Thermal Actuator 920071PL
The 920071PL Smart Thermal Actuator is an app-controlled electrothermal valve actuator built for floor heating systems, combining reliable thermal actuation with WiFi and ZigBee connectivity through the Tuya smart platform. Manufactured by Legom with a durable glass-fiber reinforced PA66+30%GF housing, it converts an AC 220V supply into smooth, silent valve movement, delivering a load of 100±10N and a stroke of ≥4mm while drawing only 2W of power.
Unlike a conventional thermostat-wired actuator, the 920071PL can be operated from a smartphone, allowing remote control and scheduling of each heating zone through the Tuya app. Built to the EN 60730 standard for automatic electrical controls, it fits standard manifold valves through an M30x1.5mm connection, carries an IP54 protection rating, and responds within 3 to 5 minutes, delivering the wear-free control that thermal actuators are valued for together with modern smart-home convenience.
Key Benefits
- Smart app control via Tuya – Connects through WiFi or ZigBee to the Tuya smart platform, enabling remote control and scheduling of each heating zone from a smartphone
- Dual connectivity options – Supports WiFi for direct app control and ZigBee for low-power mesh integration within a Tuya smart-home network
- Purpose-built for floor heating systems – Designed to actuate manifold valves in hydronic underfloor heating for room-by-room temperature control
- AC 220V, low 2W consumption – Runs on standard mains supply with minimal holding load, keeping running costs low across multi-zone manifolds
- Silent, wear-free actuation – The thermal operating principle uses no motor or solenoid, giving quiet operation and long service life with no mechanical switching wear
- IP54 protection grade – Dust and splash protection makes the unit suitable for the typical manifold cabinet and utility-room environment
- EN 60730 compliant – Meets the international standard for automatic electrical controls for household and similar use
- Standard M30x1.5mm connection – Fits the majority of underfloor heating manifold valves and common zone valve bodies without custom hardware
- PA66+30%GF housing – Glass-fiber reinforced nylon resists heat and mechanical stress for reliable performance in warm manifold environments
- OEM and ODM customization available – Connectivity, adapter thread, cable length, and housing can be adapted to specific product and market requirements

Application & Use Cases
- Smart underfloor heating manifolds – The primary application, where each actuator opens and closes a manifold valve under app control, enabling remote and scheduled room-by-room temperature management
- Tuya smart-home systems – Integrates into a Tuya-based smart home so heating zones can be controlled alongside other connected devices from one app
- Zone valve control – Drives manifold-mounted zone valves in multi-zone hydronic systems, switching flow to individual circuits on demand
- Remote and scheduled heating – Lets users adjust or program heating from anywhere, useful for holiday homes, rentals, and energy-conscious households
- Retrofit smart upgrades – Adds app control to existing manifold systems that use a standard M30x1.5 valve interface
Installation Notes
- Mount the actuator on a compatible valve using the M30x1.5mm connection. Confirm the valve thread before installation
- Connect the unit to a stable AC 220V supply in accordance with EN 60730 and local electrical regulations
- Pair the actuator with the Tuya app during commissioning. WiFi units connect directly to the home router, while ZigBee units require a compatible ZigBee gateway
- Ensure the installation location has adequate wireless signal from the router or ZigBee gateway for reliable remote control
- Allow for the 3 to 5 minute response time. Thermal actuators are slow-acting by design and do not respond instantly like solenoid valves
- Observe the IP54 rating. The actuator is protected against dust and splashing water but must not be submerged or installed in fully exposed outdoor locations
- Keep the unit within the -5°C to 60°C operating temperature range and install it in the recommended upright orientation on the valve
- For OEM integration, confirm two key parameters in writing before finalizing the order: connectivity type and adapter thread
Frequently Asked Questions
How is the 920071PL controlled?
The 920071PL connects to the Tuya smart platform through WiFi or ZigBee, so it is controlled from the Tuya app on a smartphone. Users can switch zones on and off, set schedules, and adjust heating remotely, rather than relying only on a hardwired thermostat.
What is the difference between the WiFi and ZigBee versions?
The WiFi version connects directly to the home router and needs no additional hardware, which is convenient for a small number of actuators. The ZigBee version uses a low-power mesh network and requires a compatible ZigBee gateway, which is more efficient and stable when many devices are connected across a larger installation.
Why does the actuator take 3 to 5 minutes to respond?
Thermal actuators operate by heating an internal expansion element rather than using a motor or solenoid, so movement is gradual by design. This slow, silent, wear-free actuation is ideal for underfloor heating, where rapid switching is unnecessary and smooth flow control improves comfort and valve life.
Which valves is the 920071PL compatible with?
The actuator connects through an M30x1.5mm interface, which fits the majority of underfloor heating manifold valves and common zone valve bodies. Confirm that your valve uses the M30x1.5 thread before ordering.
Where can the 920071PL be installed given its IP54 rating?
The IP54 rating means the actuator is protected against dust and against splashing water from any direction. It is suitable for typical indoor manifold cabinets and utility spaces, but it should not be submerged, exposed to pressure jets, or installed in fully exposed outdoor conditions.
Can the 920071PL be customized for OEM projects?
Yes. Legom offers full OEM and ODM services. Connectivity type, adapter thread, cable length, and housing details can be adapted to your product requirements. Written confirmation of two key parameters is required before a customization project begins: connectivity type and adapter thread. Contact us via WhatsApp or email to start the process.
