SUPPLY AIR SETPOINT
Setpoint determines where the economizer will modulate the OA damper to
maintain the mixed air temperature.
LOW T LOCK 32F
-45 to 80 F;
increment by 1
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical cooling can-
not be turned on. Commonly referred to as the Compressor lockout.
DRYBLB SET 63F
48 to 80 F; increment
by 1
OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoint determines where the economizer will assume outdoor air tempera-
ture 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
ENTHALPY CHANGEOVER CURVE
Enthalpy boundary “curves” for economizing using single enthalpy.

500 to 2000 ppm;
increment by 100
DEMAND CONTROLLED VENTILATION
Displays only if CO
2
sensor is connected. Setpoint for Demand Controlled
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.
MIN POS 2.8 V 2 to 10 Vdc
VENTILATION MINIMUM POSITION
Displays ONLY if a CO
2
sensor is NOT connected.
VENTMAX
With 2-speed fan units
VENTMAX L (low speed fan)
and VENTMAX H (high
speed fan) settings are
required
2.8 V
2 to 10 Vdc
DCV MAXIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Vbz (ventilation max
cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA,OA, and MA). In AUTO
mode dampers controlled by CFM.
100 to 9990 cfm;
increment
by 10
If OA, MA, RA, and CO
2
sensors are connected and DCV CAL ENABLE is
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 CFM.
2 to 10 Vdc
With 2-speed fan units VENT L (low speed fan) and MIN POS H (high speed
fan) settings are required. Default for VENTMAX L is 3.2V and VENTMAX H
is 2.8V
VENTMIN
With 2-speed
fan units VENTMIN L (low
speed fan) and VENTMIN
H (high speed fan) set
2.25 V
2 to 10 Vdc or 100 to
9990 cfm increment
by 10
DCV MINIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Ba (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 ventilation for less than maximum occupancy of the
space. In AUTO mode dampers controlled by CFM.
100 to 9990 cfm;
increment
by 10
If OA, MA, RA, and CO
2
sensors are connected and DCV CAL ENABLE is
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 CFM.
2 to 10 Vdc
With 2-speed fan units VENTMIN L (low speed fan) and MIN POS H (high
speed fan) settings are required. Default for VENTMIN L is 3.2V and VENT-
MIN H is 2.8V

EXHAUST FAN STAGE 1 SETPOINT
Setpoint for OA damper position when exhaust fan 1 is powered by the econ-
omizer.
With 2-speed fan units Exh1 L (low speed fan) and Exh1 H (high speed fan)
settings are required. Default for Exh1 L is 65% and Exh1 H is 50%
EXH2 SET
With 2-speed fan units Exh2
L (low speed fan) and Exh2
H (high speed fan) settings
are required

EXHAUST FAN STAGE 2 SETPOINT
Setpoint for OA damper position when exhaust fan 2 is powered by the econ-
omizer. Only used when AUX1 O is set to EHX2.
With 2-speed fan units Exh2 L (low speed fan) and Exh2 H (high speed fan)
settings are required. Default for Exh2 L is 80% and Exh2 H is 75%
SYSTEM SETUP
INSTALL 01/01/10 N/A Display order = MM/DD/YY
Setting order = DD, MM, then YY.
UNITS DEG F F or C Sets economizer controller in degrees Fahrenheit or Celsius
EQUIPMENT CONV Conventional or HP CONV = conventional;
HP O/B = Enable Heat Pump mode. Use AUX2 I for Heat Pump input from
thermostat or controller.
See Menu Note 4.
AUX2 IN W SD/W or HP(O)/
HP(B)
In CONV mode:
SD + Enables configuration of shutdown (default);
W = Informs controller that system is in heating mode.
NOTE: If using 2-speed fan mode, you must program CONV mode for W.
Shutdown is not available in 2-speed fan mode. See Menu Note 4.
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energize heat pump on heat.
FAN SPEED 2 speed 1 speed/2 speed Sets the economizer controller for operation of 1 speed or 2 speed supply
fan.
NOTE: 2-speed fan option also needs Heat (W1) programmed in AUX 2 IN
See Menu Note 4.
