SKU: TR-2046

The thermal actuator monitors the operation of your underfloor heating system by automatically opening and closing the port valve to regulate the room temperature set at the thermostat. It is suitable for mounting on underfloor heating manifolds, thermostatic valve bodies and three-way valves.

The actuator is designed to fit our range of manifolds but can also be mounted on most modern underfloor heating manifolds with an M30 thread.

The robust housing and internal structure ensures longevity and reliable performance for many years without the worry of deterioration or interruption to the operation of your underfloor heating system.

Available in standard 230v and 24v for low voltage systems.

Features:

  • Normally closed
  • M30 thread
  • 3mm stroke length
  • 2w power consumption
  • 2 wires as standard
  • No tools required for fitting
  • Silent operation
  • Compact design
  • CE marked

Mounting onto the manifold

  1. Remove the isolation cap on the return manifold
  2. Position the actuator onto the port value
  3. Tighten the ring nut by hand- do NOT use a spanner or similar tool.
  4. Connect the electrical wiring to complete.

 

 

Function of Normally Closed Version (NC)

  • When applying the operating voltage, the expansion system of the actuator will be heated. After passing the dead time a uniform procedure will follow.
  • When the voltage supply is cut off, the actuator will automatically close after passing the dead time due to calling of the expansion system.

Note: in case of any functional testing, be aware of the dead time behaviour and take this into consideration. The opening and closing ties will depend upon the ambient temperature.
