Honeywell High And Low Limit Aquastat Controller - L4081A1023/U

The Honeywell High and Low Limit Aquastat Controller is engineered for high limit and low limit applications, with a fixed high limit of 10 degrees Fahrenheit and an adjustable low limit ranging from 10 to 25 degrees Fahrenheit. The controller is designed with a 1-1/2 inch insulation depth and a Single Pole Single Throw (SPST) switching action, facilitating its horizontal mounting capabilities.

The Aquastat Controller is characterized by its immersion-type, liquid-filled sensing element, which actuates two snap switches. These switches independently operate at their respective temperature settings: one acting as a high limit control, and the other as a low limit and/or circulator control, depending on the model.

This controller is engineered for ease, with the ability to be mounted in any position without the need for leveling. Its design includes separate, easily readable, calibrated dials, and set point adjustments for each switch. All the adjustment controls can be conveniently accessed from inside the front cover.

The Aquastat Controller simplifies connection with push-in terminals and has a single sensing element for easy installation. In addition to two SPST snap switches, models L6081A and C also incorporate one Single Pole Double Throw (SPDT) switch.
