Wiring is suspect.
Black hot wire connects to dark screws.
Break off tab should be intact.
White neutral wire connects to silver screw.
Wire going to switch load connects to brass screw.
Instructions given are 100% correct for wiring TR274. The Cooper blurb saysTR274 has single-pole switch and pilot light is only ON when switch is ON. If product is defective, contact Cooper 866-853-4293.http://waterheatertimer.org/How-to-wire-...
