Fault affecting the heat source
Heat source faults are always displayed on the
heat source.
If there is a BUS connection between the user
interface and the heat source, faults are also
displayed on the user interface.
If in doubt, ask your contractor about the type
of connection.
Locking faults on the heat source can be rectified by
performing a reset.
▶ Reset the heat source.
See the operating instructions for the heat source for additional
information about eliminating faults affecting the heat source.
▶ If the fault cannot be rectified by a reset, contact your
contractor.

For a constant heating circuit only the Auto and Off are
available ( Chapter 5.3.2, page 21).
Operating modes for DHW heating are:DHW, DHW reduced
and Off.
An adjustable temperature is assigned to each operating mode
(except for Off).
Instantaneous water heater
With this type of DHW heating, DHW is available on demand.
Compared with DHW heating via a DHW cylinder, it can take
longer for the required temperature to be reached at the draw-
off points. This delay can be reduced by activating the keep hot
function ( Temperature maintenance).
Frost protection
Depending on the selected frost protection, the heat pump will
turn on when the outside and/or room temperature reaches
below a certain set threshold. Frost protection prevents the
heating system from freezing up.
Required room temperature (also desired or set
temperature/set room temp.)
The room temperature to be achieved by the heating system. It
can be set individually.
Default setting
Values permanently saved in the programming unit
(e.g. complete time programs) that are available at any time
and that can be reinstated according to demand.
