L4064B FAN AND LIMIT
CONTROLLERS
Longer, more active bimetal
reacts quickly to temperature
rise for superior temperature
sensing. Sensing element
in L4064 is designed for
maximum exposure of the
element to plenum conditions,
helping insure the furnace
continues to meet ANSI and AGA standards
for maximum 200° F plenum temperature.
Manual fan switch on selected models allows
continuous fan for optimum operation of an
Electronic Air Cleaner.
