Configuration
Table 34 — Analog inputs
Analog input Function
(Note 1)
IN 1 Space temperature sensor
IN 2 Hardwired setpoint
IN 3 Fan mode switch
IN 4 Discharge air temp
IN 5 Outdoor air temp
IN 6 Mixed air temp
Duct static Duct static pressure
Note 1: Trane's Rover service tool uses the unit type to determine and download the proper default analog input
configuration.

Not used
Note 1: Trane's Rover service tool uses the unit type to determine and download the proper default binary input
configuration.
Note 2: When the supply fan is off, the state of the fan status device is its normal state. For example, if the fan status
switch (end device) is normally open when the fan is off, the controller should be configured for a normally open fan
status input.
Note 3: When the supply fan is off, the state of the filter status device is its normal state. For example, if the filter status
switch (end device) is normally closed when the fan is off, the controller should be configured for a normally closed
filter status input.
Table 36 — Outdoor air damper
Parameter
Occupied outdoor damper minimum position
Occupied standby damper minimum position (Note 1)
Economizer enable temperature (dry bulb)
Low ambient damper lock out temperature (Note 2)
Outdoor air damper open time (Note 3)
Note 1: Occupied standby minimum damper position only applies to space temperature control operation.
Note 2: This is the outdoor air temperature below which the outdoor air damper will always be closed.
Note 3: Adjustable open time for the outdoor air damper to open from 0% to minimum position.
Table 37 — Exhaust fan or damper
Parameter
Exhaust fan start setpoint (Note 1)
Exhaust fan stop differential (Note 1)
Note 1: The exhaust fan is energized when the outdoor air damper is equal to or greater than the exhaust fan start
setpoint. The exhaust fan is turned off when the outdoor air damper is less than the exhaust fan start setpoint minus
the exhaust fan stop differential.
