Description Technical Info Video Manuals

The Senztek SolaStat-Plus 1-2 solar hot water controller is a reliable replacement for systems that are not circulating properly, failing to heat, or showing incorrect temperature readings.

If your solar hot water system is not working as it should, the controller is often the cause. This model is designed for systems using two sensors and restores accurate temperature control and pump operation.

🔧 ✔ Common signs your controller needs replacing

  • No hot water or poor heating
  • Pump not turning on
  • Incorrect or fluctuating temperature readings
  • System overheating or shutting down
  • Intermittent or unreliable operation

🔧 ✔ Compatible systems

This controller is commonly used in systems including:

  • Apricus solar hot water systems
  • Hills systems
  • Dux solar hot water systems
  • Chromagen systems
  • Other systems using Senztek 1-2 controllers

🔧 ✔ What this controller does

Senztek SolaStat controllers automatically control the circulation pump by comparing temperatures between the collector and tank, ensuring efficient heat transfer and system performance.

🔧 ✔ What you receive

  • 1 x SolaStat 1-2 WR Controller
  • 1 x 3m tank sensor
  • 1 x 20m roof sensor
  • Thermal paste and connectors

🔧 ✔ Why choose this controller?

  • Proven reliability in Australian solar hot water systems
  • Simple plug-and-play installation
  • Pre-set settings for easy setup
  • Suitable replacement for older Senztek controllers
  • Widely used by plumbers and repair technicians

🔧 ✔ When this controller is suitable

  • Replacing an existing Senztek 1-2 controller
  • Systems using 2 sensor configuration (roof + tank)
  • Faulty or ageing controller

🔧 ✔ When it may NOT be suitable

  • Systems using 3 sensors (1-3 or 2-3 models)
  • Systems requiring inlet sensor control
  • Unknown or modified systems

🔧 ✔ 1-2 vs 1-3 controllers 

The Senztek 1-2 controller uses two sensors (roof and tank), while 1-3 models include an additional inlet sensor.

If your system originally had three sensors, you will need a 1-3 controller instead.

❓ FAQs 

Is this a replacement for my Senztek controller?

Yes, if your system uses a 2-sensor configuration, this controller is a suitable replacement for Senztek 1-2 models.

How do I know if I need a 1-2 or 1-3 controller?

Check how many sensors your system has. A 1-2 controller uses two sensors, while 1-3 systems use three.

Can I install this myself?

Installation is straightforward, but a licensed tradesperson is recommended to ensure safe and correct setup.

Do I need to replace the sensors as well?

This controller includes sensors, and replacing them at the same time is recommended for best performance.
