Power Stealing
Power Stealing is an electronic design within the control that
can eliminate the need to connect a neutral line to power the
control. The control receives power from the unit it is control-
ling. Power Stealing saves time and money by often eliminat-
ing the labor to run a neutral wire to the control for power. See
compatibility chart below for certain limitations.
