When there is a heat demand on CH and the cylinder
contains sufficient heat (heated by the sun) the
modulating 3-way valve will pass the CH-circuit via
the Solar-CH coil in the cylinder. Sensor T8 and T9
will measure the temperature differerence and
togehter with the standard data from the CMS it
decides if heat may retreived from the cylinder or
that the boiler has to be fired.
DHW demand is alway priority and if the cylinder
contains not sufficient heat because insufficient
solar influence, the boiler will be fired.
When an outside sensor is connected to the boiler,
the boiler works weather dependantly. This means
that the boiler control measures the outside
temperature and flow temperature. With this data
the boiler calculates the optimal flow temperature for
the installation.
The efficiency of the boiler is very high and the
radiation convection and standby losses very low.
The emission of noxious substances is far below the
fixed standards so the boiler meets the
requirements of SEDBUK Class A.
When the boiler is connected to an ATAG BrainQ
information interchange takes place between the
boiler and the BrainQ. For more information
regarding the ATAG BrianQ, please refer to the user
manual.

Example SEDBUK ClassA
Normally the pipes
between absorber and
cylinder are insulated.
However it needs your
attention that the pipes
during operation can
be extreemly hot
(>120°C).

Error, maintenance and warranty
If a fault is detected the boiler will be blocked. This
will be reflected, by an alternate display of
Good,
with an
E
of Error or a
BL
of Blocking and a number
code.
You can try to reset the boiler by pressing the
Reset key once. If the problem remains please
contact your installer and inform them about the
fault and give them the number code.
If you discover any leaks from the boiler contact
your installer.
We advise you to obtain a service contract with
your installer for regular maintance and
adjustment to keep your boiler safe and in good
condition.
The casing of the boiler consists of metal and
plastic parts which can be cleaned with a normal
non abrasive cleaning agent.
You can find the warranty conditions in the
warranty card which is supplied with the boiler.
Checking the solar pump
When there is sufficient sun light to heat the cylinder
the solar pump will switch on. When the display is
set to the Technical readout it will show
.
After sun set the solar pump may not run. In case the
pump still runs switch off (0) the solar system by
means of the main sun switch on the Control Tower
and contact your installer.
All maintenance activities should be carried
out by a qualified and certified installer only.
