cabinet of the 50FF/FC unit.
Make the electrical connection of the probe (S3)
to the connection box "BOX8-QUE" that is located
inside of the 50FF/FC unit, using 2 x 1mm
cable.

minimum from the outlet mouth at the bottom of the duct and
as near to the middle as possible inside this duct. The probe is
connected to the air duct using the special fastening bracket.
