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

If your solar hot water system is not working correctly, the controller is often the cause. This model provides advanced control features to restore efficient and reliable operation. This model improves system efficiency and reduces reliance on electric boosting.

This is a common solar hot water controller replacement for older or faulty Senztek SolaStat models.  The SolaSmart Plus is an advanced upgrade over standard SolaStat controllers, offering improved control and efficiency.

✔ SolaSmart vs SolaStat controllers

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

It is ideal for users wanting improved performance and energy efficiency compared to standard controllers. 

✔ Not the same as other Senztek controllers

  • SolaSmart → advanced solar circulation control
  • SolaStat → standard solar circulation
  • AlphaStat → electric booster control
  • Reclaim → heat pump control

✔ Common signs your controller needs replacing

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

✔ When to choose the SolaSmart controller

  • You want improved system efficiency and performance
  • Your current controller is outdated or inconsistent
  • You want better heat recovery (Top-Out function)
  • You want additional hot water control (Boost function)

✔ Compatible systems

Commonly used in:

  • Apricus
  • Hills
  • Dux
  • Chromagen
  • Bosch
  • Systems using Senztek controllers 

✔ When this controller is suitable

  • Replacing Senztek SolaStat controllers
  • Systems requiring improved performance
  • Faulty or ageing controller 

✔ When it may NOT be suitable

  • Systems requiring simple 1-2 or 1-3 replacements
  • Systems with fixed sensor configurations only
  • Non-Senztek controller systems 

✔ Not the same as AlphaStat or heat pump controllers

  • SolaSmart → solar circulation control
  • AlphaStat → electric booster control
  • Reclaim controller → heat pump systems

 This helps maximise solar energy capture and reduce reliance on electricity.
