The relay
J35 controls the heater
fan circuit
The supply for the relay contact arrives
from the battery through the line for the maxifuse
J/B1
of
B5
protected by fuse
F12
for the junction
unit
B1
, whilst the energizing of the coil is controlled
by the ignition (INT/A) through the line protected by fuse
B27
.
The relay
J35 supplies the control
knob H81: this controls the fan at the different
speeds via the regulator O30.
The voltage signal varies according to the
position of the knob and through the resistance of the regulator
O30 determining four different voltage signals for the fan N85 which sends outside or recirculation air to he duct/distributor
unit at 4 different speeds.
The control panel has ideograms which are
lit up, when the side lights are on, by lights
G45, supplied
by the line protected by fuse F3 for the junction
unit B1
(
