Temperature sensor NTC for hydraulic clutch Viessmann 7179488

NTC temperature sensor for hydraulic clutch compatible with Viessmann systems. This replacement sensor uses a negative temperature coefficient thermistor to measure temperature and deliver analog resistance feedback to control electronics. It is intended to restore accurate temperature monitoring and regulation in heating and hydraulic assemblies where the original sensor is worn or defective. The compact design and standard electrical characteristics allow integration into the clutch housing and connection to the boiler or controller circuits.

Advantages

The sensor provides reliable temperature-dependent resistance change with fast response time and stable operation in typical heating system environments. Its design supports straightforward replacement without modifying surrounding components, ensuring continued function of control and safety circuits. Constructed to meet the physical and thermal demands of hydraulic clutch assemblies, the sensor maintains measurement accuracy across the normal operating temperature range of residential and light commercial boilers.

Suitable for

• Replacement of a failed or aged clutch temperature sensor in Viessmann heating systems
• Repair and maintenance of hydraulic clutch assemblies in boilers and heat generators
• Applications where NTC thermistor feedback is required by the control electronics

Key specifications

• Sensor type: NTC thermistor (negative temperature coefficient)
• Function: temperature measurement and resistance output for control circuits
• Application environment: hydraulic clutch and heating system assemblies
• Form factor: compact probe suitable for clutch housings
• Operating temperature: range suitable for boiler and hydraulic clutch operation

How to use

Switch off power to the heating system and allow the unit to cool before attempting replacement. Access the hydraulic clutch housing according to the manufacturer's service instructions, extract the defective sensor, and install the replacement sensor in the same position and orientation. Reconnect electrical leads following the original wiring scheme, ensuring secure contacts and correct polarity where applicable. Restore power and verify temperature readings and control responses with the boiler or controller diagnostics to confirm correct installation.

Usage recommendations

Use only when the system is cold and powered down; follow Viessmann service guidance for access and safety. Check resistance values at known temperatures if possible to confirm the thermistor characteristics before reassembling. Replace seals or gaskets disturbed during service to retain hydraulic integrity.
