Taco 120V low water cut-off (LWCO) with automatic reset and 3/4" probe. LTA-2 models are used on smaller hot water boilers (usually under 400,000 BTU). They are available in 24 and 120 VAC auto reset models; the LTA-2 has a compact full metal enclosure with direct probe mounting, a test button, external LED lights, and easy-to-wire tri-barrier terminals. Built with the same patented signal processing technology as the LTR, the LTA-2 is a great solution for upgrading the safety of current systems or when traditional 120 VAC hard wiring is required.
