with ISO 11898 must be used for bus systems with 120 Ω nominal impedance. Only
when such cables are used can a high level of data transfer security be guaranteed.

The servo drive of the KHS CoolFlow cold water regulating
valve automatically carries out an initialisation run when the
„KHS CoolFlow 230V" valve is selected in the device settings.
This run covers the complete path of the servo drive. For
correct initialisation, the servo drive must be mounted on the
valve. The valve and the servo drive must be installed.
