Haltech E6A - Manual (Page 86)

To use this function, you must have the following:
- an electric thermofan, fused and relay switched;
- E6A programming software and cable.
Install the wiring for the thermofan to one of the Auxiliary outputs as described in figure
17.4-1. Be sure that the relay contacts are rated higher than the current drawn by the
thermofan.
Run the E6A programming software and go to the Options page. Select the Thermofan
function on the appropriate output and set the two temperatures as required.
Switch On Temperature: The temperature the engine coolant must exceed to switch the fan
on.
Switch Off Temperature: The temperature the engine coolant must drop below before the
fan will be switched off. This parameter should be at least 5° lower than the Switch On
temperature to prevent the fan from switching in and out repeatedly.
16.6 Electric Intercooler Fan Control (IF)
This function can be used to switch on an electric fan on the intercooler when the inlet air
temperature exceeds a certain value. The fan will stay on until the temperature drops below a
second value.
NB: The electric fan cannot be driven directly by the ECU. A relay must be used to switch the
high currents drawn by the fan.
To use this function, you must have the following:
- an electric fan, fused and relay switched;
- E6A programming software and cable.
