The ATAG Q-Solar boiler is a room sealed,
condensing and modulating central heating boiler
with an integrated hot water facility. The boiler uses
free solar energy for central heating and domestic
hot water.
The boiler anticipates the heat demand of the central
heating system or the hot water facility. As well as
for the heating system as for the domestic hot water
fascility solar heat from the cylinder is used first. The
solar heat is received by the absorber and
transferred to the water in the cylinder. When there
is insufficient sun light the boiler will switch on to
meet the heat demand. The boiler will anticipate its
power to the installation and will switch on as less
as possible. On this way the control strives for a
maximum of comfort and efficiency.
The boiler is provided with an intelligent control
system (CMS Control Management System).
To anticipate on installation noises the boiler is
provided with a so called gradient control. This
control takes care that when the boiler fires it does
not burn on full power, but slowly increases the
power. This taks care of an even increase of the flow
water temperature.
The absorber pump is activated if the temperature in
the absorber is approx. 10°C higher than the
temperature in the cylinder. The absorber pump
switches off automatically as soon as this
temperature difference has dropped to approx. 2°C.
The pump also switches off automatically as soon
as the cylinder has reached a temperature of 80°C.
The controller allows the pump to restart once the
temperature of the cylinder has dropped to 75°C.
Room sealed boiler
The boiler retreives its
combustion air from outside
then discharges the flue
gasses to the outside.
Condensing
Retrieves heat from the
flue 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.

Adjustments
The boiler has a large number of settings options.
We advise you to contact your installer for
adjusting the boiler to the required settings.
Adjusting the flow water temperature (CH)
-
Press the Mode key briefly
(from the Technical reading).
The display will show PARA .
-
Press the Step key once.
The display will show 1 85 .
-
Press the + or the - key to alter the adjustments,
if necessary.
-
Press the Store key to confirm the setting.
The display will flash once.
-
Press the Mode key briefly.
The display will show StbY for a short while and
will return to the Technical reading.
The flow water temperature that has been adjusted
only applies to the central heating and is independent of the hot water facility for the
cylinder.
