The alarm page shows the alarm status of the heater, enables the user to

off remotely using a software or hardware remote interface to the heater
(depending on the heater options) and disables turning the heater on and
off from the touch screen. The mode of the heater can only be changed

All of the heater alarms are listed on this page. When the heater system
enters an alarm state the heater is turned off and a horn sounds. This
horn can be turned off by pressing the reset button or by pressing the
turning off audible alarm off button on the alarm page.
