Electrical Repair Questions? Ask an Electrician for Answers ASAP
Hi! I was reading your dialogue with a Customer regarding how to wire the EE-TI, I have the same unit has he did and face the same exact challenge. :) I wish he had responded at the end to let you/us know! Did you ever get confirmation about where the white-wire goes? From what I can tell, the red and black lines from my 60Amp breaker would go into Line 1 and 2, but then where does the white wire go? Is it just the red and black + the copper ground wire that gets hooked up?
I do know that this is a 230V/Single Phase unit.
Wiring Diagram"/>Yes indeed! The high-voltage connections, of which I am confident that I have found 3 of the connections for this (Two into the Main Contactor, and one into the ground lug). I have attached pictures of what the inside of the unit looks like, as well as a better pic of the wiring diagram for the single-phase units.
Here's the rub; there's a 4th electrical connection that May be an output (for 24V), but I'm not 100% sure. (The 4th connection is a red wire coming out of the 24V transformer that has a screw-connector on it and nothing else (like it's ready for me to connect it to something). The picture and manual I'm about to upload has more details, and I greatly appreciate the help! I'l jack up the price, this advice is worth more than $30!
I'll take a pic of the power panel, doctor that up and upload it shortly. :)
Cheers XXXXX XXXXX!
Sorry! My bad. :)
Will stand by, here is last pic! This means alot to me, as I don't want to short-out the power panel again!
My pleasure, your advice is worth Alot to me. :)
Okay this makes more sense about the 2nd input, as the EE2500 has both a high-voltage and a low-voltage line ports connecting into the unit. To be honest I screwed this up the first time and connected a 115V line to that red-wire, which as I understand now is for 24V Input. :( When I did that the motherboard blew hard (the relays all snapped and then smoke came out of the voltage regulator on the power interface board).
So then I realized how badly I had failed, and ordered both a new power interface board and a new 24V transformer. The transformer has E-0191 written on the side, which I found on-line. The part about this wiring diagram that infuriates me is that there are no dotted-lines leading from that red wire to the edge of the diagram (which would tell me that it's an external input). I also don't know where I would connect the ground wire for the 24V supply. This is where I'm stuck.. :(
A pic of my power panel as a reference, and here is the link to the actual manual for my unit if you need... I'll tip on this too to bring it over $100, your time is worth it!!
I think your right, it wants 8 gauge wire at least (I'll have to run a new line, thats okay - as your right). The unit can run at 37 Amps normally with a maximum of 60 Amps - so I need a thicker gauge wire there...
At first I didn't have the red wire connected to the breaker, I've fixed that now so that both red and black wires are into the breaker.
Good catch!!! :)
Thanks for looking into this! :)
No worries at all, I have to put mine to bed soon too! :)
My understanding is that I need to add both a low and a high voltage lines to the heater. You've helped me understand the high voltage lines very well now (I'm such an idiot!), so the last question I think I have is how to connect the low voltage lines into the power panel.
Once I figure out how to drop the voltage to 24V from the 115/120V I get off the power panel, I Assume that the hot/white 24V line would go into that dangling red wire on the transformer, but where would I connect the Black wire from the low-voltage line? Or do I not even need one because the high-voltage line will suffice to ground both?
Or is it that I just need to wire a single 24V wire and connect it to the red dangling wire off the transformer and not care about the ground?
Again Jason, thank you Very much for your help and input on this!! I'm going to doctor-up an image of this power-panel with instructions for the next poor fewl like me who needs to wire one of these up!
As I understand it now, I would have run 8 or 6 gauge wire to the high-voltage inputs, which is the Red and Black wire that connects to the Main Conductor unit in the heater and to the 60Amp breaker on the other side. I cap the white-wire, connect the ground wire and it should be Good to Go!
I get the new power controller motherboard and transformer on Wednesday, so I'll try and wire things up then - and report back to you on how it went. :)
I'll rate this and tip you now, you have answered all of my questions very thoroughly! I do have one closing question actually that will round-out my understand of this - the Bonding wire. I assume that's actually a ground wire that connects to the pump and ground so they are "bonded"? Is that right?
Thank you again, and have a GREAT week!!
Your most welcome!
I'm sure that the economy doesn't help with people not being able to contribute much, but to me it's extremely fair to pay you $100 for this information! If you think about it, $100 is probably the profit margin that an electrician would get in a house visit after the company takes their share, gas and your time.
Plus if you consider that I just melted $300 worth of parts (and hoping to hell it's not More that I cooked)! If I had known about Just Answer, or more correctly, if I had taken the time to do the research that I did After I burned it out, I would have saved myself $200! :) As it stands, it cost me $400 for being over-confident in my knowledge, a lesson I will not soon forget.
What's even More funny is that I peeled-off the sticker on top of the chip on this power controller board that I burned out, and what do you know - its an Amtel! I know how to program on these, and in looking more closely I may have only burned-out the LN2676 voltage regulator on the board. I'm going to order one for $5 from Digikey and see if I can repair it for kicks. ;)
Stay tuned, I'll post a big update on Wednesday night. :)
