Low Water Cutoff and Water Feeders

Product > Electronic Controls > Low Water Cutoff and Water Feeders


The Taco Low Water Cutoff (LWCO) provides accurate and dependable protection for all types of boilers, from small residential hot water boilers to large industrial steam units. The LWCO is a probe-style, microprocessor-based control that detects the fluid level in hot water and steam boilers and reacts when the level falls below the minimum safe operating level specified by the boiler manufacturer.

The Taco LWCO can act as either the primary or secondary low water cutoff on low-pressure steam boilers, the primary limit control on hot water boilers or to protect pumps from running dry in condensate receiver tank applications. The LWCO can also activate alarm systems or automatic water feeders.

Features include:
  • Patented Adjustable Probe Sensitivity
  • External LEDs and Simplified Wiring for Easy Installation and Testing
  • Automatic or Manual Reset Mode
  • Available in 24 VAC or 120 VAC
  • Standard On-Board (NEMA 1) or Remote (NEMA 4) Probe
  • 1/2” or 3/4” NPT Connection
  • LT Models Include External Test Button, Adjustable Delay On Break (DOB) and Delay or Make (DOM) Features
