ALARM DESCRIPTION
17.1
No fuel
In case the boiler temperature dropped in
OPERATION mode by the value of
DelT lack
of fuel
below the
boiler preset temperature,
the regulator starts counting
No fuel
detection time.
MENU Service Settings Boiler Settings
No fuel detection time
If, upon elapsing this time, the boiler
temperature has not increased by 1 C, the
regulator switches off heat recipients and
starts counting
No fuel detection time
again.
If temperature has not increased after this
time by 1 C, the regulator enters STOP
mode and generates alarm "No fuel”. To
reset the alarm - switch OFF and ON the
regulator.
In case the regulator erroneously
detected lack of fuel - increase the
value of parameter of
No fuel
detection time
- see sec. 1 or
decrease the value of
DelT lack of
fuel.
17.2
Max.boiler temp. excess
Protection
against
boiler
overheating
comprises two stages. In first instance i.e.
once the
Boiler cooling temp.
has been
exceeded, the
regulator attempts to reduce
the boiler temperature by activation of the
boiler pump, HUW pump and opening the
mixer servo (only in case mixer circuit = CH
ON). Has the temperature dropped - the
regulator returns to normal operation. Is the
temperature still increasing (and has reached
95 C), power supply to the fuel feeder and
the fan is off and permanent boiler
overheating alarm with sound signal is
produced. If, during boiler overheating time,
temperature measured by HUW sensor is
higher than
Max. HUW temperature
, HUW
pump goes off. In this manner, users of hot
utility water are protected from burning.
Alarm is reset by regulator switching off and
on.
Note: arrangement of temperature
sensor outside the boiler water
jacket (e.g. at the outlet pipe) is
not recommended because boiler
overheating may be detected with
delay.
If the regulator is SUMMER mode, the
regulator attempts in first instance to
discharge excess heat to HUW container.
HUW pump goes OFF if the temperature
measured by HUW sensor is in excess of
max
HUW
temperature
.
17.3
Exceeding max. feeder temperature
This alarm will occur after the feeder
temperature exceeds the service parameter:
Service settings> Boiler settings> Max.
feeder temperature
If the feeder temperature exceeds this value,
the regulator will enable the feeder for a
constant, programmed time and will activate
the poker. The airflow is disabled and the
pumps are enabled. After „pushing the fuel
out”, the regulator disables the feeder and
does not activate it again, even if the feeder
temperature is still high.
This alarm can be cancelled only after the
feeder temperature decreases, by pressing
the encoder knob or by restarting the
regulator.
The function of protection against
flame recession is inoperative if the
feeder sensor is disconnected or
damaged.
The function of protection against
flame recession is inoperative if the
regulator is not powered.
The
ecoMAX800P1-L
regulator
cannot be used as the only
protection against flame recession
in a boiler. Use additional protective
automatics.
