENSOR. DURING THIS MODE OF UNOCCUPIED OPERATION THE SPACETEMPERATURE COOLING AND HEATING SETPOINTS SHALL BE RESET BY AN ADJUSTABLE VALUE THAT CHANGES FOR OCCUPIED PERIODS AND UNOCCUPIED PERIODS. THEDESIGN SHOULD START WITH A ±1° F DURING OCCUPIED PERIODS AND ±3° F DURING UNOCCUPIED PERIODS. AS THE SPACE REQUIRES MORE AIR FLOW TO MAINTAIN THECOOLING TEMPERATURE SETPOINT, THE SUPPLY AIR TERMINALS SHALL MODULATE, ENSURING THAT THE DESIGN IS MAINTAINED. AT ALL TIMES THE COOLING MAXIMUM CFMVALUE SHALL BE POSSIBLE, SHOULD SPACE SENSIBLE COOLING LOAD REQUIRE THIS VALUE. UPON A RETURN TO OCCUPANCY SENSED BY THE OCCUPANCY SENSOR, ATEMPERATURE CONTROL ALGORITHM SHALL CONTROL THE TERMINALS AND REHEAT TO MINIMIZE CHANGES IN SPACE TEMPERATURE TO LESS THAN ±1° F.

UNOCCUPIED BUILDING OPERATION

1. THE UNOCCUPIED MODE OF OPERATION IS DETERMINED BY THE BUILDING SCHEDULE. SPACE TEMPERATURE SHALL BE MONITORED BY THE BAS. THE SPACES SHALLINCREASE TO A MAXIMUM OF 80° F SUMMER OR DECREASE A MINIMUM OF 55° F WINTER.

2. WHEN THREE(3) OR MORE ZONES REACH MAXIMUM OR MINIMUM SPACE SET POINT, PROVIDE SIGNAL TO BAS SYSTEM TO RESTART ROOFTOP UNIT (RTU) AND RESET VAVCONTROL TO MAXIMUM COOLING OR MAXIMUM REHEAT TO RECOVERY SPACE TEMPERATURE BACK TO 70° F AND THEN SHUT DOWN RTU.
