SYSTEM SETUP
(cont)
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 thermo-
stat 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.

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).

STG3 DLY
2.0h
0 min, 5 min, 15 min,
then 15 min intervals.
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
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. Re
q
uires all 3 RA, OA, and
MA sensors.
MAT T CAL
0.0°F
±2.5 F
SUPPLY AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
OAS T CAL
0.0°F
±2.5 F
OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
OA H CAL
0% RH
±10% RH
OUTSIDE AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration humidity sensor.
RA T CAL
0.0°F
±2.5 F
RETURN AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
RA H CAL
0% RH
±10% RH
RETURN AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration humidity sensor.
DA T CAL
0.0°F
±2.5 F
DISCHARGE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature sensor.
2SP FAN DELAY
5 Minutes
0 to 20 minutes in 1
minute increments
TIME DELAY ON SECOND STAGE ECONOMIZING
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.
CHECKOUT
DAMPER MINIMUM POSI-
TION
N/A
N/A
The checkout for the damper minimum position is based on the system.
DAMPER OPEN
N/A
N/A
Position damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make sure you
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 AUX1-O
N/A
N/A
Energizes the AUX output. If Aux setting is:
• NONE — not 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.
††
• SYS — 24 Vac out. Issues a system alarm
CONNECT EXH1
N/A
N/A
Closes the power exhaust fan 2 relay (EXH1)
