What it is

The Altecnic Thermoelectric Actuator 230V is a mains-powered thermal actuator used to open and close the valves on Altecnic underfloor heating systems. It operates by heating a thermoelectric element inside the head, which moves the valve stem to regulate flow through the circuit. This version is supplied as a 230V unit for systems wired to mains voltage.

Signs this part needs replacing

  • A zone or circuit fails to reach temperature even though the manifold controls are calling for heat
  • The actuator head runs warm but the valve stem does not move
  • A circuit overheats because the valve stays open when it should close
  • Visible cracking, deformation or a burnt smell at the actuator body
  • Control voltage is present at the actuator but there is no response at the valve

Before you order

  • Confirm the existing actuator is a 230V unit and that the supply wiring to it matches
  • Check that the actuator is being used on an Altecnic underfloor heating system
  • Note the product code 656102 so it can be cross-checked against the part being replaced
  • Isolate the mains supply before removing the existing actuator head
