Replacement Solar Hot Water Tank Sensor to suit Apricus Senztek Controllers

The Senztek Tank sensor suits the full Senztek SolaStat, SolaSmart, AlphaStat range.


If you are just replacing the tank sensor on your system, we recommend you check the sensor port or immersion sleeve for moisture. If there is moisture, the sensor port or immersion sleeve will need to be replaced. This is mostly a problem in the older stainless steel hot water tanks. The original sensor port develops pin holes because it is the weaker metal.
Sensors are not designed to be installed in water and the moisture gives them an inaccurate reading. If you find moisture, check the roof sensor and the circulation pump first before ordering a tank sensor. Just because the pump motor is running does not mean it is circulating water as it should. With some models of solar hot water systems, your best option may be replacing everything at once with a complete pump station. Please contact us if you have questions about this before you purchase this item.
It is important that tank sensors are not used as roof sensors. Tank sensors are normally made from PVC cable and not high temperature silicone cable. Tank sensors are generally only rated to 90 degrees, whereas roof sensors can be rated two to three times higher.
Not all sensors are the same. This is a common mistake because over the years some manufacturers changed controllers multiple times. The thermistor inside the sensor gives different resistance levels with temperature change and the controller uses the reading to calculate the differentials required to operate the circulating pump.
There are many different types of controllers that use different types of sensors. If you are unsure, email us a photo of your controller and we can guide you to the correct sensor.



The image above is of the original sensor. The actual product supplied may differ to this but is an appropriate replacement part for your system. Images of the solar hot water controllers and original sensors are included in the description of products to assist you to find the appropriate product for your system (controller is not included in sale price).

Which Senztek controller do you have?

Senztek made several controller families, and the sensor you need depends on which one is fitted to your system. Check the badge on the front of the controller:

  • SolaStat / SolaStat-Plus — the most common solar circulation controllers, with a digital display. Available as 1-2 sensor, 1-3 sensor and 2-3 sensor versions.
  • SolaStat ST Plus — fitted to Apricus and several rebadged systems. Available as 1-2 sensor and 1-3 sensor versions.
  • SolaSmart / SolaSmart Plus — the later range, some fitted with a separate touch display. Available as the standard SolaSmart Plus, and in Edson and SolarArk versions.
  • SolaSmart Lite — used by Heavenly Solar and Solar Ark. Now discontinued.
  • AlphaStat-Plus — controls the electric booster element rather than solar circulation. View the AlphaStat-Plus.

The numbers in the model name are how many sensors the controller uses: a 1-2 runs two sensors (roof and tank), a 1-3 runs three, and a 2-3 will work with either.

Not sure which you have? Email sales@solarhotwaterparts.com.au a photo of the front of your controller and of the plug on the old sensor, and we will confirm exactly which sensor you need.
