Application
L4188 and L6188 are sensitive, immersion-type water
temperature thermostats for controlling and limiting boiler
water temperature in hydronic heating systems.
The thermostat has a liquid-filled sensing element which fits
into an immersion well (order separately) for direct mounting
into a boiler, tank or other vessel.
