ALARM CODES
The
Evolution Solar HDX
boiler has an electronic circuit which performs continuous self-testing to
detect any operating failures in the boiler. When the electronic control detects an operating error, it
indicates this by showing an alarm code on the display. The following list describes the possible alarm
codes:
CODE
ALARM
DESCRIPTION
Pressure
The pressure in the installation has dropped to below 0.5 bar. The boiler
will cut out. To unblock it, fill the installation at a pressure of 1 - 1.5 bar.
This alarm may be set off due to the water having been drained from the
boiler or leakage in the installation.
If this alarm occurs repeatedly, you should contact the nearest official
technical assistance service.
Temperature
The boiler has exceeded the safety temperature of 110 ºC. The boiler will
cut out. To unblock it, press the safety thermostat button when the
temperature has dropped.
If this alarm occurs repeatedly, you should contact the nearest official
technical assistance service.
Burner
The burner has cut out. To unblock it, press the illuminated button on

Overpressure
This indicates that the water pressure in the boiler is over 2.5 bar,
warning that the installation is in overpressure status. Boiler functioning
will NOT cut out.
To restore normal boiler functioning, drain the boiler until it reaches a
pressure of 1 – 1.5 bar.
If this warning occurs repeatedly, you should contact the nearest official
