Dontek Cold Temperature Solar Sensor TS02

Introducing the Dontek Cold Temperature Solar Sensor TS02 — a purpose-built sensor designed to deliver dependable cold-weather readings to your solar controller, ensuring your system responds correctly as temperatures dip.

Specifically engineered to integrate with Dontek V2, AS2, AS3, and AS5 controllers, the TS02 provides a straightforward upgrade path for existing installations and a reliable option for new builds in cooler climates.

What makes TS02 stand out

• Direct compatibility: Works seamlessly with Dontek V2, AS2, AS3, AS5 controller families, so you can trust accurate data without custom adapters.
• Easy, secure mounting: Requires a 14.5mm PVC pipe hole size for the rubber grommet, creating a snug, weather-conscious seal that minimizes exposure to the elements.
• Protective plug included: Fitted with a small blue plug as part of the assembly, simplifying handling and installation logistics.
• Designed for cold conditions: Optimized to monitor low-temperature environments common in cold-season solar setups, helping your controller trigger correct control strategies.

How it helps in real-world setups

- Residential solar hot water systems in winter: by accurately sensing cold temperatures, TS02 helps prevent unnecessary pumping or heating activity when readings are outside the desired range.

- Outdoor solar installations: a compact, purpose-built sensor that fits through standard pipe mounting points, reducing wiring complexity and preserving a clean installation footprint.

- Retrofit projects: swap in the TS02 to modernize older Dontek-controller-based systems and gain improved cold-temperature sensing without changing the controller.

Practical tips for best results

• Verify the mounting hole size on the solar installation before fitting; the TS02 requires a 14.5mm PVC hole with a rubber grommet for a proper seal.
• Consult your Dontek controller's wiring documentation for the exact sensor connection points and any required calibration steps.
• The blue plug is part of the assembly and contributes to straightforward handling during installation.

Who should consider the Dontek TS02

Ideal for solar technicians, installers, and DIY enthusiasts who rely on dependable cold-temperature data to drive efficient solar heating or hot water systems in cooler climates. If your setup uses a Dontek V2, AS2, AS3, or AS5 controller and you need a sensor that performs reliably in cold conditions, the TS02 is the right choice.
