Resideo L8100B1128

High-limit Aquastat® controller operates at 100 F to 180 F with 39 in. long capillary

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.

Specifications:

• Insulation Depth: 1-½ in.
• Bulb Size: ⅜ in.
• Capillary Length: 39 in.
• Switching Action: SPST, contacts break on temperature rise.
• Electrical Ratings (millivolt): 2A maximum at 24 Vac.
• Differential Temperature (F) Controller: 5 F, fixed.
• Energy Cutoff Switch: 20 F, fixed.
• Maximum Ambient Temperature (F) Maximum Tank: 210F
• Temperature Rating (ECO) Energy Cutoff: 200 F
• Mounting: Immersion Well

Features:

• 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.
