Mr. Steam Board Aux LWCO Mr w/ Test - The Sauna Place

Mr. Steam Board Aux LWCO Mr w/ Test is a safety-focused low-water cut-off module engineered to protect steam generators from dry firing and heat damage. Purpose-built as an auxiliary LWCO board, it monitors water level and interrupts operation the moment supply drops below safe thresholds, preserving heaters, gaskets, and wiring integrity. The integrated test function lets technicians verify sensor response and shutdown logic on demand, simplifying commissioning and preventive maintenance before peak usage. Weighing just 1 lb, the compact board mounts cleanly in tight mechanical spaces, with clear connections that speed retrofits and keep enclosures serviceable. Designed for broad system compatibility, model BOARD AUX LWCO MR W/ TEST enhances reliability across residential and commercial installations, reducing nuisance faults, extending component life, and supporting code-conscious operation for a safer, longer-lasting steam system.

  • Low-water safety cut-off – Shuts the system down when water levels drop, preventing dry firing, heater damage, and nuisance trips. Proactive protection extends component life, reduces service calls, and maintains safe operation during irregular fill, supply interruptions, or startup.
  • Built-in test function – Provides a simple, on-demand test to verify sensor response and shutdown logic without disassembly. Fast checks streamline preventive maintenance, support commissioning, and give operators confidence that protection works before busy service periods.
  • Lightweight 1 lb design – Easy to handle and position during installation, minimizing strain in tight mechanical spaces. Low mass supports secure mounting on varied substrates and speeds retrofits or replacements while keeping enclosures uncluttered and accessible for future service.
  • Wide system compatibility – Integrates with a broad range of steam shower systems to enhance safety without compromising performance. Versatile connections and control logic support plug-and-play installs, preserving existing layouts while improving reliability across mixed equipment fleets.
