Description
The Honeywell/Resideo L4006B1155 is a heavy‑duty immersion aquastat designed to regulate or limit liquid temperature in boilers, storage tanks, or circulator systems. Built for rugged use, this device helps maintain safe operation by turning on (making contact) as temperature rises, allowing users to set both the upper limit and the sensitivity of how quickly the control reacts via a differential range of 5‑30°F.
Features:
- Totally enclosed Micro Switch+ snap-acting switches operate on temperature rise to setpoint.
- Visible control point scale and external adjustment screw permit easy setting.
- Horizontal or vertical insertion of the sensing element.
- Direct or well immersion of the sensing element.
- Models available for strap-on mounting.
- Remote bulb model may be used to sense air temperature in ducts and in outside air sensing applications.
