Description
The room set target temperature is the tempera-
2
ture to which the heating should be regulated in the
operating mode "Heat" or during the time slots.
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
22°C
set for each heating circuit.
15°C
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 hea-
ting circuits:
Auto: The operation of the heating circuits alter-
nates between the Heating and Energy Saving ope-
rating modes in accordance with a settable 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 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.
