Honeywell L8100 Aquastat® Controller

Aquastat® Controller
L8100

L8100A,B, and C are immersion type controllers for regulating and limiting the tank temperature in water heaters. As the water temperature rises past the setpoint, the controller switches off the gas valve.

• Regulates temperature and provides energy cutoff (ECO) action on a temperature rise past the setpoint.
• Includes a second sensing element that senses average water temperature to minimize stacking.
• Fluid-filled element operates Micro Switch® SPST snap-acting switch.
• ECO switch interrupts the thermocouple circuit or main valve before tank reaches 210 F (99 C) maximum temperature.
• Includes factory-installed immersion well on controller.
• Internal adjustment screw.
• Special switch terminal provides three-wire hookup from Aquastat® controller to gas valve.
