SETPOINTS MAT SET 53_F 38 to 65_F;
increment by 1
Setpoi nt determines where the economizer will modulate the OA damper
to maintain the mixed air temperature.
LOW T LOCK 32_F ---45 to 80_F;
increment by 1
Setpoi nt determines outdoor temperature when the mechanical cooling
canno t be turned on. Commo nly referred to as the Compre sso r locko ut .
DRYBLB SET 63_F 48 to 80_F;
increment by 1
Setpoi nt determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.: at 63_F unit will economize at
62_F and below and not economize at 64_F and above. There is a
2_F deadband.
ENTH CURVE ES3 ES1, ES2, ES3, ES4, or
ES5
Enthalp y boundary “curve s” for econo m izi ng using si ng le enthalpy.
DCV SET 1100ppm 500 to 2000 ppm;
increment by 100
Displays only if CO

se nsor is conne c t e d. Setp oint for Demand Control
Ventilation of space. Above the setpoint, the OA dampers will modulate
open to bring in additional OA to maintain a space ppm level below the
setpoint.

sensor is connected. Used for Va (ventilation min
cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA, OA and MA). Va is
only set if DCV is used . This is the vent ilatio n for les s than maximum
occupancy of the space. In A UTO mode dampers controlled by CFM.

AUX2 I W SD/W or HP(O)/HP(B) In CONV mode: SD + Enables configurati on of shutdown (default); W =
Informs controller that system is in heating mode. In HP O/B mode:
HP(O) = energize heat pump on Cool (default); HP(B) = energize heat
pump on Heat.
FAN TYPE 2speed 1 speed/2 speed Sets the economizer controller for operation of 1 speed or 2 speed
supply fan.
