Re: (ET) RE: Installing Landis controller in an Elec-Trak E-20
Mea culpa and confirmation. I must admit, last night, I went out and
checked on
my controller/timer combo. Late at night, batteries boiling, my timer was
already halfway through a cycle that I didn't start, and the bottom of the
timer
was hot when I unplugged the charger and unwired the timer.
Indeed, the timer IS starting on its own in this situation.
