Anomaly signalled Cause Hydronic module status / Solution
E 10
Insucient system
pressure
Water pressure inside the central heating circuit that is suf-
cient to guarantee the correct operation of the heat gener-
ator is not detected.
Check on the heat generator pressure
gauge that the system pressure is
between 1-1.2 bar and restore the
correct pressure if necessary.
E 12
Storage tank probe
anomaly
e board detects an anomaly on the storage tank probe.
 e h yd r o n i c m o d u l e i s u n a b l e t o
produce domestic hot water (1).
E 15 Conguration error
If the board detects an anomaly or incongruity on the elec-
tric wiring, the appliance will not start.
If normal conditions are restored, the
heat generator restarts without having
to be reset (1).
E 16 Fan anomaly is occurs if the fan has a mechanical or electrical fault. Press the Reset button (1) (4).
E 20 Parasite ame block
is occurs in the event of a leak on the detection circuit or
anomaly in the ame control unit.
Press the Reset button (1) (4).
E 23
Heat generator return
probe anomaly
e board detects an anomaly on the heat generator return
NTC probe.
e system does not start (1) (4).
E 24
Push button control
panel anomaly
e board detects an anomaly on the pushbutton panel.
If normal conditions are restored, the
system restarts without having to be
reset (1).
E 26
System owmeter
anomaly
e board detects an anomaly on the system owmeter.
Booster pump, if any, always working.
e system does not start (1) (3).
M a k e s u r e t h e b o o s t e r p u m p (o p t i o n -
al) only activates when requested.
E 27
Circulation
insucient
is happens when the hydronic module overheats due to
poor water circulation in the primary circuit. e causes
can be:
- low system circulation; check that no shut-o devices are
closed on the central heating circuit and that the system is
free of air (deaerated);
- pump blocked; free the pump;
- damaged owmeter.
Check system circulation and
owmeter.
Press the Reset button (1) (3).
E 32
Mixed zone 2 probe
anomaly
If the board detects an anomaly on the mixed zone 2 probe,
the system cannot work in the aected area.
(1).
E 33
Mixed zone 3 probe
anomaly
If the board detects an anomaly on the mixed zone 3 probe,
the system cannot work in the aected area.
(1).
E 34
Safety thermostat
intervention Mixed
zone 2
During normal operation, if an anomaly causes excessive
overheating of the ow temperature in the mixed zone 2,
the unit indicates the malfunction.
e unit does not meet the zone
central heating requirement (1).
(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Aer-Sales Technical Assistance Centre)
(2) e anomaly can only be veried in the list of errors in the “Information” menu.
(3) e heat pump mode does not start, the heat generator stays active to satisfy the room heating and domestic hot water produc-
tion requests.
(4) e heat generator does not start, the heat pump mode stays active to satisfy the ongoing requests.
