Settings menu
The menu is adapted to your system automatically. Some menu items are
only available if the system has been set up accordingly. The menu items
are only displayed in systems in which the corresponding system
components are installed, e.g. automatic filling facility or Key Timer.
The factory settings are
highlighted
in the following table.

On natural gas appliances:
▶ Measure the gas rate.
▶ Compare the measurement with the setting tables (
▶ Correct deviations.

The delay prevents sudden changes in the water supply
pressure from causing the burner to briefly operate
although no water is drawn off.

…50 seconds
The delay concerns heating operation in systems in which
the DHW outlet of the solar-heated DHW cylinder is
connected to the cold water inlet of a combi boiler. DHW
heating by the combi boiler will be suppressed expecting
that solar thermal DHW will reach the hot water
temperature sensor prior eliminating the need to run the
boiler. This avoids unnecessary operation of the combi
boiler. Set the heating delay in accordance with system
conditions.

Heat demand
• Saving energy: intelligent heating pump stop in
heating systems with weather-compensated
controller. The heating pump is only switched on
when needed.
• In case of a heat requirement: the flow temperature
controller switches the heating pump. When there is a
heat energy demand, the heating pump starts up with
the burner.
