Why not use their digital controller for the fans? A little more expensive but it is a nice unit. Nice job on the mount. I have used spal products in the past and always had good luck with their products.

 

Spal has been around for at least 40 years. Good stuff.

The pictures and fabrication look good. Let us know the final outcome.

 

Did not get it due to $$$. Thanks all. It should be ready today. will give you all the feedback once it is done and tested.

 

it is done the 195 fan runes for like 1 minuet and cuts off the second 185 on the return line doesn't come on, the temp dos not reach that hight. the first fan seams to be able to Hadlee it by its own.
the second fan (the 185) is connected to the A/C, so if I switch the A/C one the first dos not come on.
will do more testing and report back.
out side temp is 47 C (116 F).
