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.
