Description

Product Description

Resideo L4081B1047/U is an aquastat circulator and high-limit controller that regulates boiler and hydronic heating water temperature with a 130 to 240 °F set point range. It uses an immersion liquid-filled sensing element to actuate two SPST snap switches: a fixed 10 °F high limit and an adjustable low-limit differential of 10 to 25 °F. The unit mounts horizontally and includes a 3/4-14 NPT well spud for immersion installation.

  • Dual SPST control: separate high limit and circulator/low-limit switch with independent set points
  • Temperature control: 130–240 °F set point range; fixed 10 °F high-limit differential; 10–25 °F adjustable low-limit differential
  • Installation and ratings: immersion liquid-filled sensing element, 3/4-14 NPT well spud, horizontal mount, electrical ratings include 8 A @ 120 V AC and 5.1 A @ 240 V AC

Product Highlights

Dual SPST aquastat with 130–240 °F range, 10 °F fixed high limit, 10–25 °F adjustable low-limit differential, 3/4-14 NPT well spud
