Beside the voltage from the electrical connection, which I understand just heats a bi metal strip faster, won't the bi metal strip operate the same way when subjected to heat and cold, only slower?
Is there a way to test the electrical connection too to ensure proper power is getting to the valve? I have a pretty good multimeter, but need some guidance as to what setting I should put it on for testing?
