The Honeywell Resideo L4006A2015/B is an SPST high or low-limit aquastat controller with a 100 to 240°F (38 to 116°C) operating temperature range. This device includes a plastic bag of heat-conductive compounds.
The aquastat controller is an immersion type that limits and controls liquid temperature. This features a totally enclosed Micro Switch snap-acting switch that operates once the circuit breaks on temperature rise to a setpoint.
The L4006A model series is suitable for applications that utilize wells such as boilers and storage tanks. It is available for insertion in vertical or horizontal immersion well or direct immersion and surface mounting.
Note: A separate high-limit controller must be used when using the component as a low-limit controller.
