Water-based comfort, room by room. For hydronic floor heating projects using compatible actuators and control wiring.

Black finish shown. Four housing colors available.
Select the hydronic output configuration for the room’s actuator or wiring center. Match the control voltage and wiring diagram before installation; this thermostat does not directly control the water temperature in a manifold.
Please provide: actuator voltage, normally open / normally closed operation, wiring center and zone arrangement, destination country, preferred ecosystem and quantity.
The Matter edition is being introduced for temperature and operating-mode control through compatible Matter platforms. Request the current sample compatibility list for Apple Home, Google Home, Amazon Alexa and Samsung SmartThings.
Use the controls exposed by your chosen platform. Available modes and screen layouts depend on the firmware and platform.
Matter supports sharing a device with additional compatible ecosystems through their pairing flows. Required controllers and network setup depend on the ecosystem.
A clear temperature display and touch keys keep everyday adjustment within reach. Confirm schedules, sensor settings and advanced functions on the selected sample.
Matter edition launch: final firmware features, ecosystem compatibility, certification status and availability are confirmed with the sample specification. Module demonstrations are not a certification claim for the finished thermostat.

Yes. Black, white, silver and gold are housing choices. Within the same heating configuration, the color does not change the hardware or software.
Do not assume that every local thermostat function appears in every Matter app. Temperature and mode are the current integration focus; confirm scheduling, floor limits and advanced settings on the sample.
Verify the supply, output type, load and sensor against the exact wiring diagram supplied for your configuration. Installation should be carried out by a qualified professional.
