relay?

[harshman]

Out of curiosity what kind of controller are you using?

Derale. I talked to 'em last night and was told that although their controller is set up to control the second fan, the fans that I have require another relay (50 amp draw) - aka another controller. I installed the second one this morning and they seem to be working fine. I’m a bit irritated that I spent $50 for each controller just because of the size. Live and learn.
