QXD is a centrifgual fan for built-in installation, designed to ensure air extraction in small/medium-sized rooms
such as bathrooms, toilets and kitchens. Suitable for air discharge through long length ducting. Main extraction
through front cover, additional extraction though side inlet (fig.1).
introduction
technical sPeciFications
standard
The fan is operated using a separate ON/OFF switch or via a light switch (fig. 16A-16B).
With tiMer (over-run)
The fan is provided with a timer circuit which is adjustable from aprox. 1 minute to 25 minutes via trimmer
(fig. 17C). Operation: connected according to the diagram in fig. 17A-17B, after the light is switched on, the
fan activates with a delay of max 1.5 seconds. After the light is switched off, the fan continues to function
for a pre-set period of time.
With huMidistat & tiMer
The fan is equipped with a humidity detector, whose threshold is adjustable from 50% to 95% Relative
Humidity, and with a timer which is adjustable from aprox. 1 minute to 25 minutes via corresponding trimmer
(fig. 17D). Turn the trimmer HY completely clockwise and the humidistat function is deactivated.
Automatic humidistat operation: connected according to the diagram in fig. 17A-17B, when the percentage
of Relative Humidity exceeds the pre-set intervention threshold, the fan starts up automatically. When the
percentage of Relative Humidity goes below the threshold, the fan continues to function for a pre-set period
of time.
Operation with switch connection: connected according to the diagram in fig. 17A-17B, after the light is
switched on, the fan activates with a delay of aprox. 1.5 seconds. After it is switched off, the fan continues
to function for a pre-set period of time.
attention: when the relative humidity level is higher than the pre-set threshold, automatic operation with
humidistat has priority over manual operation, or rather the fan cannot be stopped via switch.
