Re: (ET) RE: Installing Landis controller in an Elec-Trak E-20

[Jeremy Gagliardi com]

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.
