WIRING
IMPORTANT: ENSURE THAT THE MAINS SUPPLY IS SWITCHED OFF BEFORE
MAKING ELECTRICAL CONNECTIONS.
The PROFILE is an extractor fan designed for a single-phase supply, with voltage and
frequency as indicated on the rating plate of the unit. The units are manufactured with
double insulation (Class ll) and therefore do not require an earth connection.
Once the cable has been introduced through the cable entry point (2), proceed using the
electrical wiring diagram applicable to the selected model as follows:
•
PROFILE – 150 S
This model uses the following wiring diagrams:
Fig.3.
Fan operating through a light switch.
Fig.4.
Fan operating through an independent switch.
•
PROFILE – 150 T
Models fitted with adjustable timer.
The timer enables the fan to continue running for the selected period after the switch has
been turned off.

The desired run-on time is selected by means of an adjuster “T” positioned on the printed
circuit board (Fig.8), and is accessible once the grille (1) is removed.
•
To reduce the run-on time, turn anticlockwise.
•
To increase the run-on time, turn clockwise.
•
PROFILE – 150 HT
Models provided with an electronic humidistat, which can be adjusted from 60% to 90%
RH (relative humidity), and with a timer, adjustable between 1 and 20 minutes.
Operation
Case 1: Automatic operation (Fig.
4
).
The humidistat causes the extractor to operate automatically when the humidity level in
the room is higher than the set level. The extractor will stop automatically when the
humidity drops below the selected level and after the selected period, set on the timer.
Case 2: Automatic with manual override.
Automatic operation as in case 1, but with the facility to override the humidistat by means
of the light switch (Fig.6), when the humidity level in the room is lower than the selected
level. In this case, the extractor continues to operate for the period set on the timer, after
the light switch has been switched off.
