Alarms
Alarm button (pos.1) opens the alarm
queue.
Press this button and active and non-
acknowledged alarms will be displayed
in the menu window. The LED for
alarms (pos.2 ) is blinking if there are
non-acknowledged alarms and steady
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 start
menu select Cancel and press LEFT
button. For alarm settings see the
Commissioning protocol.
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.
