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.

Sensors what this controller needs

The SolaSmart Plus uses three sensors: ROOF at the collector, TANK at the upper tank and INLET at the lower tank. All three sensors are supplied new with the controller.

• Replacing a SolaStat 1-3? Your system already runs all three sensor positions, so this is a straight swap.
• Replacing a SolaStat 1-2? Your system has only roof and tank. The inlet sensor is included in the box, but it will need to be run to the lower part of the tank during installation.

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• Your current controller is outdated or inconsistent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)
