5 Tips on saving energy
Economy heating
The device is designed for low energy consumption and low environment
pollution but with a high degree of comfort. The fuel supply to the burner
is regulated according to the heat energy demand of the home. If the heat
energy demand is lower, the device continues to operate with a small
flame. Experts refer to this process as modulating control. The
modulating control keeps the temperature fluctuations low and
distributes heat uniformly inside the rooms. This may mean that
although the device is in operation for a longer period of time, it actually
consumes less fuel than a device that is constantly being switched on
and off.
Heating controls
To optimise the performance of the heating system, we recommend
using a room temperature-dependent controller or weather-
compensated control unit and thermostatic valves as heating controls.
Thermostats
Fully open the thermostatic valves to reach the required room
temperature. Increase the required room temperature at the control unit
if the temperature is not reached after a prolonged period.
Floor heating
Never set the flow temperature higher than the maximum flow
temperature recommended by the manufacturer. We recommend using
a weather-compensated control unit.
Ventilating
Close the thermostatic valves when ventilating, and fully open the
windows for a short time. Never leave windows slightly open during
ventilation. Otherwise heat will always be drawn out of the room without
noticeably improving the ambient air.
Hot water
Always set the DHW temperature as low as possible. Choosing a low
setting at the temperature controller means significant energy savings.
In addition, high DHW temperatures result in increased calcification and
thus impair the function of the device (e.g. longer heat-up times or lower
draw-off volume).
Circulating pump
Set the DHW circulation pump, if installed, using a time program which is
customised to suit your individual requirements (such as morning,
midday or evening).

Faults

6.1

Reset faults

The symbol H indicates that a fault has occurred. The cause of the fault
is displayed in encoded form (e.g. fault code 228).
Repeated attempts to reset a fault can lead to the appliance being locked
for safety reasons (fault code 2980). This lock can only be removed by a
qualified professional or the customer service after the cause of the fault
has been determined and remedied on site.
▶ Switch off the appliance and switch it on again.
-or-
▶ Reset the fault on the appliance.
As soon as the fault is no longer displayed, the appliance returns into
operation.
If the fault is still displayed:
▶ To ensure system safety, call a qualified professional or the customer
service immediately.
▶ Inform them of the fault code and the appliance data.
▶ Arrange an on-site appointment and have the cause of the fault
determined and remedied immediately.
