Description of the boiler
Room sealed boiler
The boiler retreives its com-
bustion air from outside
then discharges the ue
gasses to the outside.
Condensing
Retrieves heat from
the ue gasses. Water
condensates on the heat
exchanger.
Modulating
Higher or lower burning
according to the heat
demand.
Stainless steel
Super solid kind of steel
which keeps its quality for
life. It will not rust or erode
in contrast to composition
materials, like aluminium.

The boiler will not function directly. The automatic de-aeration programm of about
17 minutes will start after one of the three programm keys is pressed. The display
will show where A stand s for Automatic de-aeration programm Active

It can take a while before all air has dis-appeared from a lled installation. Es-
pecially in the rst week noises can be heard which indicate the presence of air.
The automatic air vent in the boiler will make this air disappear, which means the
water pressure will reduce during this period and therefore topping up with water
will be necessary to adjust the ow water temperature
Turning the boiler off
Holiday
The ATAG BrainQ room
thermostaat is provided
with a holiday programm.
The holiday period can be
adjusted on the thermostat
itself. The central heating
and DHW supply are swit-
ched off during that period.
There is also the option
that only the central hea-
ting is switched off. With
all of these possibilities the
frost protection system is
active.

When a type of installation has been chosen with a low water-ow temperature it
is possible that in case of a severe winter period the temperature of the heating
system will need to be increased slightly. In such situations the installation choice
may need to be changed, so that a higher ow temperature can be chosen. This
adjustment would normally be carried out by your installer during the installation
and commissioning.
