FAULTS
Display Description Remedy
Black display and status bar for connection
set up is illuminated permanently
Communication cannot be set up between the heat
pump control unit and the RBE.
This can be caused by the software (settings in the
heat pump controller) or by the hardware (wiring)
Check whether:
• the RBE has been activated under the
System Settings in the heat pump
controller
• the RBE has been wired correctly with the
heat pump control unit
• the heat pump controller software is at least
Version x.68
The operating modes displayed in the RBE
do not correspond with those in the heat
pump
The RBE mirrors the operating modes from the heat
pump control. If a mode is not displayed in the RBE it
is also not displayed in the heat pump controller.
Activate the required operating modes
under the System Settings in the heat pump
controller. As these are basic settings for
operation of the heat pump system you must
get a competent person (installer) to make
the necessary changes.
If a non-self-resetting (hard) fault exists in the heat pump controller, this is displayed in the home by the room control unit, including the error code.
If the heat pump controller is congured in such a way that the second heat generator (ZWE) is activated automatically during a fault, this is also
displayed.
For further information on the displayed error code, please refer to the operating manual of the heat pump controller.
