Technical terms
Automatic operation mode
The heating system always follows the heating
program and automatically switches between the
operating modes
Frost.
Combi boiler
A boiler that can heat up drinking water and
heating water in one device simultaneously.
Constant operation
In constant operation, the automatic operation or
the heating program is interrupted and heating
up to the corresponding "desired" room
temperature takes place.
DHW program
The DHW program specifies at which switch
times there should be DHW heating and a
recirculation pump should run. If the DHW
program is connected to the heating program,
the heating program also determines when DHW
heating is active and the recirculation pump
operates.
DHW storage tank
A DHW storage tank stores large quantities of
heated drinking water (e.g. 80 gallons (300
liters)) and thus provides sufficient hot water at
the taps. This is ideal for long showers, for
example.
Factory settings
Values saved permanently in the controls (e.g.
complete heating programs) that are available
even if all customized settings were reset.
Frost protection
Frost protection is the lowest temperature that
the controls permit. Frost protection prevents
freezing of the building.

Groups of days
For the convenient setting of the heating program
or the DHW program, there are groups of days
available (e.g. Monday - Friday, Saturday and
Sunday, etc.) In association with the group of
days selected, a setting is made for several days
at the same time.
Heating program
A heating program automatically switches the
operating mode at fixed times. If the DHW
program is connected to the heating program,
the heating program also determines the switch
points for DHW heating and the operation of the
recirculation pump.
Heating zone (or heating circuit)
The heating water flows into a heating zone and
refers to a part of the heating system. In a heating
system, there can be several heating zones.
These controls can regulate two separate heating
zones. Depending on the installed heating
system, for example, one heating zone can warm
up the radiators and the other heating zone the
radiant floor heating.
Operating mode
The operating modes are Comfort / Economy /
Frost. They are depicted with the symbols
/
.
Each of these operating modes is assigned a
"desired" room temperature (temperature level)
that can be changed.
Operating mode selector
Use the operating mode selector to switch
between the heating program and constant
operation.
