There are 3 alarm levels. The display can show 3 different
alarms at the same time. The alarm must be acknowledged
and reset by pressing the rotary/push button.
Level 1 - The information alarm:
does not affect the HP operating, but informs the user that
there is a problem, which might need action and should be
resolved as soon as possible. (
Alarm no. 8, 9, 10 and 11
).
Level 2 - The cooling circuit alarm:
This alarm level stops the DHW production via HP. If a supple-
mentary heating is chosen in the “
H.pump
” parameter menu
(“
HP+EL
” or “
EL
”), DHW is generated by the supplementary
heating up to the DHW setpoint
temperature. (
Alarm no. 3, 4, 5 and 6
).
Level 3 - DHW HP alarm:
The DHW production will cease completely. A severe
malfunction or defect is supposed. This alarm level needs the
intervention of your installer or the manufacturer’s after-sales-
service. (
Alarm no. 1 and 2
)
The user can see the alarms in the alarm menu, where also
the alarms are acknowledged. The problem/defect has to be
settled and the alarm has to be acknowledged, before
normal operation resumes. If there are simultaneous alarms,
the alarms are displayed (up to 3 alarms) in a sequence,
according to their priority.
Special handling of pressostat switch alarms (
alarm 5 & 6
)
The pressostat switch protects the compressor and the
cooling circuit against overpressure. At the first time the
problem comes up,
alarm no.5
is displayed and the HP stops
operating. LED (17) is flashing in red until the problem is
solved (pressure is normal again), it resumes in normal
operating mode automatically.
(LED indicator: standby mode = orange light; HP operating
mode = green light). If
alarm no. 5
persists, call your installer.
Should a pressostat problem occur again in less than 6 hours
after the first alarm, alarm
no.6
is displayed and the HP stops
operating. Call your installer! LED (17) is flashing in red until
the problem is solved (pressure is normal again) and the alarm
acknowledged by pressing the rotary/push button, The LED
(17) now flashes in orange. When the alarm is reset, the HP
will restart and LED (17) turns for constant light (standby mode
= orange light; HP operating mode = green light).
