Heating program
A heating program provides an automatic
changeover between operating modes at fixed
switching times. If the DHW program is
associated with the heating program, the heating
program also determines the switching times for
DHW heating and the operation of the DHW
circulation pump.
Holiday program
The holiday program enables an interruption of
the otherwise applicable controller settings over
several days. After the holiday program has
expired, the controller operates with the
previously applicable settings.
Operating mode
The operating modes are Comfort/Economy/
Frost. They are identified by the symbols / /
.
A "required" room temperature (temperature level)
that can be adjusted is assigned to each of these
operating modes.
Operating mode selector
The operating mode selector lets you change
between the heating program and constant
operation.
Switching time
A certain time at which the heating system starts
to heat, or DHW is produced, for example. The
switching time is part of the heating program or
the DHW program.
Temperature level
The "required" room temperature that is assigned
to an operating mode. The "required" room
temperature can be changed. See the
explanations on operating mode.
Thermal disinfection
This function heats up the DHW to a temperature
in excess of 60 °C, which is sufficient to kill
pathogens (e.g. legionella bacteria). Observe the
anti-scalding safety instructions.
Weather-compensated controller
A weather-compensated controller automatically
regulates the flow temperature subject to the
outside temperature and in conjunction with a
time program.
