Anomaly signalled
Cause
Hydronic module status / Solution
E181
Loss of communica-
tion with the CAR
V2
(zone 2)
This happens when an incompatible remote control is connected
or when communication between the hydronic module and second
zone CAR
V2
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) mode cannot
be activated.
E182
Condensing unit alarm
An anomaly appears on the condensing unit
The system does not work, see the
anomaly on the condensing unit and its
instructions booklet (1)
E183
Condensing unit in test
mode
A signal notifies 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
E184
Communication error
with condensing unit
A signal notifies an anomaly due to a communication problem
between the hydronic module and the condensing unit.
Have the electrical connection between
the units checked.
The system does not start (1).
E188
Request with tempera-
ture out of range
A request is made with the outdoor temperature exceeding the
operating limits (parag. 1.12)
The system does not start (1).
E189
Time out alarm with
communication board
If communication between the printed circuit boards is lost, an
anomaly is signalled.
