Dontek Solar Hot HD Digital Sensor 1.0m – Splicing Kit Included

Dontek Solar Hot HD Digital Sensor – 1.0m with Splicing Kit

Replace or extend your Dontek solar heating system’s roof sensor with the Dontek Solar Hot HD Digital Sensor. This high-definition digital sensor delivers precise collector temperature readings to your Dontek controller, ensuring your pool heating pump only runs when the sun is genuinely heating your panels — maximising efficiency and reducing wear.

The 1.0m cable version is ideal for installations where the sensor mounts close to the controller entry point, and the included splicing kit makes it easy to extend or join cables on-site without specialist tools.

Key Features

• HD digital temperature sensing for accurate solar control
• 1.0 metre cable length
• Splicing kit included for easy cable extension or joining
• Roof/collector (hot side) sensor
• Genuine Dontek replacement part
• Compatible with Dontek solar controller range

Frequently Asked Questions

What is the difference between this and a standard sensor?
The HD Digital sensor provides higher-resolution temperature data to your Dontek controller compared to standard analogue sensors, resulting in more precise pump switching decisions.

What is the splicing kit for?
The splicing kit allows you to join or extend the sensor cable on-site — useful when routing cable through walls, conduit, or over longer distances than the 1.0m cable alone allows.

Is this the roof sensor or the pool sensor?
This is the hot (roof/collector) sensor — it mounts on or near your solar panels. For the pool (cold) sensor, see our separate pool sensor listing.

Which Dontek controllers is this compatible with?
Compatible with the Dontek solar controller range including Aquasun, Aquasmart, Aquatek, and Supreme models. Check your controller manual if unsure.
