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.
