(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.
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 pushbutton panel.
The board detects an anomaly on the system flowmeter.
Booster pump, if any, always working.
This occurs if there is overheating in the indoor unit due to
insufficient water circulating in the primary circuit; the
causes can be:
- low system circulation; check that no shut-off devices are
closed on the central heating circuit and that the system is
free of air (deaerated);
- pump blocked; free the pump;
- damaged flowmeter.
If the board detects an anomaly on the mixed zone 2 probe,
the system cannot work in the affected area.
If the board detects an anomaly on the mixed zone 3 probe,
the system cannot work in the affected area.
Indoor unit status / Solution
The system does not start (1).
Attention: the fault may be reset up to
5 times consecutively, after which the
function in inhibited for at least one
hour. One attempt is gained every
hour for a maximum of 5 attempts. By
switching the appliance on and off
again, the 5 attempts are re-acquired.
The indoor unit cannot produce
domestic hot water (1).
If normal conditions are restored, the
heat generator restarts without having
to be reset (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).
