Application
L4189 and L6189 are sensitive, immersion-type water
temperature thermostats for controlling and limiting boiler
water temperature in hydronic heating systems.
These thermostats are designed for panel mounting and are
supplied with a remote bulb and a liquid-filled sensing element
which fits into an immersion well (order separately) for
mounting into a boiler, tank or other vessel.
