what you can do to correct the problem that caused the alarm.
reset alarm In most cases it is enough to select "reset alarm" to correct the
problem that caused the alarm. If a green light illuminates after selecting
"reset alarm" the alarm has been remedied. If a red light is still visible and a
menu called ”alarm” is visible in the display, the problem that caused the
alarm remains. If the alarm disappears and then returns, contact your installer.
