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.
FAN CFM 5000cfm
100 to 15000 cfm;

UNIT DESIGN AIRFLOW (CFM)
Enter only if using DCVAL ENA = AUTO
The value is found on the nameplate label for the specific unit.
AUX1 OUT NONE
NONE
ERV
EXH2
SYS
Select OUTPUT for AUX1 O relay
• 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
OCC INPUT
INPUT or
ALWAYS
OCCUPIED MODE BY EXTERNAL 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.
FACTORY DEFAULT NO NO or YES
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.
NOTE: RECHECK AUX2 IN and FANTYPE for required 2-speed
values.

COOLING STAGE 3 DELAY
Delay after stage 2 cool has been active. Turns on second
stage
of cooling when economizer is first
stage and mechanical
cooling is second
stage. Allows three stages of cooling, 1
economizer and 2 mechanical. OFF = no Stage 3 cooling
SD DMPR POS CLO CLO or 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.

Used for alarm for when the DA air temperature is too low. Set
lower range of alarm, Below this temperature the alarm will show
on the display.

70°F to 180°F;
(21°C to 82°C)
Incremented by

Used for alarm for when the DA air temperature is too high. Set
higher range of alarm, Above this temperature the alarm will
show on the display.
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.
