SEQUENCE OF OPERATION

DURING OPERATION THE GAS FIRED MAKE-UP AIR UNITS GAS HEATING SECTION SHALL MODULATE AS NECESSARY TO

MAINTAIN THE SPACE

TEMPERATURE SET POINT. WELDING HOOD AND DUST COLLECTOR EXHAUST FANS SHALL BE INTERLOCKED

TO START WHEN THE MAKE UP AIR UNIT IS STARTED. MAKE UP AIR UNIT AND EXHAUST FANS OPERATIONAL STATUS

SHALL BE IDENTIFIED AT THE DDC CONTROLLER. IF EITHER EXHAUST FAN FAILS TO INDICATE OPERATION THROUGH ITS

ASSOCIATED CURRENT TRANSFORMER (IY) WITHIN 30 SECS ( ADJ.) AFTER START INITIATION A FAILURE ALARM SHALL

BE INITIATED. THE MAKE UP AIR UNIT OPERATIONAL STATUS AND COMMON ALARM SHALL BE IDENTIFIED TO THE DDC

SYSTEM.

SEQUENCE OF OPERATION:

OCCUPIED/UNOCCUPIED MODE OF OPERATION IS DETERMINED BY THE AUTOMATED LOGIC DDC CONTROL SYSTEM.

OCCUPIED:

FURNACE "A" AND "B" ARE INTERLOCKED (TWINNED) FOR SIMULTANEOUS OPERATION AS A SINGLE UNIT.

WARM AIR FURNACE BLOWER OPERATES CONTINUOUSLY.

IN HEATING MODE OUTDOOR AIR DAMPER OPENS TO MINIMUM POSITION SPACE TEMPERATURE SENSOR MODULATES GAS

FIRED HEATING SECTION TO MAINTAIN DESIRED SPACE TEMPERATURE.

IN COOLING MODE ECONOMIZER IS FIRST STAGE OF COOLING PROVIDED THAT THE OUTDOOR AIR ENTHALPY IS EQUAL TO OR

LESS THAN RETURN AIR ENTHALPY OUTDOOR AIR AND RELIEF AIR DAMPERS ARE MODULATED BY THE BAS TO MAINTAIN

DESIRED SPACE TEMPERATURE. IF OUTDOOR AIR ENTHALPY IS GREATER THAN RETURN AIR ENTHALPY THE OUTDOOR AIR

DAMPERS RETURN TO MINIMUM POSITION AND THE MECHANICAL DX COOLING SYSTEM IS CYCLED TO MAINTAIN DESIRED SPACE

TEMPERATURE.

UNOCCUPIED:

OUTDOOR AIR DAMPER CLOSES, WARM AIR FURNACE BLOWER AND GAS FIRED HEATING SECTION CYCLE TO MAINTAIN SPACE

SET-BACK TEMPERATURE. DX COOLING SYSTEM IS LOCKED OUT.

GAS FIRED RADIANT TUBE HEATER SEQUENCE OF OPERATION

GAS FIRED RADIANT TUBE HEATERS ARE CONTROLLED BY THE BAS DDC CONTROL

SYSTEM. OCCUPIED/UNOCCUPIED MODES OF OPERATION ARE DETERMINED BY THE

DDC SYSTEM.

OCCUPIED:

SPACE TEMPERATURE SENSOR THROUGH THE DDC CYCLES RADIANT TUBE HEATERS

TO MAINTAIN DESIRED OCCUPIED SPACE TEMPERATURE.

UNOCCUPIED:

SPACE TEMPERATURE SENSOR THROUGH THE DDC CYCLES RADIANT TUBE HEATERS

TO MAINTAIN DESIRED SET-BACK TEMPERATURE.

GAS FIRED UNIT HEATER SEQUENCE OF OPERATION

GAS FIRED UNIT HEATERS ARE CONTROLLED BY THE BAS DDC CONTROL SYSTEM.

OCCUPIED/UNOCCUPIED MODES OF OPERATION ARE DETERMINED BY THE DDC

SYSTEM.

OCCUPIED:

SPACE TEMPERATURE SENSOR THROUGH THE DDC CYCLES UNIT HEATER FAN AND

GAS FIRED HEATING SECTION TO MAINTAIN DESIRED OCCUPIED SPACE TEMPERATURE.

UNOCCUPIED:

SPACE TEMPERATURE SENSOR THROUGH THE DDC CYCLES UNIT HEATER FAN AND

GAS FIRED HEATING SECTION TO MAINTAIN DESIRED SET-BACK TEMPERATURE.
