The Set value day is the temperature at which the
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
period. Each heating circuit can be set to its own
set-back temperature.
The selected operating mode determines under what
conditions the assigned heating circuit or hot water
circuit is to be controlled.
The following operating modes are available for
heating circuits:
Auto: the operation of the heating circuit alternates
between the "Heating" and "Energy saving" modes
in accordance with a presettable timer programme.
Eco: the operation of the heating circuit alternates
between the "Heating" and "Off" modes in accord-
ance with a presettable 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 is operated at the target
room temperature independently of any presettable
timer programme.
Energy Saving: the heating circuit is operated at
the set-back temperature independently of any pre-
settable timer programme.
Off: the heating circuit is off when the frost protec-
tion function (dependent on the external tempera-
ture) is not activated.
Note:
Additional heating circuits are displayed, depending
on the system configuration.
