Dear Customer,
The controls are the “brain” of your heating
system. We have set it at the factory so that the
settings will be appropriate for most cases. This
way, daily operation is easy. The large, clear
display of the controls “speaks plain text” and
shows all relevant information.
Program space and water heating
With the controls you can set how warm you want
it at what times. We have already set various
scenarios from which you can choose.
An example: do you work and therefore are you
not at home during the day? Then perhaps you
only need full heating comfort in the mornings
and the evenings. During the day you save energy
in “economy mode” and at night, the heat is
reduced further still. Perhaps you have entirely
different needs because you are at home all day?
Whatever your lifestyle and your habits may be --
the heating system will adapt itself to your needs.
Even for unforeseen cases: 100% comfort
Did you get home earlier than planned and would
you like to have the house warm right away even
though your boiler is in “economy mode”? In this
case the controls switch to “heating mode” right
away with the press of a key. In just a short time,
you will be as comfortable as usual. Another
example: you would like to shower even though
your boiler is currently running in “economy
mode”? Here too, the press of a key can help you.
The water is heated and in just a short time you
can enjoy your hot shower. Depending on the
type of hot water heating, the system returns to
“economy mode” automatically after half an hour
or after an hour.
Consideration of the outdoor temperature
This is an outdoor reset control. It increases or
decreases the output of your heating system
depending on the outdoor temperature.
The controls can be installed on the boiler or
mounted directly on the wall in the living area. If
it is in the room, it can also be used to record the
room temperature for optimizing comfort.
Solar optimization
With our patented process
“SolarInside ControlUnit”, you save up to 15%
additional energy during hot water heating if you
have a solar thermal system installed. You can
find information about the solar yield on the
controls’ Info menu.
These operating instructions
These operating instructions contain the most
important information on daily operation of the
controls.
There is a listing of other interesting functions of
the controls in section 6.
If you would like to learn more, there is a detailed
description of all available functions in the
detailed installation and operating instructions.
Specialized terms are explained for you at the
end of these operating instructions.
We hope you will enjoy your new Bosch product.
Your Bosch team
