SYSTEM SETUP
INSTALL 01/01/10 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.

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 ther-
mostat 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.
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. Requires all 3 RA, OA,
and MA sensors.
