Low Water Cut-Offs by Taco

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

The Taco LTR Series Low Water Cutoff (LTR) is a microprocessor-based low water cutoff for detecting the presence of water in a boiler that provides reliable protection for residential and light commercial hot water boilers. It uses advanced signal processing to identify when the probe signal levels have decreased due to possible fouling. Thanks to these technologies, the LTR functions longer without requiring annual probe cleaning and maintenance and it functions normally under non-ideal installation conditions. A convenient, all-in-one design containing test button, plug n' play wiring harness and instant feedback maintenance LED lights.

Features Include:
  • One-piece sealed design for use with residential hot water boilers.
  • Test button to quickly verify correct installation and wiring.
  • Extended probe impedance sensitivity to 40K Ohms.
  • LED indicator lights: Green-to-red to indicate when boiler water level is low; amber LED to indicate when probe needs cleaning.
  • 24 VAC wiring harness.
  • Automatic reset when water level returns to safe level.
  • Compatible with gas-fired and oil-fired residential boilers.
  • Ideal for use with smaller high efficiency boilers
