The Salus THB23031 – Ultra THB – auto-balancing actuator is used to regulate surface heating and cooling systems. The unique built-in automatic balancing control ensures each circuit is always correctly balanced. The actuator is attached to the manifold, opening and closing the valve in the return port. This is operated by the signal sent by your wet underfloor heating thermostat or wiring centre.

The Salus THB23031 auto-balancing actuator has two temperature sensors. They are connected to the flow & return pipes or the inlet and outlet of the manifold.  The auto-balancing actuator will adjust the actuator position to maintain the correct temperature differential between the flow and return pipes

Installation
Below are the steps to connect your actuator to a VPS manifold.

• The Salus THB23031 is fitted on the return bar of the manifold. Placed above each return port for individual control.
• Remove the blue flow cap and expose the actuator valve.
• Attach the actuator to the underfloor heating manifold thermostatic valves. Place the unit onto the valve and screw the ring nut onto the valve thread.
• Attach the two pipe sensors, one on the flow pipe and the other on the return.
• Connect the wiring from the actuator to the appropriate control source. This is often wired from the thermostat or a central wiring centre. This connection powers the unit.
