Description

The Salus THB23031 Auto-Balancing Actuator is a precise, effective and easy to install way to provide automatic balancing of your underfloor heating circuits. Once fitted, this actuator will achieve the same results as hydraulic balancing but with a much quicker and easier setup process compared to conventional balancing. 

Ideal for new buildings, renovations and retrofits, this auto-balancing actuator works by continuously measuring the temperature and adjusting the actuator position to maintain the correct temperature differential between the manifold flow and return pipes. Comes with an IP54 rating to provide protection against contamination from limited amounts of dust and other particles. Additionally, it will be protected from water sprays from all directions.

Installation: The actuator arrives in the fully opened position for easy fitting. Simply attach the THB23031 to the underfloor heating manifold thermostatic valves on the return bar and ensure it is fully tightened. For full installation instructions, please see our Resources section.

  • Automatic, dynamic, hydraulic balancing
  • Very easy, install and you’re “done”
  • Ready to use without calibration
  • Two-colored LED lights (green/red) as status indicator
  • Continuously measures the temperature and adjusts position
  • Ideal for new buildings, renovations and retrofits
  • High precision thanks to the electronic motor
  • Fast valve opening and closing times
  • Optimal for use with heating or cooling

Code: THB23031

Easy to install and works wellReviewed by Davidcull on 05 Nov 2024

Replaced some standard non balancing actuators and worked well.

Hi, what is the difference between this and the IT500? Other than price on your website? We need a replacement IT500 touchscreen thermostat as our old one has broken. Which do we need? We have all the other bits.
The main difference is that the IT500BM is for combination boilers and single heating zones only. Otherwise, they are very similar products and can both be smart-phone operated.
Hi is this compatible with Baxi duo tec 28 boiler
Salus thermostats are compatible with all boilers
