My STC-1000 does not turn on a heater when needed. What should the voltmeter read at the output terminals? I think open, (off) should be 120vac, closed (on) should read zero.
The controller I used last year reads zero, open or closed, and the heater never comes on. Same readings on a new controller. F3, delay time, is set at 3 min
What am I missing?
