10.12 WATER TEMPERATURE SENSOR FAULT
This alarm goes off when the sensor for detecting water temperature
is disconnected or it breaks. During the alarm state, the thermo-
stove will be in the turn-off stage (
see drawing D76
).
In case of this alarm appears you must be in touch with the technical
support service.
10.13 WATER TEMPERATURE ALARM
It goes off when the probe detects a water temperature higher than
90°C. Therefore the display shows the following message ( see
drawing D77 ):
In case of this alarm appears you must be in touch with the technical
assistance service.
10.14 CIRCUIT HYDRAULIC PRESSURE ALARM
It goes off when the pressure transducer detects an out of bounds
pressure, either lower than 0.4 bars or higher than 2.5 bars. The
system automatically interrupts the pellet supply and the display
will show on the screen an alarm. Right after, the turn-off stage is
activated ( see drawing D78 ).
In case this alarm appears you must be in touch with the technical
support service.
10.15 ALARM LIST, PROBLEM AND POSSIBLE SOLUTIONS
Alarm
Code
Description Problem Possible solution
AL1 BLACK OUT
The stove has been temporarily
without electric current.
Press button 4 for a few seconds and let the final cleaning stage
finish. The boiler will come back to the turn-off status.
AL 2 SMOKE PROBE Problem with the smoke probe. Check the probe connection or replace it.
AL 3 TEMP. SMOKE
The smoke temperature is higher
than 270ºC.
Regulate the pellet loading and/or the extractor speed. Verify
the type of fuel that has been used.
AL 4
BREAKDOWN
EXTRACTOR
Problem with the smoke extractor. Check the extractor electrical connection or replace it.
AL 5 START-UP FAILURE The fuel does not fall or burn.
Check the geared motor and the resistor way of working. Check
a possible blockage of the auger feeder. Verify that there is fuel
in the tank.
AL 6 NO PELLET
There is no fuel in the hopper or it
does not fall inside the burner.
Refill tank. Check the auger’s operation. Check the fuel
characteristics and that it has not become compacted. Clean
the bottom of the hopper.
AL 7 THERMAL ALARM
The fuel thermal security
thermostat has shot up.
Restart the thermostat manually. Check the reason why the
temperature is excessive and provoked the overheating (fuel
load, excess draught, fuel type...)
AL 8 DEPRESSION
The combustion chamber is on
depression.
Verify that the chamber is hermetic: check locks, gaskets… etc.
Check that the flue installation is correct (excess of horizontal
sections, elbow joint, etc). Possible fuel blockage.
AL 9 LACK OF FLOW
Lack of primary air or installation
not appropriate.
Check the primary air inlet. Verify installation (excess of
horizontal section, curves, dirtiness, etc).
AL DIRTY FLOWMETER The flowmeter sensor is dirty. Clean the flow sensor to get a proper reading. .
AL FLOWMETER FAILURE The flow sensor is broken. Replace the flow sensor.
AL WATER PROBE Problem with the water probe. Check the probe connection or replace it.
AL A HOT WATER The water temperature is high.
Check the pump is working. Check Parameter Pr 33. Check the
water system installation. Purge properly.
AL E WATER PRESSURE
Problems with the hydraulic circuit
pressure. Pressure over 2.5 bars
or under 0.4 bars.
Check the hydraulic pressure of installation. Working pressure
should be between 1 and 1.5 bars.
