7 Energy saving tips
Economy heating/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.). Otherwise 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 should
start is not set too low. Cool 109 the living space also
consumes energy.
Venting 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 turn the room thermostat down.
DHW heiltlng on demand
• Use the time program for DHW heating automatic mode.
8 FAQ
Why do I set a set room temperature, even though it is not
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 outdoor
temperature?
Even in summer mode radiators can heat up for a short period
in special circumstances, such as when the circulation pump
starts automatically at a certain interval to prevent it "jaming"
(blocking) . If the circulation pump should by chance start
Energy saving tips
immediately 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 run at night. even though the home is
not being heated at all or only very little?
If the outside temperature 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 room temperlture is
hicher
than the
required room temperature. Why Is the heat source
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 influence) , 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 remote control.
Why does the heating not switch off even though the
outside temperature hilS reached the temperature
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 period, 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.
