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.

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 (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.
