The device (1) has an inlet (11) connected to a control wire (3) for receiving control commands, where the control wire is utilized for sending a number of control commands e.g. comfort commands, to a heater (2). A converter is connected to the inlet, and transforms the number of control commands into a number of instructions intended for the heater. An output is connected to the converter and adapted to be connected to the heater for sending a command for controlling the heater based on the control commands. |
