New Addition for Residential Low Water Cut-offs

The new field-assembled harness allows the installing contractor to plug directly into the OEM’s wiring harness without cutting wires. This dramatically shortens installation time, saving time and money, and significantly reduces the chance for errors.

Two models are offered to accommodate different types of boilers. The UWH-RB-24-A is designed for most atmospheric boilers with 6-pin aquastats or vent damper manufactured by Effikal, Fields, Johnson Controls or Honeywell, while the UWH-RB-24-S is designed for sealed combustion boilers that use integrated burner controls from United Technologies or electronic aquastats from Honeywell. The M&M Series UWH-RB-24 wire harness kits can be applied to 80 percent of the 24-volt residential hot water boilers installed annually in the United States.

McDonnell & Miller, a unit of ITT Industries, is a leading manufacturer of boiler controls, flow switches, liquid level controls and steam specialty products for residential, commercial and industrial applications.
