4 Wire 230v Underfloor Heating Actuator
  • Description

    This precision thermal actuator for underfloor heating systems monitors and regulates room temperatures by auto-opening/closing port valves based on thermostat inputs, providing precise underfloor heating temperature regulation.

    It integrates seamlessly with underfloor heating manifolds, thermostatic valve bodies, and three-way valves in water-based radiant floor heating setups, ensuring optimal hydronic flow and energy-efficient performance in zoned home heating systems.

    Key Features and Benefits

    • Normally Closed Underfloor Heating Thermal Actuator for Secure Control: Offers normally closed operation for energy-efficient control in underfloor heating systems with manifold valves, preventing flow until thermostat activation to enhance radiant floor heating safety in multi-zone installations.
    • M30 Thread Compatibility for Underfloor Heating Manifolds and Valves: Universal M30 x 1.5 thread fits most modern underfloor heating manifolds, thermostatic valve bodies, and three-way valves—perfect for retrofits in residential or commercial radiant heating applications.
    • 3mm Stroke Length Thermal Actuator for Precise Valve Positioning: Provides 3mm stroke for accurate valve positioning and responsive temperature regulation in underfloor heating circuits, boosting comfort in electric or water underfloor heating setups.
    • Low 2W Power Consumption Underfloor Heating Actuator for Energy Savings: Efficient 2W draw cuts costs, ideal for 24V low-voltage underfloor heating systems in eco-friendly residential and commercial radiant floor heating buildings.
    • 4-Wire Configuration Thermal Actuator Wiring for Easy Integration: Standard 4-wire setup simplifies electrical connections for thermostat integration in multi-zone underfloor heating setups, avoiding wiring issues in control panels or manifold replacements.
    • Tool-Free Installation Underfloor Heating Actuator for Quick Setup: No-tools mounting speeds setup on M30-threaded underfloor heating manifolds, minimizing downtime for DIY or pro radiant heating upgrades.
    • Silent Operation Compact Thermal Actuator Design for Discreet Use: Whisper-quiet and compact for discreet fit in underfloor heating control panels, ensuring silent operation in homes or offices.
    • CE Marked Reliable Underfloor Heating Thermal Actuator for Longevity: CE-certified for safety and durability, delivering interruption-free service in radiant underfloor heating to extend system life and save energy.

    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.
