7 Energy saving tips
Economy heat i ng/cooling
Use optimised operation . Set the required room
temperature in accordance with your personal
temperature preferences . The heat pump saves the most
energy when it is constantly in optimised operation .
Fully open the thermostatic valves in all the rooms . Only
increase the temperature setting at the user interface if the
room hasn't reached the temperature you require after
some time . If it gets too hot in a particular room , only close
the thermostatic valve in that room.
If a remote control is installed in your living space, it can '
capture the room temperature to optimise control
accuracy if set up accordingly . Keep the user interface
away from external heat sources (e . g. solar exposure , tiled
stoves. etc .). Otherw i se undesirable fluctuations of the
room temperature may result.
Never position large objects such as a sofa immediately in
front of radiators (maintain a clearance of at least 50 cm) .
Otherwise , the heated air cannot circulate and heat or cool
the room adequately .
Make sure that the temperature at which cooling sho u ld
start is not set too low . Coo l 109 the living space also
consumes energy .
Vent i ng property
Briefly open the windows fully instead of only a little . When
windows are open a little , heat is constantly drawn out of the
room without really improving the ambient air .
When venting the room, close the thermostatic valves on the
radiators or tu rn the room ther m ostat down .

8 FAQ
Why do I set a set room temperatur e, even though it is no t
recorded ?
By setting the room temperature , you change the heating
curve . Changing the heating curve , changes the temperature of
the heating water , and therefore also the temperature of the
radiators or underfloor heating system .
Why do the radiators get too hot with a high outdoo r
temperature ?
Even in summer mode radiators can heat up for a short period
in special circumstances, such as when the ci rculation pump
starts automatically at a certain i nterval to prevent it "j aming "
(block i ng) . If the circulation pump should by chance start
Energy saving tips
im m ediately after the heating up of hot water the residual heat
that is not used is moved away via the heating circuit and the
radiators .
Why does the pump r un at night . even though the home is
not be i ng heated at all or only very little?
If the outside temperat u re falls below a certain set point , the
heating system operates to prevent the system from freezing
up (frost protection) .
Why does the additional heat source run when the time
program switches from setback to heating?
After an extended period in setback mode , the additional heat
source and the heat pump may be activated in order to reach
the required heating water temperature . Shorter setback
phases or not using setback mode at all increases comfort and
prevents this heat-up behaviour from occurring .
The meawed r oom temperlture is hicher than the
required room temperature . Why Is the heat sourc e
nevertheless running ?
The heat source may be heating hot water.
Your system can be set to 2 different types of control
(7 Chapter 2. 2, page 4) .
With weather - compensated control (including with room
temperature inf lu ence) , the heat source can still operate even
if the measured room temperature is higher than the set room
temperature . Adjoining rooms are hence always sufficiently
heated without their own re m ote control.
Why doe s the heating not switch off even though the
outside temperature hilS reached the temperatur e
threshold set for summer shutdown?
Summer shutdown based on the outside temperature takes the
thermal inertia of the heated building mass into account
(damping due to building type). Therefore , when the
temperature is reached during the transitional pe r iod , it takes a
few hours before switchover actually occurs .
9 Eliminate fault
9.1 Eliminating " sensed " faults
A · sensed " fault can have various causes , which can usually be
eliminated by taking simple steps .
If it is too cold or hot for you , for example , the following table
will help you eliminate " sensed " faults .
