status cannot be changed before issuing an unblock command.

ALARM screen
Fig. 57
On the bottom line the alarm type and name is scrolled and in the middle of the top line “ALARM” blinks, while “info” and the alarm code “Axx”
are steady on.
The alarm notifying sound may be stopped by pressing the key
On/Off
(key #5); if the key is pressed for more than 2s, the alarm will be cancelled
after a processing wait time (See Fig. 58). After a cancel command has been issued, if the alarm cause is removed, the display reverts back to the
START screen (See Fig. 48).
While the ALARM screen is displayed (See “Fig. 57 ALARM screen”), if the key #1 is pressed for 5s, the main menu is accessed; from within this
menu the setting up errors which might have caused the alarm condition may be corrected. The heater status may be monitored also from within the
info menu.
