L4191 - L6191 DUAL AQUASTAT - DIRECT IMMERSION
APPLICATION AND ORDERING INFORMATION
Application
L4191 and L6191 are dual units in which two independently
working water temperature thermostats are housed in one
cover. Each thermostat has a separate liquid filled sensing
element which fits into a common immersion well for direct
mounting into a boiler, tank or other vessel. One thermostat,
with external temperature setting dial, acts as a controller
while the other, with internal setting dial, acts as a high limit
control.

Two main types are available, one with controller and auto
recycling high limit and the other with controller and high limit
with manual reset.
