Input Devices And System; Functions - Trane IntelliPak SCWF 20 Installation, Operation And Maintenance Manual

Each binary output has a NO and NC contact with a
rating of two amps at 24 Vac. The five binary outputs
are factory preset as shown on the unit wiring diagram
(on the unit control panel door). However, these
outputs can be field defined in a variety of
configurations, assigning single or multiple diagnostics
to any output.
Table 43. GBAS analog input setpoints
Control Parameter
Occupied zone cooling setpoint (CV units only)
Unoccupied zone cooling setpoint (CV and VAV)
Occupied zone heating setpoint (CV units only)
Unoccupied zone heating setpoint (CV and VAV)
Supply air cooling setpoint (VAV units only)
Supply air hydronic heating setpoint (VAV units only)
Space static pressure setpoint
Supply air pressure setpoint (VAV units only)
Notes:
1. Input voltages less than 0.5 Vdc are considered as 0.5 Vdc input signal is lost, the setpoint will "clamp" to the low end of the setpoint scale. No
diagnostic will result from this condition.
2. Input voltages greater than 4.5 Vdc are considered to be 4.5 Vdc.
3. The actual measured voltage is displayed at the HI.
