*) The prerequisite is that the heating characteristic has been correctly set on the outside-temperature controlled pro-
grammer so that a room temperature of approx. 20 °C is obtained with the room thermostat function switched off.
**)Provided a temperature reduction of –25 K has been set on the outside-temperature controlled programmer.

Important Notes

6.1 Saving Energy

• The reducing of the room temperature over
the day or night saves considerable energy.
With the reduction of the room temperature
by 1 K (°C), up to 5% less energy is used.
Note: It does not make sense to reduce the
room temperature under +15 °C, how-
ever, since intense reheating consumes
more energy than the uniform supplying
of warmth.
• For buildings with good heat insulation, the
reduced temperature setting may possibly
not be reached. Energy is saved in spite of
this, however, since the heating unit remains
switched off.
In this case, the switching time for reduced
operation can also be set for an earlier time.
• For ventilating, do not leave the windows in
the tilted position. In this manner, heat es-
capes continuously from the room without
the air in the room being significantly im-
proved. Therefore, avoid continuous ventilat-
ing!
It is better to ventilate briefly but intensively
(window completely open).
During ventilating, set the temperature regu-
lator to a lower value.

6.2 Information for Operation with
Room Temperature Sensing:
– The room (main room) in which the remote
control is installed determines the tempera-
ture for the other rooms.
This means that the room temperature in the
main room acts as a parameter for the com-
plete heating network.
– For this reason, thermostatically regulated
heating radiators that are mounted in the
main room must always be completely open.
Otherwise the thermostatic valve restricts
the heat supply although the regulator con-
tinuously demands more heat.
If a lower temperature is desired in adjacent
rooms or if the radiators should be shut off
completely, the radiator valves (thermostats)
are to be set accordingly.
In this case, it is recommended to forego the
room temperature sensing.
– Since the room in which the remote control is
mounted acts as the main room, heat from ex-
terior sources (e. g. sun radiation, fireplace,
etc.) can lead to inadequate heating in the
other rooms (Heating unit remains cold).
