Energy saving tips

Economy mode
• Use the time program by activating automatic mode. Set
the required room temperatures for the heating and
setback modes in accordance with your personal
temperature preferences. Adjust the time program to suit
your lifestyle.
– Heating mode = Normal heating
– Setback mode = Active living, away from home or
asleep.
• Set the thermostatic valves in all rooms so that the required
room temperatures can be achieved. Raise the
temperatures for the operating modes only if the required
room temperature is not achieved after a prolonged period.
• If the user interface 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 the
room adequately.
• If you reduce the room temperature by 1 K (1 °C), you can
save up to 6 % energy.
However, allowing rooms that are heated on a daily basis to
drop down to below + 15 °C is not recommended. That
would permit the walls to cool down too much. During the
heat-up phase, the ambient climate would be disturbed by
the cool walls that would still radiate cold. If you then raise
the room temperature further, more energy would be spent
than with a regular supply of heat.
• With good heat insulation of your building, it is possible that
after a heating phase the desired room temperature for the
setback mode will not be reached. Nevertheless,
energy is being saved as the heating system stays switched
off.
You save still more energy if you set the switching time for
the setback mode earlier.
Air properly
Open the windows completely for a short time instead of
allowing them to stand ajar. If windows are left ajar heat
dissappears continuously from the room without the air in the
room become much better.
Close the thermostat valves while airing the room.

DHW heating on demand
• If the heating phases and the times at which hot water is
required are closely aligned, use the time program for DHW
heating in automatic mode as well.
• Set the DHW temperature to as low as possible. This saves
a lot of energy without noticeably impairing DHW
convenience.
