GP aux out for Engine fan & AC ??

Recommended Posts

I am trying to get the cooling fan to operate under 2 conditions (ECT & AC request). I have searched the forum for a solution to my cooling fan issue. I found that using a general purpose output can have up to 3 conditions, but I cannot find a condition for AC request (wired to DI-2). The options are DI Value or Speed DI-2. How can I set this up so that the cooling fan operates under these 2 conditions?

Thanks, Tim

What Auxillary output have you got the fan wired to.

EG: if you have the fan wired to Aux Output 1,

Go to that Aux output 1 tab and select it's function as A/C fan.

You will then also have the ECT ON/OFF selections available , under that same tab.

The air conditioning system operates with pressure. And not with engine temperature.

You must use a pressure switch to control the electric fan.
