EXHAUST FAN SETPOINT AT HIGH SPEED (on 2 speed unit)
Setpoint for OA damper position when exhaust fan is powered by the
economizer
EXH2 L SET

0 to 100%;
Increment by 1
EXHAUST FAN STAGE 2 SETPOINT AT LOW SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer. Only used when AUX1—O is set to EHX2.
NOTE: Standard power exhaust kits have only 1 speed, therefore EXH2 is
not applicable

Increment by 1
EXHAUST FAN STAGE 2 SETPOINT AT HIGH SPEED
Setpoint for OA damper position when exhaust fan 1 is powered by the
economizer. Only used when AUX1—O is set to EHX2.
NOTE: Standard power exhaust kits have only 1 speed, therefore EXH2 is
not applicable
