TIO 24V Normally Closed Thermal Actuator for UFH Manifolds - 2 Wire, IP54

The TIO 24V Normally Closed Thermal Actuator for UFH Manifolds is an easy-install electrothermal actuator designed for underfloor heating (UFH) manifolds and valves, providing reliable control in domestic hot water and heating systems with a quick reaction wax capsule and IP54 protection.

Product Description

The TIOACT0002 is a 24V normally closed (NC) thermal actuator suitable for controlling valves in underfloor heating manifolds, radiators, and other heating systems. It uses an electrothermic wax element for precise and fast response, opening the valve when powered. The actuator features a 2-wire connection, M30 x 1.5 thread, and comes with a retaining clip for normally open configuration if needed. It is designed for easy installation and maintenance, with high IP54 protection against dust and water.

Key Features

• Normally closed (NC): Valve opens when powered; can be configured as normally open with retaining clip.
• Quick reaction time: Electrothermic wax capsule for faster response.
• 2-wire connection: Simple live and neutral wiring with extended 780mm cable.
• IP54 rated: Protection against dust and water splashes.
• M30 x 1.5 thread: Standard connection for most manifolds and valves.
• Power supply: 24V AC or DC.
• Low power consumption: ≤3W (in rush current requires time delay fuses).
• Adaptive stroke length: 3.5mm.
• Pop up indicator: 'Open/Closed' status indicator.
• Silent and maintenance-free: Fire retardant plastic shell.
