Alarms
Alarm button (
pos.1

fig. 2
) opens the alarm queue. By pressing this button and active and non-
acknowledged alarms will be displayed in the menu window. The LED for alarms (
pos.2
in
fig. 2
) is
blinking if there are non-acknowledged alarms and shine steadily if the alarms are still active but have
been acknowledged. If there are multiple alarms use UP/DOWN buttons to move between them. An
alarm can be acknowledged or blocked by using OK and UP/DOWN buttons. To abort and go back to
the start menu select Cancel and press the LEFT button.
For alarm settings see the Commissioning protocol in the installation description (
page 35 and 36
).
Extra stop function
For some alarm types such as electric heating high temperature limit and water heating frost
protection it would be dangerous to not stop the unit on alarm. Therefore, for such alarm types, the
program will always reset the stop function to Active even if the operator should choose Inactive.
It is unfortunately not possible to remove the display text concerning the stop function for these alarm
types. This since the available program space demands that all alarms are treated in the same way in
the display.
