5.2 Setting parameters in the basic display
The basic display is the controller's standard display.
After an extended period without any operations, the
display automatically reverts to the basic display.

The parameters highlighted on a grey background (ope-
rating mode, room target and cylinder temperatures)
can be individually set in the basic display.
The basic data consisting of day of the week, date, time
of day and outside temperature are always shown in the
upper area of the display.
When thermostatic control is activated, the measured
room temperature is shown in the second line of the dis-
play.
i
If a room temperature sensor is fitted, the
thermostatic control will be activated by the
heating engineer when commissioning the
heating installation.
You can set the day, date and time in Menu 1
( ¬ Chap. 5.3 ).
The outside temperature (-3 °C in the example) is
measured by the external sensor and transmitted to the
controller. The current room temperature is measured
by the room temperature sensor and transmitted to the
controller. The settable parameters are displayed below
the basic data:
for each heating circuit
the operating mode set,
target room temperature (for the displayed hea-
ting circuit)
for the cylinder
the operating mode set,
target cylinder temperature (hot water tempera-
ture)
i
The number of heating circuits your control-
ler displays in the basic display depends on
the configuration of your heating installation.

5.2.1 Setting the operating mode
By setting the operating mode, you inform the control-
ler about the conditions under which the assigned hea-
ting circuit or hot water circuit is to be controlled.
i
If Holiday is displayed instead of the opera-
ting mode, the holiday programme is active.
When the holiday programme is active, the
operating mode cannot be set.
It will be necessary to end the holiday pro-
gramme to do this.
The following operating modes are possible for:
CH circuit
Operating
mode
Effect
Auto The heating circuit is operated alternately in Hea-
ting and Energy Saving mode according to a pre-set
timer programme.
Eco The heating circuit is operated alternately in Hea-
ting and Off mode according to a pre-set timer pro-
gramme.
The
heating circuit is switched off during the set-back
period if the frost protection function (depending
on the outside temperature) is not activated.
The frost protection is effective outside the set
time window (
¬ Chap. 5.2 ).
Heating The heating is regulated at the daytime set room
temperature.
Energy
save The heating circuit is regulated at the nighttime
set room temperature.
Off The heating circuit is off if the frost protection
function (depending on the external temperature) is
not activated.
Symbol Meaning
If the symbol is displayed after the Eco or Auto
mode, a time slot is active. The heating installation
is producing heat.
If the symbol is displayed after the
mode, no time window is active.
The heating installation is in set-back mode.
Table 5.1 Operating modes for heating circuits
Circulation circuit and hot water circuit
Operating
mode
Effect
Auto The commands for charging the DHW cylinder or
for enabling the circulation pump are given accor-
ding to a preset timer programme.
On The charging of the DHW cylinder is constantly
enabled. If required, the cylinder is recharged
immediately and the circulation pump is constantly
in operation.
Off The cylinder is not charged and the circulation
pump is not in operation.
If the temperature in the DHW cylinder falls below
12 °C, the cylinder is reheated to 17 °C (frost pro-
tection).
