  • Page 14 Parameter settings Threshold value setpoint using a communications object: Beforehand, enter how the threshold value will be received from the bus. Basically, a new value can be received, or simply a command to increase or decrease. During initial commissioning, a threshold value must be defined which will be valid un- til the first call with of a new threshold value.

  • Page 17 Parameter settings Heating control level (1./2. level) If a heating control mode is configured, one or two setting sections for the heating lev- els are displayed. In the first level, heating is controlled by a PI controller which allows to either enter con- trol parameters or select predetermined applications.
