1. Product description
The digital remote control DFW HZR with integrated room sensor allows to adjust the heating controller from
afar. That means, all important adjustments of the heating system, like changing the day and night setpoint
room value or choosing the operating mode, can be done directly and comfortable from the living room at the
remote control. In addition the remote control registers the room temperature and the heating controller
analyses the temperature (room influence). To assure this function a constant bi-directional data-exchange is
carried out between remote control and heating controller.
The digital remote control DFW HZR can be installed in connection with the heating controllers LATHERM
HZR COMFORT and LATHERM HZR E.
