L4103A1019 High Limit Aquastat Controller with 100 F to 240 F operating temperature and 7 F ¦4 F Differential
The L4103A is an immersion-type controller for oil-fired water heaters. The Aquastat® Controller senses water temperature and cycles the burner through the oil primary. The high-limit controller breaks the circuit to the burner on a temperature rise past the factory-set setpoint.
• L4103A,B,C have a sensing element and a high limit sensor with automatic reset.
• Mounts on a horizontal immersion well in water heater wall.
• Adjustable temperature setting scale.
• Fluid-filled element operates SPST, Micro Switch™ snap-acting switch.
• Integral, nonadjustable high limit. L4103C is an immersion controller for gas systems.
• L4103A,B is an immersion controller for oil systems.
