Anomaly signalled Cause Hydronic module status / Solution
E 130
Zone 2 humidity probe
anomaly
Anomaly on the zone 2 humidity probe (optional). Zone humidity
cannot be checked.
In addition to the humidity, the dew point
is not calculated for the zone (1) either
E 177
DHW maximum time
block
Domestic hot water production is not met within the pre-estab-
lished time (5 hours)
e system continues to operate with
non-optimal performance (1)
E 178
Anti-Legionella cycle
block not successful
e anti-Legionella cycle is run without success within the pre-es-
tablished time (3 hours)
Press the Reset button (1)
E 179
Liquid phase probe
anomaly
e board detects an anomaly on the liquid phase NTC probe. e system does not start (1) (3)
E 181
Loss of remote control
communication
(zone 2)
This happens when an incompatible remote control is connected
or when communication between the hydronic module and the
remote control of the second zone is lost.
Cut power to the hydronic module then
power it back on. If the Remote Control is
still not detected at restart, the system will
switch to local operating mode, i.e. using
the controls on the control panel. In this
case the "Central Heating" (1) function
cannot be activated
E 182 Condensing unit alarm An anomaly appears on the condensing unit
e system does not work, see the
anomaly on the condensing unit and its
instructions booklet (1) (3)
E 183
Condensing unit in test
mode
A signal noties that the condensing unit is in test mode
During this time, room heating/air condi-
tioning and domestic hot water produc-
tion requirements cannot be met
E 184
Communication block
with condensing unit
A signal noties an anomaly due to a communication problem
between the indoor unit and the condensing unit.
Have the electrical connection between
the units checked (1) (3)
E 185 Communication alarm Communication anomaly between P.C.B. and ignition board.
Have the electrical connection between
the components checked (1) (4)
E 186 Igniter voltage anomaly An anomaly appears on the ignition board (1) (4)
E 187
Heat pump return
probe anomaly
e board detects an anomaly on the heat pump return NTC probe. (1) (3)
E 188
Request with tempera-
ture out of range
A heating or cooling request is made with an outdoor temperature
exceeding the operating limits (sect. 1.25)
(1) (3)
E 189
Time out alarm with
communication board
If communication between the printed circuit boards is lost, an
anomaly is signalled.
(1)
E 191
Zone 2 CAR Wireless
communication failure
If there is no communication between the indoor unit and second zone
Wireless version CAR, an anomaly is signalled. From this moment,
it is only possible to control the system by means of the control panel
of the indoor unit itself.
Check operation of the Wireless CAR,
check the battery charge (refer to the relative
instructions booklet).
E 192
Heat pump ow probe
anomaly
e board detects an anomaly on the NTC heat pump ow probe. (1) (3)
E 193 Appliance in test mode A signal noties that the appliance is in test mode e system continues operating properly
E 194
Condensing unit dis-
abled
A signal noties that the condensing unit has been disabled through
the appropriate input in the terminal board
e system continues operating properly
E 195
Liquid phase probe low
temperature anomaly
Too low temperature is detected in the liquid phase
Check proper operation of the cooling
circuit (1) (3)
E 196
High temperature block
on heat pump ow.
Excessively high temperature is detected in the ow circuit of the
heat pump.
Check the hydraulic circuit (1) (3)
(1) If the block or anomaly persists, contact an authorised company (e.g. the Authorised Technical Assistance centre).
(2) The anomaly can only be verified in the list of errors in the “Information” menu
(3) e heat pump does not start, the heat generator stays active to satisfy the room heating and domestic hot water production requests
(4) e heat generator does not start, the heat pump stays active to satisfy the ongoing requests
