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.
