SETUP (CONT)
MAT T CAL 0.0°F (or °C) ±2.5°F
(±1.4°C) SUPPLY AIR TEMPERATURE CALIBRATION
Allows the operator to adjust for an out of calibration supply air tempera-
ture (SAT) sensor.
OAS T CAL 0.0°F (or °C) ±2.5°F
(±1.4°C) OUTSIDE AIR TEMPERATURE CALIBRATION
Allows the operator to adjust for an out of calibration outside air tempera-
ture (OAT) sensor.
OA H CAL 0% RH ±10% RH OUTSIDE AIR HUMIDITY CALIBRATION
Allows for operator to adjust for an out of calibration outside air enthalpy
sensor.
RA T CAL 0.0°F (or °C) ±2.5°F
(±1.4°C) RETURN AIR TEMPERATURE CALIBRATION
Allows the operator to adjust for an out of calibration return air
temperature (RA) sensor
RA H CAL 0% RH ±10% RH RETURN AIR HUMIDITY CALIBRATION
Allows the operator to adjust for an out of calibration return air enthalpy
sensor.
DA T CAL 0.0°F (or °C) ±2.5°F
(±1.4°C) DISCHARGE AIR TEMPERATURE CALIBRATION
Allows the operator to adjust for an out of calibration discharge air tem-
perature (DAT) sensor
2SP FAN DELAY 5 Minutes 0 to 20 minutes in 1
minute increments TIME DELAY ON 2nd 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 mechani-
cal 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 9.
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). See Caution on page 46.
CONNECT Y2–O N/A N/A Closes the Y2-O relay (Y2-O). See Caution on page 46.
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 good for ERV operation.
††
• SYS — 24 Vac out. Issues a system alarm
CONNECT EXH1 N/A N/A Closes the power exhaust fan 1 relay (EXH1)
ALARMS
Alarms display only when they are active. The menu title “ALARMS(#)” includes the number of active alarms in parenthesis ( ). When using S-bus sen-
sors, “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
Supply air sensor has failed or become disconnected — check wiring then
replace sensor if the alarm continues.
CO2 SENS ERR N/A N/A CO

sensor has failed, gone out of range or become disconnected - 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 disconnected —
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 volt-
age, under voltage and actuator count. Replace actuator if damper is
movable and supply voltage is between 21.6 V and 26.4 V. Check actua-
tor 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 setup menu. When conditions are back in normal
range the alarm will go away.
