Location of the Transformer/Humidity Sensor unit
Page
6
The Transformer / Humidity sensor unit
may be mounted on the wall or ceiling.
Position the transformer / humidity unit
at least 6” (150mm) from a corner to allow
correct airflow over the humidity sensor.
Also, ensure the humidity sensor unit is
not directly in the stream of the fresh air
coming in from the fan unit, as this will
result in false sensing.
An ideal location is on the same wall, or
one immediately adjacent which is in the
stream of the stale / damp air being
drawn into the side vents of the fan
assembly.

Note: This part must not be mounted in
the interior of a bath tub or shower
basin and must be positioned out of
reach of a person using a fixed bath or
shower. It should be also positioned
away form any source of water spray.
Wiring:
IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN
Decide how you are going to run the wires from the transformer to the fan unit. All wiring must
be in accordance with current IEE wiring regulations.
A 5 amp two core power cable is required to connect the fan assembly to the remote control.
A two core, 3 amp supply is required on the input mains connection.
An earth connection is not required.
Pass the input and output wires through the cable hole in the base plate of the remote control
and fasten it in position. (
SEE DIAGRAM ON PAGE 2)
To comply with electrical safety regulations both input and output leads must be clamped to
the unit using the saddle clamps provided.
Mains wiring for remote control and transformer:
Red or Brown wire
to live terminal
Black or Grey wire
to neutral terminal
Do not apply power to the transformer yet!
No earth is required to the ventilator in accordance with IEE wiring regulations for SELV
circuits.
All wiring must be 1mm Minimum, fixing securely to comply with IEE wiring regulations. If in
doubt consult a qualified electrician.
