Thermal Actuator 920075PL
The 920075PL Smart Thermal Actuator is an app-controlled electrothermal valve actuator for floor heating systems, pairing dependable thermal actuation with WiFi and ZigBee connectivity through the Tuya smart platform. Available in a choice of eight colors and built with a heat-resistant PA66+30%GF housing, it runs on an AC 220V supply, moves the valve with a 4mm stroke, and consumes only 2W.
What sets the 920075PL apart is the combination of smartphone control and design flexibility. Each heating zone can be operated and scheduled remotely through the Tuya app, while the eight-color range lets installers match the actuator to the interior or color-code circuits on a manifold. It connects to manifold valves via an M30x1.5mm thread, carries an IP41 rating, complies with the EN 60730 standard, and responds within 3 to 5 minutes with the quiet, wear-free movement typical of thermal actuators.
Key Benefits
- Smart app control via Tuya – Connects over WiFi or ZigBee to the Tuya platform, so each zone can be controlled and scheduled from a smartphone, anywhere
- Eight color options – A range of eight finishes lets the actuator blend with the interior or visually code circuits across a manifold
- WiFi and ZigBee connectivity – WiFi for direct app control, ZigBee for low-power mesh integration within a Tuya smart-home network
- Made for floor heating – Designed to actuate manifold valves in hydronic underfloor heating for room-by-room control
- AC 220V, 2W – Runs on standard mains with a low holding load across multi-zone manifolds
- Quiet, wear-free operation – Thermal actuation uses no motor or solenoid, giving silent movement and long service life
- IP41 protection grade – Suited to dry, protected indoor manifold and cabinet locations
- EN 60730 compliant – Meets the international standard for automatic electrical controls for household and similar use
- M30x1.5mm connection – Fits the majority of underfloor heating manifold valves and common zone valve bodies
- OEM and ODM customization available – Color, connectivity, adapter thread, and housing can be adapted to specific requirements

Application & Use Cases
- Smart underfloor heating manifolds – Each actuator opens and closes a manifold valve under app control, enabling remote and scheduled temperature management per room
- Tuya smart-home systems – Fits into a Tuya-based smart home so heating zones sit alongside other connected devices in one app
- Design-conscious installations – The eight-color range suits visible manifolds or projects where appearance matters
- Color-coded manifolds – Different colors can mark different zones or floors for easier identification during service
- Retrofit smart upgrades – Adds app control to existing manifolds that use a standard M30x1.5 valve interface
Installation Notes
- Fit the actuator to a compatible valve using the M30x1.5mm connection, confirming the valve thread first
- Connect to a stable AC 220V supply following EN 60730 and local electrical regulations
- Pair the unit with the Tuya app during commissioning. WiFi units join the home router directly, while ZigBee units need a compatible ZigBee gateway
- Check that the location has adequate wireless signal from the router or gateway for dependable remote control
- Because the IP41 rating protects only against vertically dripping water, install the actuator in a dry, sheltered indoor position away from spray or outdoor exposure
- Allow the 3 to 5 minute response time. Thermal actuators move gradually rather than instantly
- Keep the unit within the -5°C to 60°C operating range and mount it upright on the valve as recommended
- For OEM orders, confirm two key parameters in writing before finalizing: connectivity type and adapter thread
Frequently Asked Questions
How is the 920075PL controlled?
It connects to the Tuya smart platform over WiFi or ZigBee and is operated from the Tuya app on a smartphone. Users can switch zones on and off, program schedules, and adjust heating remotely, rather than relying only on a hardwired thermostat.
How many colors are available, and why does it matter?
The 920075PL is offered in eight colors. This is useful for visible manifold installations where appearance matters, and it also allows different colors to mark different zones or floors, making a multi-actuator manifold easier to identify during setup and service.
What is the difference between the WiFi and ZigBee versions?
The WiFi version connects straight to the home router without extra hardware, which is convenient for a few actuators. The ZigBee version uses a low-power mesh and needs a compatible gateway, which is more stable and efficient when many devices are connected across a larger installation.
Where can the 920075PL be installed given its IP41 rating?
The IP41 rating means protection against solid objects larger than 1mm and against vertically dripping water. Install it in a dry, protected indoor location such as a manifold cabinet or utility space, and avoid places exposed to spray, jets, or outdoor weather.
Which valves is the 920075PL compatible with?
The actuator connects through an M30x1.5mm interface, which fits most underfloor heating manifold valves and common zone valve bodies. Confirm that your valve uses the M30x1.5 thread before ordering.
Can the 920075PL be customized for OEM projects?
Yes. Legom offers full OEM and ODM services. Color, connectivity type, adapter thread, and housing details can be adapted to your product requirements. Written confirmation of two key parameters is required before a project begins: connectivity type and adapter thread. Contact us via WhatsApp or email to start the process.
