Caution!
Malfunctions caused by incorrect
installation!
Any external sensor connected to the boiler
will be ignored.
Connect the external sensor to the control-
ler.
Abb. 5.11 Connecting the DCF receiver
left: with the external sensor (VRC DCF) supplied,
right: special solution with the VRC 693 external sen-
sor
If no radio signal can be received at the location where
the external sensor is installed, a solution using the
VRC 693 external sensor is required.
Connect the external sensor to the controller.
Wire the DCF receiver as shown in Fig. 5.11.
If you have fitted the VRC DCF external sensor, note
that:
Normally, the synchronisation time for radio recep-
tion is approx. 5 minutes but, depending on the
local and structural conditions as well as the wea-
ther, can take up to 20 minutes.
