OAS T CAL 0.0
F ±2.5°F OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration tempera-
ture 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

Allows for the operator to adjust for an out of calibration tempera-
ture 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

ments
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. See Table 8.
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 — no action taken
• ERV — 24 vac out. Turns on or signals an ERV that the condi-
tions 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
MA T SENS ERR N/A N/A SUPPLY AIR TEMPERATURE SENSOR ERROR
Mixed air sensor has failed or become disconnected - check wir-
ing then replace sensor if the alarm continues.
CO2 SENS ERR N/A N/A CO
2
SENSOR ERROR
CO
2
sensor has failed, gone out of range or become discon-
nected - check wiring then replace sensor if the alarm continues.
OA SYLK T ERR N/A N/A OUTSIDE AIR S-BUS SENSOR ERROR
Outdoor air enthalpy sensor has failed or become disconnected
- check wiring then replace sensor if the alarm continues.
OA SYLK H ERR N/A N/A
RA SYLK T ERR N/A N/A RETURN AIR S-BUS SENSOR ERROR
Return air enthalpy sensor has failed or become disconnected -
check wiring then replace sensor if the alarm continues.
RA SYLK H ERR N/A N/A
DA SYLK T ERR N/A N/A DISCHARGE AIR S-BUS SENSOR ERROR
Discharge air sensor has failed or become disconnected - check
wiring then replace sensor if the alarm continues.
OA SENS T ERR N/A N/A OUTSIDE AIR TEMPERATURE SENSOR ERROR
Outdoor air temperature sensor has failed or become discon-
nected - check wiring then replace if the alarm continues.
ACT ERROR N/A N/A ACTUATOR ERROR
Actuator has failed or become disconnected - check for stall,
over voltage, under voltage and actuator count. Replace actua-
tor if damper is movable and supply voltage is between 21.6 V
and 26.4 V. Check actuator count on STATUS menu.
FREEZE ALARM N/A N/A Check if outdoor temperature is below the LOW Temp Lockout
on setpoint menu. Check if Mixed air temperature on STATUS
menu is below the Lo Setpoint on Advanced menu. When condi-
tions are back in normal range then the alarm will go away.
SHUTDOWN ACTIVE N/A N/A AUX2 IN is programmed for SHUTDOWN and 24 V has been
applied to AUX2 IN terminal.
