(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
Cause
This happens when an incompatible remote control is connected
or when communication between the hydronic module and second
zone CAR is lost.
V2
A signal notifies that the condensing unit is in test mode
A signal notifies an anomaly due to a communication problem
between the hydronic module and the condensing unit.
A request is made with the outdoor temperature exceeding the
operating limits (parag. 1.12)
If communication between the printed circuit boards is lost, an
anomaly is signalled.

Hydronic module status / Solution
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.
The system does not work, see the
anomaly on the condensing unit and its
instructions booklet (1)
During this time, room heating/air condi-
tioning and domestic hot water produc-
tion requirements cannot be met
Have the electrical connection between
the units checked.
The system does not start (1).
