Configuration
Table 34 — Analog inputs
Note 1:
Trane’s Rover service tool uses the unit type to determine and download the proper default analog input
configuration.
Table 35 — Binary inputs
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
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
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.
