Tom,
Thank you very much. I did the reset process (unplugged, turned off sales switch, turned off inverter on smart panel, then took 3 pigtails apart and the fuse). Waited 45 minutes and put it back together an no win.
Started live checking the printed circuit board and found CB4 had power in, but Rly4 had no power out. All the others did. So I swapped Rly3 and Rly4. Then tested the power outlet behind the water heater and it was hot 124V! Yeah.
I then put them back to original wiring. I then went to my control panel and took it apart and checked continuity on the 120V heater switch and found it tested out fine (It does light up when on too). I also jumped the 12v wire to the out 12v and it didn't make any difference on the output of Rly4. So, looks like a bad relay.
So, Now, what are my options?
It is a Intellitec distribution panel model 750.
I can only think of these two options...
1) See if I can buy a new printed circuit board? Haven't found the exact one yet, but looking to be around $300 - $400. The bottom picture below says they don't sell the model 750 and I would have to change to Model 900. Does that mean I would have to buy all 4 items listed below?
2) Bypass the relay and go direct from the 20A circuit breaker? Then, turn the circuit breaker off when I don't want electric hot water in the main panel instead of at the control center? Anything wrong with that? It really just turns that outlet off or on remotely like the salesman switch, right?
Thanks,
Greg
