Ext.signal
It is present only if the fan speed control is configured with an external 0-10V analog signal (Installer
menu).
ok The external signal source works properly
ko
External signal not present (voltage at the clamps = 0V):
1) check electrical connections of the external source (see electric diagram);
2) if the problem is not solved, check whether the external signal is present (tester) and its
value is greater than 0V;
3) if the problem is not solved, replace the electronic card.
