Samples
Before Trip
Number of ground current samples
read above trip set point before trip is
triggered. (does not affect time to trip
because the samples are microseconds
apart) This is to improve noise immunity.

Start Up Delay
Time in minutes before heaters turn on
for the first time after system power
