The Nibe part number 718747 is a temperature limiter (a manual‑reset safety thermostat) used in several Nibe heat‑pump and hot‑water systems. It cuts power if the water temperature exceeds a safe limit, protecting the system from overheating.

What the Nibe 718747 Temperature Limiter Does

A temperature limiter is a high‑limit safety device. It is separate from the normal thermostat and is designed to trip only in abnormal conditions.

Key functions:

• Cuts power to the immersion heater or heating circuit if water temperature becomes dangerously high.

• Prevents overheating of the cylinder or heat‑pump hydraulic module.

• Requires manual reset once the fault condition is resolved.

• Protects against thermostat failure or wiring faults.
