The lowest thermostat setting is 90F so I didn't bother trying that. It required rearranging or removing every wire but one, but I did get the lower element powered and working, and am about to take a at-least-warm shower. Thanks again. I wasn't sure that I'd managed to keep the thermostat the circuit, but after looking at the photos I took several times, I can see that even if the connection up top is a constant 240 volts, the thermostat for the lower element is trill in the circuit.
The weird thing is that the dead heating element on top tests ok. No short, resistance in the prescribed range (12.7) and since the element was powered, the high limit hadn't been tripped. Maybe it just got tired of its career...
