The Senztek SolaSmart Plus controller is a premium replacement controller designed for Edson solar hot water systems that are not circulating properly, failing to heat, or showing incorrect temperature readings.

If your Edson system is not working correctly, the controller is often the cause. This model restores reliable operation while improving system efficiency with advanced control features.

This is a common solar hot water controller replacement for Edson systems.

Common signs your controller needs replacing

• No hot water or poor heating
• Pump not turning on
• Incorrect temperature readings
• System overheating
• Inconsistent system performance

Why choose SolaSmart over SolaStat?

The SolaSmart Plus includes advanced features not found in standard SolaStat controllers, including:

• Smart Top-Out control for improved heat recovery
• Boost function for additional hot water when needed

This allows better energy efficiency and improved system performance compared to older controllers.
