6.3 Wall duct for insertion of connecting lead of ventilation unit
Feed the electric connecting lead of the ventilation unit (see
view from
room side) into the wall duct.
Check the correct position of the wall duct (overhangs
outside / inside) and close the openings of the wall duct with
the protective covers.
Finally, fill the cavities (if any) between the wall opening and
the wall duct with non-pressurized
expanding foam.
7. INSTALLATION OF ELECTRONIC CONTROL SYSTEM
The electronic control system of Fox up ventilation units
is designed to be installed in a double hollow cavity
flush-mounted box. It can be used to control up to six Fox
up ventilation units.
The electronic control system is to be connected as statio-
nary equipment with fixed wiring.
See page 9 for electrical connection diagram.
The supply voltage of the electronic control system is 230 V/50 Hz. A light-plastic sheathed cable 3 x 1.5 mm2 (e.g. NYM-J 3 x 1.5 mm2) is
recommended as an incoming line.
The ventilation units are supplied by 12 V DC in combination with a PWM controlling signal. Therefore, the ventilation units should not under
any circumstances be connected to the 230 V mains voltage of the electronic control system. A light-plastic sheathed cable 3 x 0.25 mm2
(e.g. LiYY 3 x 0.25 mm2) is recommended as a control line for the ventilation units with a maximum length of 10m.
