New Arrival: HY213RF WiFi + RF Wireless Thermostat with Receiver — Wire-Free Comfort for Hydronic Heating
Leave a message
Why the HY213RF?
Hydronic central heating is efficient, quiet and comfortable - but controlling it has always meant the same compromise: a thermostat that has to be wired back to the boiler, installed where the cable allows, not where the room actually needs it.
The newly launched HY213RF removes that compromise entirely. It is a Wireless Room Unit + Receiver set: the thermostat goes wherever the room needs it - on the wall or free-standing - while a compact receiver handles the switching at the boiler or zone valve. No wired controller needed.
Two Devices, Zero Wiring Between Them
The HY213RF system is built on a simple, reliable split architecture:
Room unit - battery powered, installs anywhere with no wiring at all. Move it when you want to; no electrician required.
Receiver - wired directly to the boiler or zone valve, and powered from the mains (110–230 V).
RF 2-way communication between them keeps the link reliable: the room unit sends commands, the receiver confirms its status back.
The result is a heating system that responds to the actual room - not to where the cable happened to reach.
Control Your Heating from Your Phone
The HY213RF works with the Tuya Smart Life App, so your heating is never out of reach:
See the room temperature at a glance, wherever you are.
Set your target temperature with the app's simple + / − control.
Switch to heating mode remotely - warm the house before you arrive home.
Build a daily schedule - set different temperatures for time slots across the day (e.g. 06:00 / 08:00 / 18:00 / 22:00) and let the system run itself.
Clear Display, Simple Touch
On the wall, the HY213RF stays effortless to use:
Dot-matrix display showing the temperature clearly - 26.5 in a bold, readable format.
Status icons at a glance: heating (sun), manual control, home status and battery level.
Only 4 touch keys - menu, down, up and confirm. No instruction manual required.
Night mode for undisturbed sleep, so the display and operation suit bedrooms as well as living rooms.
The Receiver Built for Heating Systems
The receiver is the workhorse of the set, engineered for real hydronic installations:
110–230 V mains power supply - suited to a wide range of markets.
20 A maximum relay load - enough headroom for boilers and zone valves.
Wide wiring range: 14–18 AWG - flexible on site, easy for installers to terminate.
On-board indicators for power, load, signal and WiFi, so status and troubleshooting are immediate.
Manual push button with ON/OFF - local override is always available.
Simple Installation - Three Steps
Place the battery room unit - mount it anywhere, no wiring required.
Wire the receiver to the boiler / zone valve (110–230 V | 20 A).
Pair via the app - set it up through Tuya Smart Life and you are running.
