Evolution EV AC

ALARM CODES

The

Evolution EV AC

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:

AL AP

bar

ºC

Pressure.

This alarm may be set off due to the water having

been drained from the boiler or due to leakage in the

installation.

If this alarm occurs repeatedly, you should contact the

AL AT

bar

ºC

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.

AL AQ

bar

ºC

Burner.
