You can find the exact configuration of the DIP switches in the ROPEX Application Report calculated for your par-
ticular application.
If the secondary current I

is less than 30A, the secondary high-current wire must be laid twice (or several times)
through the PEX-W3 or PEX-W4 current transformer (
ROPEX Application Report).
5.11.2 Configuration of the rotary coding switch for the temperature range and alloy
The settings for a temperature coefficient of 780ppm (switch position 1 and 5) are only available on controllers
manufactured as of October 2003.
If the switch is set to "9" (as of October 2005), more temperature ranges and alloys can be selected by means of
the ROPEX visualization software (
see section 6.10 "Diagnostic interface/visualization software (as of October
