Now about the CT410B t-stat ... I mentioned that I kept blowing my circuit breaker when I had it wired in. I should describe how I had wired it and perhaps you can tell me where I went wrong. The CT410B is a 4-pole model (the 410A is 2-pole) and it has the following connectors:
L1 (black wire)
T1 (black wire)
L2 (red wire)
T2 (red wire)
I had connected black power supply to L1, connected the two reds L2 and T2 together with a cap, and then connected my black feed to the heaters to T1. I did it this way because it seemed similar to my old White-Rodgers t-stat. But it shorted out so I guess that wasn't quite right.
Looking again at the wiring diagram, I'm guessing that I should have run black supply to L1, white supply to L2, and then T1 back to feed the black heater wires and T2 to feed the white heater wires. This would be a slightly different setup that I currently have. So I'm just looking to see if I have correctly understood the wiring diagram. I'd still rather get a programmable model if I can find one that handles 4000 watts.  |
