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. Requires
all 3 RA, OA, and MA sensors.
MAT T CAL

SUPPLY AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature
sensor.
OAS T CAL

±2.5°F
OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration temperature
sensor.
OA H CAL

±10% RH
OUTSIDE AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration humidity sensor.
RA T CAL

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
POSITION
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)
ALARMS
Alarms display only when they are active. The menu title “ALARMS(#)” includes the number of active alarms in parenthesis ( ). When
using SYLK bus sensors, “SYLK” will appear on the screen, and when using 20k OA temperature sensors, “SENS T” will appear on the
screen
