    Control parameters The control parameters have been optimized at the factory for operation as a bath thermostat (with water as the heat transfer liquid) with internal control. The standard parameters are already set as default also for the thermostatic control of external applications with external control. Depending on the application, the configuration can be adapted from case to case as required.

  • Page 99: External Control Variable

    External control variable The setting options illustrated in this section are only possible with a connected external temperature sensor or with an existing module (as activated as control variable in Section C) for reading in the actual temperature. The control system for external actual values is realized as a two-stage cascade controller to improve the response to setpoint changes.
