The controller operates in a periodic manner over a cycle, and in each period it maintains the output to the On value for a time proportional to the value of the control variable.

  • Page 21: Setpoint Management

    Applicatio Manual Universal Interface 4 DIN/NTC EK- CG2-TP 7.4 Setpoint management The device is not equipped with a local interface to control the integrated room thermostat, therefore the temperature setpoint modifications need to be performed by another KNX device (supervisor) and sent to this device through communication objects.

  • Page 22: Operating Modes

    In mode 1, the switch over command is issued through KNX bus and therefore it is performed by a different KNX device, e.g. the ekinex® Touch&See unit. The integrated temperature controller acts as a “slave”: the switch over is carried out by input communication object [DPT 1.100 heat/cool].
