FAULT AND ANOMALY SIGNALS

The indoor unit indicates a possible anomaly through a code flanked by the symbol of a key "
sage "indoor unit anomaly" at the bottom of the display itself (Fig. 28).

(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised After-Sales Technical Assistance Centre).
Cause
The board detects an anomaly on the flow NTC probe.
Number of allowed resets already performed.
The board detects an anomaly on the storage tank probe
If the board detects an anomaly or incongruity on the elec-
tric wiring, the appliance will not start
The board detects an anomaly on the return NTC probe
The board detects an anomaly on the pushbutton panel.
The board detects an anomaly on the flowmeter.
Booster pump, if any, always working.
This happens when the hydronic module overheats due to
poor water circulation in the primary circuit. The causes
can be:
- pdc pump blocked; free the pump;
- damaged flowmeter.
If the board detects an anomaly on the zone 2 low tempera-
ture probe, the system cannot work in the affected area.

Appliance status / Solution
The system does not start (1).
The anomaly can be reset 5 consecu-
tive times, after which the function is
inhibited for at least one hour and it is
possible to try once every hour, for a
maximum of 5 attempts. By switching
the appliance on and off again, the 5
attempts are re-acquired
The hydronic module is unable to
produce domestic hot water (1).
If normal conditions are restored, the
heat appliance restarts without having
to be reset (1).
The system does not start (1).
If normal conditions are restored, the
system restarts without having to be
reset (1).
The system does not start (1).
Make sure the booster pump (option-
al) only activates when requested.
Check system circulation and
flowmeter.
Press the Reset button (1).
