• the second speed cuts in at a higher temperature threshold.

The operation of the fan is achieved by means of two special relays and a remote control switch located in the engine compartment junction unit.The fan supply line and the relay energizing circuit are protected by special fuses located in the above mentioned junction unit.The fans only come on when the ignition is switched ON.
