Description

The room set target temperature is the tempera-
ture to which the heating should be regulated in the
operating mode "Heat" or during the time slots.
22 °C
15 °C
Note: Select a room temperature that is just high
enough to ensure your personal well-being
(e.g. 20 °C). Each degree over and above the set
value means an increase in energy consumption of
around 6 % per annum.
The set-back temperature is the temperature to
which the heating is regulated during the set-back
period. An individual set-back temperature can be
set for each heating circuit.
The set operating mode determines under which
conditions the assigned heating circuit or hot water
circuit should be regulated.
The following operating modes are available for
heating circuits:
Auto: The operation of the heating circuits alter-
nates between the Heating and Energy Saving oper-
ating modes in accordance with a settable timer pro-
gramme.
Eco: The operation of the heating circuits alternates
between the Heating and Off operating modes in ac-
cordance with a settable timer programme. The
heating circuit is switched off during the set-back
period provided the frost protection function (de-
pending on the outside
temperature) is not activated.
Heating: The heating circuit operates at the room
set target temperature regardless of any settable
timer programme.
Energy sav: The heating circuit operates at the set-
back temperature regardless of any settable timer
programme.
Off: The heating circuit is off, provided that the frost
protection function (depending on the external tem-
perature) is not activated.
Note:
Additional heating circuits are displayed, depending
on the system configuration.
