BackyardBuild Posted August 30, 2012 Report Share Posted August 30, 2012 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 Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted August 30, 2012 Report Share Posted August 30, 2012 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.

augusto Posted September 3, 2012 Report Share Posted September 3, 2012 The air conditioning system operates with pressure. And not with engine temperature. You must use a pressure switch to control the electric fan. Augusto. Quote Link to comment Share on other sites More sharing options...
