Functional description

The relay J35 controls the passenger compartment air 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 outside/recirculation air intake flap motor N82 is operated by a special button, located in the control panel H80: the operation of the button sends an earth signal and a supply controlled by the ignition (INT/A) protected by fuse B27 which are reversed to reverse the direction of rotation of the motor. 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 ( See E2010 SIDE LIGHTS / NO. PLATE LIGHTS ).
