ALARM CODES
The
Evolution EV AC
boiler has an electronic circuit that performs continuous self-testing to detect
any operating failures in the boiler. When the electronic control detects malfunctioning, this is
indicated by an alarm code flashing on the display. The following list describes the alarm codes that
may appear:
