NOTES
Setpoint determines where the economizer will modulate the
OA damper to maintain the mixed air temperature.
Setpoint determines outdoor temperature when the
mechanical cooling cannot be turned on. Commonly referred
to as the Compressor lockout.
Setpoint 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.
Enthalpy boundary "curves" for economizing using single
enthalpy.
Displays only if CO
sensor is connected. Setpoint for Demand
2
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.
Displays ONLY if a CO
sensor is NOT connected.
2
Displays only if a CO
sensor is connected. Used for Vbz
2
(ventilation max cfm) setpoint. Displays 2 to 10 V if <3 sensors
(RA,OA, and MA). In AUTO mode dampers controlled by
CFM.
N/A
N/A
Displays only if a CO
sensor is connected. Used for Ba
2
(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.
N/A

Only when AUX1 O = ERV
Setpoint for OA damper position when exhaust fan 1 is
powered by the economizer.
N/A
N/A
Setpoint for OA damper position when exhaust fan 2 is
powered by the economizer. Only used when AUX is set to
EHX2.

Display order = MM/DD/YY
Setting order = DD, MM, then YY.
Sets economizer controller in degrees Fahrenheit or Celsius
CONV = conventional; HP O/B = Enable Heat Pump mode.
Use AUX2 I for Heat Pump input from thermostat or
controller.
In CONV mode: SD + Enables configuration 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.
Sets the economizer controller for operation of 1 speed or 2
speed supply fan. (NOTE: for 3 speed units (48/50LC 14-26),
setpoint is a 2 speed.)
This is the capacity of the RTU. The value is found in the
Project Submittal documents for the specific RTU.
• NONE = not configured (output is not used)
• ERV = Energy Recovery Ventilator
• EXH2 = second damper position relay closure for second
exhaust fan
• SYS = use output as an alarm signal
When using a setback thermostat with occupancy out (24
vac), the 24 vac is input "INPUT" to the OCC terminal. If no
occupancy output from the thermostat then change program to
"ALWAYS" OR add a jumper from terminal R to OCC
terminal.
Resets all set points to factory defaults when set to YES. LCD
will briefly flash YES and change to NO but all parameters will
change to the factory default values.
