My Troyer fan controllers bit the dust long ago, I want to replace them with the Delta Current ones but can't figure out which one I need, they all seem to only run one fan. I have emailed them a few times but got no response.
Can any one tell me what model I need to make my fans work?

thanks

 

are the troyer fans single speed or 2 speed?
if it was me i would just buy the cheap ones at the bottom the dfr-a or dfr-b depends if they are single or 2 speed fans though as to which controller if 2 speed you will need 2 dfr-a modules and if there only 1 speed fans then you can use just 1 dfr-b controller for both fans but they would both come on at the same time you wouldnt be able to have one for the a/c and rad temp and one work just for the radiator temp. but there site doesnt give any details of how these units operate and what makes them turn the fans on and off a/c clutch, rad temp, a switch it doesnt say.

 

Thanks for the advice, your's was the only reply.
