15 Alarms descriptions
15.1 Boiler max. temp. exceeding
Protection against boiler overheating is done
in 2 steps. In the first step , after exceeding
Boiler cooling temp., the controller tries to
reduce boiler temperature by dropping
excess of heat to the HUW container and by
opening mixer servomotors (only when Mixer
support = CH ON). If temperature measured
by HW sensor exceeds value Max. HUW
temp. then HUW pump is deactivated, what
is done to protect users against scalding. If
boiler temperature decreases, then the
controller returns to normal operation. If the
temperature will still increase (reaches 95ºC)
then constant alarm will be activated of
boiler overheating joined with sound signal.
The alarm can be deleted by pressing
„TOUCH and PLAY” button or activating and
deactivating power to the controller.
Locating temperature sensor
outside water coat of burner i.e. on
exhaust pipe is not beneficial,
because it may cause delay in
detecting boiler overheating state!
15.2 Burner max. temp. exceeding
Alarm appears after exceeding feeder
temperature above service parameter Max.
burner temp. If the burner temperature
increases above this value the controller will
begin burning off procedure. The alarm can
be deleted by pressing „TOUCH and PLAY”
button or activating and deactivating power
to the controller.
15.3 Boiler temp. sensor damage
Alarm appears by boiler sensor damage and
by exceeding measuring scope of this sensor.
When alarm appears the boiler is activated.
The sensor is to be checked and replaced if
necessary. The alarm can be deleted by
pressing „TOUCH and PLAY” button or
activating and deactivating power to the
controller.
Checking the temperature sensor is
described in point 12.11
15.4 Feeder temp. sensor damage
Alarm appears when feeder sensor is
damaged or by exceeding measuring scope
of this sensor. After alarm the boiler is burnt
off. It is necessary to check the sensor and
replace it if necessary. The alarm can be
deleted by pressing „TOUCH and PLAY”
button or activating and deactivating power
to the controller.
Checking the temperature sensor is
described in point 12.11
15.5 Feeder control system failure
The controller has an additional protection
preventing it from feeding fuel constantly.
This informs the user about failures in the
electrical system controlling the fuel feeder.
In case of alarm, stop the boiler and repair
the controller as soon as possible. It is also
possible to continue operation in emergency
mode. Before continuing operation, make
sure that the combustion chamber does not
contain excessive unburnt fuel.
Operating in emergency mode is
allowed only under user supervision
and until the arrival of the service
team to remove the failure. If user
supervision
is not possible,
extinguish the boiler. When
operating in emergency mode,
prevent
the consequences of
improper feeder work (feeder
working constantly or not at all).
15.6 Overheating boiler, STB open
contact
This alarm occurs after activation of
independent safety thermostat that secures
the boiler against overheating. The burner
will then be deactivated. After the boiler
temperature will drop down it is required to
unscrew an oval STB lid and then press the
Reset button.
15.7 No communication
The control panel is being linked with the
rest of the electronics with RS485 digital
communication link. In case a cable of this
link will be damaged, an alarm will occur on
the screen with the information “Attention!
