The Nibe Temperature Limiter Stat – 518636 is used in various Nibe heating systems, It functions as a safety thermostat or temperature limiter, designed to prevent overheating by cutting off power if the system exceeds a certain temperature threshold.

Technical Overview

• Manufacturer Reference: 518636
• Type: Temperature limiter thermostat
• Function: Acts as a safety cut-off to prevent overheating in Nibe heat pump systems. If the system exceeds a critical temperature, this stat interrupts the circuit to protect components like the compressor or immersion heater.
• Reset Mechanism: Typically manual reset—once tripped, it must be physically reset to resume operation. This prevents automatic restarts in unsafe conditions.
• Mounting: Usually mounted on or near the immersion heater or compressor housing, depending on the model.
