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.
FAN CFM
5000cfm
100 to 15000 cfm;
increment by 100
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 re
q
uired 2-speed values.

SUPPLY AIR TEMPERATURE LOW LIMIT
Temperature to achieve Freeze Protection (close damper and alarm if tem-
perature falls below setup value).

FREEZE PROTECTION DAMPER POSITION
Damper position when freeze protection is active (closed or MIN POS).

Up to 4 hrs or OFF
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 pro-
grammed for CLO. All other controls, e.g., fans, etc. will shut off.
DA LO ALM
45 F (7 C)
35 to 65 F; (2 to
18 C) Incremented
by 5 deg.
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.
DA HI ALM
80 F (27 C)
70 to 180 F; (21 to
82 C) Incremented
by 5 deg.
Used for alarm for when the DA air temperature is too high. Set upper 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. Re
q
uires all 3 RA, OA, and MA
sensors.
