Ascon Solar Pool Heating Roof Sensor

☀️ MS3D Roof Sensor – 20m Lead

Reliable temperature sensing for solar pool heating systems

A purpose-built sensor designed for use with the Associated Controls MS3D solar controller, this component ensures accurate roof temperature readings to optimize solar heating performance. The extended 20-metre lead makes it ideal for installations where the controller is located far from the roof sensor point.

🛠️ Product Highlights

• ✅ Controller Compatibility: Specifically designed for MS3D solar controllers
• 📏 Cable Length: 20-metre lead for flexible, long-distance installations
• 🔄 Error Resolution: Replaces faulty sensors that trigger the “RRR” error code
• 🇦🇺 Australian-Made: Available through NCS Pool Heating & Filtration Systems

⚠️ Understanding the “RRR” Error Code

When your MS3D controller displays “RRR”, it typically means:

• The roof sensor is disconnected, damaged, or has failed
• Replacing it with a compatible sensor—like this 20m version—can restore full functionality
