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 OMFORT and LATHERM HZR E.

1. Select a suitable mounting location in the room, in
which the temperature should be adjusted (e.g. liv-
ing room). Take care, that no external heat can in-
fluence the remote control!
2. Remove the housing cover of the remote control!
Here it is important to press the housing cover
slightly together at the top and at the bottom side!
3. Mark the two mounting holes (see drawing) and
drill (Ø 5 mm), fit in the enclosed dowels!

anger to life due to electric shock!
 Switch off the power supply of the heating controller every time before the clamp cover is opened!
 Make sure, that the controller cannot be switched on!
NAGER
onnect the remote control to the heating controller. Use a 2-wire weak-current line and connect it via screw
terminals (single / fine wire, max. 1,5 mm
2
) according to the wiring diagram of the heating controller.
Patch the eBus connection (+ and -) of the heating controller directly with the bipolar connecting terminal of
the remote control. The polarity need not to be observed! A suitable strain relief has to be provided!
The low voltage conducting lead has to be laid separately to power supply voltage conducting leads. Now
mount the clamp cover again on the heating controller and clip on the housing cover of the remote control.
The digital remote control is automatically detected by the heating controller during the first commis-
sioning of the remote control. This procedure may last a few seconds!
anger to life due to electric shock!
The remote control may never be mounted on a flush socket, in which there is already power supply
voltage! Make sure that there is only a weak-current line in the flush socket!

10. Your digital remote control is structured like this
Your remote control has a clearly arranged display, which indicates information (e.g. about actual tempera-
tures) and which helps you to adjust values. The starting display appears, when the remote control is properly
activated and in operation. This is the basic structure of the starting display. If your heating specialist has
chosen other adjustments at the heating controller or at the heating system, different symbols may partly
appear:

11. Functions and adjustments
11.1. Basic information about the menu navigation
With only four keys you can adjust your heating controller or your heating system. With the keys you can get
from the starting menu (an example is shown on the previous page) into every submenu to see the desired
values of the heating system or to change them. Please consider, that values can only be changed at the
remote control, if these values or dates are enabled for changing by the manufacturer. The display lightening
is switched on automatically, if a key is pressed for the first time. The lightening is switched off 30 seconds
after the last key has been pressed.
Attention!
 The adjustments at the digital remote control have always priority to the adjustments at the heating
controller!
 Please also consider the operating and the commissioning manual of the heating controller for all
works and adjustments at your digital remote control.
!
Basically:
 the key acknowledges your choice
(change of an operating mode, move to a sub-
menu, save a changed value)
 the key deletes your choice (manual
switchover, leave a submenu, delete an entered
value)
 the keys and choose a submenu

20. Errors and troubleshooting
!
Please consider basically:
 It is not possible to adjust the digital remote control during data transfers. A flashing impulse
symbol ( ) on the display of the remote control indicates a data transfer.
 Time and date can not be adjusted at the remote control. This can only be done at the heating
controller.
Please check the following points, if your remote control does not operate successfully:
1. The communication to the heating controller is disturbed or there is an error at the heating controller, if the
display permanently shows FEHL.
2. The electrical connection is correct, if the display shows a meaningful information. In case there is no
information on the display, check if the device is connected correctly.
3. heck if there is an error, that is described in the commissioning manual of the heating controller.
Replace the digital remote control or the heating controller, if the error still exists after checking the above
mentioned points.
