Description
The Set value day is the temperature at which the
2
heating is to regulate in the "Heating" mode or dur-
ing the time window.
The set-back temperature is the temperature to
which the heating is regulated during the set-back
22°C
period. An individual set-back temperature can be
15°C
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 an adjustable timer
programme.
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 (which
depends 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 Saving: 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.
