Aquastat High Limit Electric with Sensor 100-180 Degrees Fahrenheit Controller/Fixed Energy Cut Off Switch 5/20 Degrees Fahrenheit Immersion Well

L8100 are immersion type controllers for regulating and limiting the tank temperature in water heater and hydronic systems. 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 SPST, Micro switch snap-acting switch
• ECO switch interrupts the thermocouple circuit or main valve before tank reaches 210 deg F maximum temperature
• Internal adjustment screw
• Special switch terminal provides three-wire hookup from Aquastat controller to gas valve
• 200 deg F energy cutoff, 210 deg F max tank temperature
• Electrical ratings: Mv-2 A max at 24 VAC
• Contacts break on temperature rise
• 39 in L capillary
