Opened the door and the lights were off,checked my Titan controller,and it looked like it stopped 20 minutes after lunch lights came on.Went to check my electric panel,my 50 amp breaker popped so i knew something was up.I flipped it back ,lights came on then 15 minutes later breaker popped again.Ran to the room and there was a burnt smell and fumes coming from that controller.

Opened the controller and found that the red hot wire terminal was burnt.Very thankful there was no fire and also disappointed in this thing,it’s not even a year old.

Is it a problem with the timer, or something downstream from the timer? Perhaps a smaller breaker or slow fuse should be employed between the timer and main, and smaller individual fuses between the lights and timer.

Yes, On #19 in this thread, I'm mentioned that I brought the Titan back. Glad you're ok.

BTW this was a Titan Helios 7 which controls up to 8k lights with a built in timer.

Thanks Zeez,i am going to go to the store to get it exchanged,but have to wonder if this one was faulty or not?. I want to open it up completely but the sticker says “warranty void if opened”. I’ll ask the guy there if we can open it up just to see how far is the damage,cause i can tell that red lead on the inside was melted also.

What Guage of wire did you use, those ring terminals are only rated for 10AWG, 8AWG won't fit inside and allow you to crimp the wire.

I don't see any color coding on the ring terminals. I know they can be made for up to at least 4AWG. I have a few. However, I wouldn't rely on crimping alone for wire that large. I'd solder them also.

Is it possible the ground wire made contact with the hot wire?

[hvac guy]

Possible, looks like none of the ring terminals are insulated, that's why they were taped. Do you have ratchet crimps?

It looks like he didn't have the wires screwed down tight to me. I have the same controller and it's worked nonstop for 3 or 4 years. I think think it said in the instructions to check your connections once a year. You are also supposed to use 6 awg wire for that controller. I'll be sure and check that my connections are tight after seeing that.
