OUTSIDE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration outside air
temperature (OAT) sensor
OUTSIDE AIR HUMIDITY CALIBRATION
Allows for the operator to adjust for an out of calibration outside air enthalpy
sensor
RETURN AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration return air
temperature (RA) sensor
RETURN AIR HUMIDITY CALIBRATION
Allows for the operator to adjust for an out of calibration return air enthalpy
sensor
DISCHARGE AIR TEMPERATURE CALIBRATION
Allows for the operator to adjust for an out of calibration discharge air
temperature (DAT) sensor
TIME DELAY ON SECOND STAGE ECONOMIZING
While in the Economizing mode, this is the delay between thermostat Y2
call and Y1-O output to mechanical cooling stage, to allow high speed fan
operation to attempt to cool space first.
Positions OA damper to VMIN High Speed position
Positions OA damper to VMAX High Speed position
Position OA damper to the full open position.
Exhaust fan contacts enable during the DAMPER OPEN test. Make sure to
pause in the mode to allow exhaust contacts to energize due to the delay in
the system.
Positions damper to the fully closed position
Closes the Y1-O relay (Y1-O)
Closes the Y2-O relay (Y2-O)
Energizes the AUX1O output. If Aux setting is:
• NONE—no 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
MIXED AIR TEMPERATURE SENSOR ERROR
Mixed air sensor has failed or become disconnected - check wiring then
replace sensor if the alarm continues.
CO
SENSOR ERROR
2
CO
sensor has failed, gone out of range or become disconnected - check
2
wiring, then replace sensor if the alarm continues.
OUTSIDE AIR TEMPERATURE SENSOR ERROR
Outdoor-air temperature sensor has failed or become disconnected - check
wiring (OAT sensor connected at input terminals OAT), then replace if the
alarm continues.
OUTSIDE AIR ENTHALPY SENSOR ERROR
OAT sensor connected on S-bus.
DISCHARGE AIR TEMPERATURE SENSOR ERROR
When AUX1-O is set to SYS and there is any alarm (e.g., failed sensors,
etc.), the AUX1-O terminal has 24 vac out.
ACTUATOR VOLTAGE LOW
Voltage received by Actuator is below expected range.
ACTUATOR VOLTAGE HIGH
Voltage received by Actuator is over expected range.
ACTUATOR STALLED
Actuator stopped before achieving commanded position.
*Table 11 illustrates the complete hierarchy. Your menu parameters may
be different depending on your configuration.
NOTES:
1. Table 11 illustrates the complete hierarchy. Menu parameters may
be different depending on configuration. For example, none of the
DCV parameters appear for a system that does not have a DCV
(CO
) sensor.

2. When values are displayed, pressing and holding the
button causes the display to automatically increment.
3. ERV Operation: When in Cooling mode AND the conditions are
NOT OK for economizing - the ERV terminal will be energized. In
the Heating mode the ERV terminal will be energized when the OA
is below the ERV OAT set point in the set point menu.
