DRY BULB ECONOMIZER - THE SUPPLY AIR TEMPERATURE SENSOR MODULATES THE

DAMPERS TO MAINTAIN THE REQUIRED SUPPLY AIR TEMPERATURE THROUGH A DRY

BULB ECONOMIZER ALGORITHM. WHEN THE OUTDOOR AIR TEMPERATURE IS ABOVE

72° F, THE OUTDOOR AIR DAMPER MOVES TO THE MINIMUM POSITION.

THESE UNITS ARE CONSTANT VOLUME, SINGLE ZONE UNITS, WHICH WILL OPERATE

CONTINUOUSLY WHENEVER THE BUILDING IS OCCUPIED. THE UNIT SHALL BE

PROVIDED WITH PROPRIETARY DDC CONTROLS TO ACCOMPLISH THE FOLLOWING

SEQUENCE. IN ADDITION, THE UNITS SHALL BE PROVIDED WITH AN INTERFACE

MODULE TO ALLOW MONITORING AND CONTROL FROM THE BAS.

SWITCH IS IN THE "AUTO" POSITION. WHEN THE FANS START, THE OUTDOOR, RELIEF,

HEATING AND COOLING - WHEN THE SUPPLY AIR TEMPERATURE SENSOR CANNOT

MAINTAIN THE REQUIRED SUPPLY AIR OR SPACE TEMPERATURE, MECHANICAL HEATING

COOLING MODE: WHEN THE SUPPLY AIR TEMPERATURE EXCEEDS ITS SETPOINT,

MECHANICAL COOLING WILL OCCUR. THE REFRIGERANT SOLENOID VALVE WILL OPEN,

ALLOWING REFRIGERANT TO THE COOLING COIL. IF AIRFLOW THROUGH THE AIR

WILL BE ENABLED. THE HIGHER PRESSURE IN THE SUCTION LINE WILL START THE

COOLING COMPRESSORS. A SUPPLY AIR TEMPERATURE SENSOR IN THE SUPPLY AIR

THIS UNIT IS A CONSTANT VOLUME AIR HANDLING UNIT WHICH WILL OPERATE CONTINUOUSLY

WHENEVER THE BUILDING IS OCCUPIED. THE UNIT SHALL BE PROVIDED WITH DDC CONTROLS TO

ACCOMPLISH THE FOLLOWING SEQUENCE.

FAN START - SUPPLY FAN SHALL START ON A SIGNAL FROM THE BUILDING AUTOMATION SYSTEM (BAS) WHEN THE FAN "HAND-OFF-AUTO" (H-O-A) SWITCH IS IN THE "AUTO" POSITION. WHEN THE

FAN STARTS THE OUTSIDE AIR DAMPER SHALL OPEN TO ITS MINIMUM POSITION, RETURN AIR

DAMPER SHALL GO TO ITS CORRESPONDING OPEN POSITION. RELIEF AIR DAMPER SHALL TRACK

RETURN AIR DAMPER, RELIEF FAN RELF-1 SHALL START AT ITS LOW SPEED AND RAMP UP TO

MAINTAIN MAXIMUM BUILDING PRESSURE DIFFERENTIAL OF 0.05 IN. WG (ADJUSTABLE)..

SUPPLY AIR TEMPERATURE - THE SUPPLY AIR TEMPERATURE WILL RESET, BASED ON OUTDOOR

AIR TEMPERATURE. THE SUPPLY AIR TEMPERATURE WILL RESET AS FOLLOWS:

OUTDOOR AIR TEMP. SUPPLY AIR TEMP.

57° F AND ABOVE 55°

32° F AND BELOW 60°

ENTHALPY ECONOMIZER - THE MIXED AIR TEMPERATURE SENSOR SHALL SEQUENCE THE O.A.,

RETURN AND RELIEF DAMPERS TO MAINTAIN THE REQUIRED SUPPLY AIR TEMPERATURE THROUGH AN ENTHALPY ECONOMIZER ALGORITHM. WHEN THE OUTDOOR AIR TEMPERATURE IS ABOVE 72° F, THE DAMPERS MOVE TO MINIMUM POSITION SET POINTS. DURING ECONOMIZER OPERATION, THE

ENERGY RECOVERY DAMPERS SHALL BE OPEN.
