L8100A,B, and C are immersion type controllers for
regulating and limiting the tank temperature in water heaters.
As the water temperature rises past the setpoint, the
controller switches off the gas valve.
FEATURES

L8100A regulates tank temperature and provides
energy cutoff (ECO) action on a temperature rise past
the setpoint.
•
L8100B regulates temperature and provides ECO
action on a temperature rise past the setpoint. This
model includes a second sensing element that senses
average water temperature to minimize stacking.
•
L8100C includes a second sensing element that
senses average water temperature to minimize
stacking, but does not include ECO action.
