The Truma Frost Control is a safety device designed to protect water systems in caravans and motorhomes from frost damage.
It automatically drains the water heater when temperatures drop below approximately 3C, preventing damage from freezing. Suitable for Truma boilers, Combi heaters, and Trumatic C systems, it works with 12mm fixed pipe connections (John Guest System).
