two seconds and default parameters will be accepted. If parameters PS2 through PS4 need to be adjusted,
press the + σ button immediately to the next PS (see Commissioning Flowchart).
PS 2 – Input X1, X2 and X3
Select unit
Select main sensor X1
Enter X1 sensor calibration offset (Ni or Pt only)
Enter X1 active sensor range (0 to 10 Vdc only)
Select auxiliary sensor X2
Enter X2 sensor calibration offset (Ni or Pt only)
Enter X2 active sensor range (0 to 10 Vdc only)
Select sensor X3 (for Economizer sensor)
Enter X3 sensor calibration offset (Ni or Pt only)
Enter X3 active sensor range (0 to 10 Vdc only)
Select unit for X3 (for Independent control sensor)
Select X3 sensor
Enter X3 sensor calibration offset (Ni or Pt only)
Enter X3 active sensor range (0 to 10 Vdc only)

Siemens Industry, Inc.
There are five levels of parameter setting (PS) modes: PS1 through PS4, and a
setpoint mode. Each PS has a set of default parameters, which can be changed during
commissioning.
When powered the first time, the controller will proceed to PS1 with default
application 10. See below for commissioning steps.
