4 Safety systems BS-04-00-00-00-01-BAEN
To prevent the boiler overheating, the controller reduces the
heat output in certain situations. If the boiler still threatens to
overheat, the controller responds according to a set of defined
safety levels.
Safety level 1 SY-04-00-00-01-01-BAEN
Boiler temperature 87°C
The flue draught fan stops and the combustion air supply is
shut off.
Safety level 2 SY-04-00-00-02-01-BAEN
Boiler temperature 95°C
The boiler is cooled by letting cold water into the temperature-
relief heat exchanger via the temperature-relief valve.
Safety level 3 SY-04-00-00-03-01-BAEN
Boiler temperature 100°C
All heating pumps and the cylinder charging pump are
switched on to carry heat away from the boiler.
Safety level 4 SY-04-00-00-04-01-BAEN
Boiler temperature above 100°C
The STL (safety temperature limiter) trips and switches all
boiler control functions off while the heating circulation pumps
continue to run. The system remains switched off even if the
boiler temperature drops back below 90 °C. The system must
not be started up again until any faults have been rectified and
the boiler has been checked.
Power failure SY-04-00-00-05-01-BAEN
The controller, the flue draught fan and all circulation pumps
switch off due to lack of electricity if there is a power cut. The
glowing fuel bed on the grate continues burn with the natural
draught of the flue. As this operating mode is not ideal, a
larger amount of ash collects on the grate as well. In addition,
the combustion air supply should be manually shut off on the
ash box door. To do so, open the ash box door from the right,
press the black release button on the relevant servo motor
and turn the air flap control anticlockwise as far as the stop.
As soon as the electricity supply is restored, the controller
takes control of the heating system again.
SY-04-00-00-06-01-BAEN
Opening fuel box door SY-04-00-00-07-01-BAEN
•The flue draught fan switches to maximum speed
•The supply of combustion air is shut off
•After the fuel box cover is closed, resumption of operation
is initiated
Danger: Risk of detonation.
Do not open any boiler doors during these
operating modes.
