The Viessmann Contact Thermostat Temperature Limiter is a safety‑critical component designed to protect heating systems by monitoring and limiting the surface temperature of pipes or equipment. Featuring a built‑in temperature limiter and supplied with a 1.5‑metre factory‑fitted cable, this thermostat offers reliable over‑temperature protection for a wide range of Viessmann installations.

Engineered for fast, accurate response, the contact thermostat ensures that the heating system shuts down or reduces output when temperatures exceed safe operating levels. Its robust construction, secure mounting design, and pre‑wired cable make it easy to install and ideal for use in environments where safety, durability, and precision are essential.
