Temp to activate Freeze Protection (close
damper and alarm if temp falls below setup
value). Always 3F below MA Setpoint.
FREEZE POS CLO CLO MIN Damper position when freeze protection is
active (closed or MIN POS).
CO2 ZERO 0ppm 0 to 500

CO2 ppm level to match CO2 sensor start
level.
CO2 SPAN 2000pp

1000 to
3000 ppm;
increment by

CO2 ppm span to match CO2 sensor.
STG3 DLY 2.0h 0 min, 5 min,

intervals. Up
to 4h or OFF
Delay after stage 2 for cool has been active.
Turns on 2nd stage of mechanical cooling
when economizer is 1st stage and mechanical
cooling is 2nd stage. Allows three stages of
cooling, 1 economizer and 2 mechanical. OFF
= no Stage 3 cooling.
SD DMPR POS CLO CLO OPN Indicates shutdown signal from space
thermostat or unitary controller. When
controller receives 24 Vac input on the SD
terminal in conventional mode, the OA damper
will open if programmed for OPN and OA
damper will close if programmed for CLO. All
other controls, e.g., fans, etc. will shut off.
DCVCAL ENA MAN MAN
(manual)
AUTO
Turns on the DCV automatic control of the
dampers. Resets ventilation based on the RA,
OA and MA sensor conditions. Requires all
sensors (RA, OA, MA and CO2). This
operation is not operable with a 2-speed fan
unit.
MAT T CAL 0.0 F° +/-2.5F° Allows for the operator to adjust for an out of
calibration temperature sensor
OA T CAL 0.0F° +/-2.5F° Allows for the operator to adjust for an out of
calibration temperature sensor
OA H CAL 0% RH +/-10% RH Allows for the operator to adjust for an out of
calibration humidity sensor
RA T CAL 0.0F° +/-2.5F° Allows for the operator to adjust for an out of
calibration temperature sensor
RA H CAL 0% RH +/-10% RH Allows for the operator to adjust for an out of
calibration humidity sensor
DA T CAL 0.0 F° +/-2.5F° Allows for the operator to adjust for an out of
calibration temperature sensor
2SP FAN DELAY 5

increments
When in economizing mode this is the delay for
the high speed fan to try to satisfy the call for
second stage cooling before the first stage
mechanical cooling is enabled.
