2 5 minutes after switching
on the control unit, all zone
LEDs start to flash and all
grilles are closed Incorrect settings ·
Check the settings of the thermostats.
Make sure that they are
to the con-
trol unit .
·
Repeat the learning process.
·
In Radio systems, check whether it works at

·
In Radio systems, check the operating fre-
quency between thermostats and central are
the same.
3 Some of the zone LEDs do
not light up and the rest do Learning error
·
The thermostat corresponding to the
LED switched off has not been recognised

·
Check that the regulator is not obstructed.
9 All grilles are operating
correctly, but the climate-
control unit does not work Climate-control
until incorrectly
connected
·
Check the control unit settings according to
