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
Always set to CONV even for heat pump.
AUX2 I
W
W required for
2-speed mode
Always set to W.
FAN TYPE
2-speed
1-speed/2-speed
Sets the economizer controller to the number of unit fan speeds.
Fan Type options:
1 Speed units
2 speed units
*2 speed units: 1 for heat and 1 for cool
*3 speed units: 1 for heat and 2 for cool
* These Fan Type (speed) settings are for future use only. Do not use for 3-speed LC units.

NONE
ERV
EXH2
SYS
• NONE = not configured (output is not used)
• ERV = Energy Recovery Ventilation
• EXH2 = second damper position relay closure for second exhaust fan
• SYS = use output as an alarm signal

STG3 DLY
2.0h
0 min, 5 min, 15 min,
then 15 min intervals.
Up to 4h or OFF
COOLING STAGE 3 DELAY
Delay after stage 2 for cool has been active. Turns on second stage of cooling when
economizer is first stage and mechanical cooling is second. Allows three stages of
cooling, 1 economizer and 2 mechanical.
OFF = no Stage 3 cooling
SD DMPR POS
CLO
CLO or OPN
Function NOT AVAILABLE with 2-speed mode
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 3 RA, OA, and MA sensors.
For single speed units only.
MAT T CAL
0.0°F (or °C)
±2.5°F (±1.4°C)
MIXED AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration mixed air temperature (MAT)
sensor.
OA T CAL
0.0°F (or °C)
±2.5°F (±1.4°C)
OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration outside air temperature
(OAT) sensor.
OA H CAL
0% RH
±10% RH
OUTSIDE AIR HUMIDITY CALIBRATION
Allows for the operator to adjust for an out of calibration outside air enthalpy sensor.
RA T CAL
2.0°F (or °C)
±2.5°F (±1.4°C)
RETURN AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration return air temperature (RA)
sensor.
RA H CAL
0% RH
±10% RH
RETURN AIR HUMIDITY CALIBRATION
Allows for the operator to adjust for an out of calibration return air enthalpy sensor.
DA T CAL
0.0°F (or °C)
±2.5°F (±1.4°C)
DISCHARGE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration discharge air temperature
(DAT) sensor.
2SP FAN DELAY
5 minutes
0 to 20 minutes in 1
minute increments
TIME DELAY ON SECOND STAGE ECONOMIZING
While in the Economizing mode, this is the delay between thermostat Y2
call and Y1-O output to mechanical cooling stage, to allow high speed fan
operation to attempt to cool space first.
CHECKOUT
DAMPER VMIN-HS
n/a
n/a
Positions OA damper to VMIN High Speed position
DAMPER VMAX-HS
n/a
n/a
Positions OA damper to VMAX High Speed position
DAMPER OPEN
n/a
n/a
Position OA damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make sure to pause in
the mode to allow exhaust contacts to energize due to the delay in the system.
DAMPER CLOSE
n/a
n/a
Positions damper to the fully closed position.
CONNECT
Y1-O
n/a
n/a
Closes the Y1-O relay (Y1-O).
CONNECT
Y2-O
n/a
n/a
Closes the Y2-O relay (Y2-O).
CONNECT AUX1O
n/a
n/a
Energizes the AUX1O output. If Aux setting is:
• NONE—no action taken
• ERV—24 vac out. Turns on or signals an ERV that the conditions
are not good for economizing but are for ERV operation.
3
• SYS—24 vac out. Issues a system alarm.
