9.5.4.2 Alarm log Heat pumps
Here you can read information about the latest alarms
from the heat pump that sounded the alarm. The latest
alarm is displayed at the top and the four latest alarms
are shown under
Stored alarms.
An alarm which reoccurs within an hour is ignored so
as not to fill up the log. If all the alarms are the same,
this can indicate that there is an intermittent fault, e.g.
aloose contact.
9.5.4.3 Factory settings Coded
This menu is intended to set the manufacturer’s
operational and alarm limits. A 4-digit code must be
specified to be able to amend these limits. However,
you can also take a look without any code to see what
options feature in the menu.
!
NB: Only an authorised service engineer is allowed to log in to the Factory settings
coded option. Severe operational problems and faults may occur affecting the
product if values are amended without authorisation. Note that in such cases the
warranty terms do not apply.
