Low speed: it switches on when the temperature of the coolant reaches 95°C.
High speed: it switches on when the temperature of the coolant reaches 100°C.
The speed of the electric fan also depends on the state of the three stage pressure switch for the climate
control system which determines the engagement of the first speed and, with a certain delay, that of the
second and the subsequent switching off.
