Overview
The SunAura Touch WiFi Thermostat is an all-black glass front-face smart controller built for underfloor heating and radiator systems across electric, water and wall-hung boiler installations. A single sheet of black glass covers the entire 86 × 86 mm faceplate; beneath it, a backlit LCD and five invisible touch keys — power, mode, timer, up and down — replace mechanical buttons, giving the unit a clean, frameless look that suits modern interiors in living rooms, bedrooms, bathrooms, offices, hotels and light commercial spaces.
Beyond the appearance, the thermostat is designed for everyday temperature control. The LCD shows the measured room temperature, the set target, the day of week, the clock and the heating output status at a glance, so household members can read the current state without opening a phone. When joined to the home WiFi network and a Tuya-compatible smart app, the same unit becomes a remote controller: users can adjust the temperature, run a weekly heating schedule, switch the heating on before they arrive home and lock the keys, all from a smartphone from anywhere. It also works with Amazon Alexa and Google Assistant for hands-free voice control.
Two electrical versions cover the main heating system types. The 16 A electric-heating version switches resistive electric heating cables, heating films and underfloor heating mats directly, while the 3 A version with dry-contact output is used to switch water-heating manifolds, circulation pumps and wall-hung boilers. Both share the same glass faceplate, display and smartphone app, so installers and distributors can keep one product family for mixed residential and commercial projects.
The SunAura Touch WiFi Thermostat is manufactured by SunAura Thermal from our Qingdao factory, operating with ISO-style quality management and in-line testing on every production batch, with more than 17 years of OEM/ODM experience supplying heating controls to customers in 50+ countries. Every unit is tested before shipment and carries CE compliance, with a 2-year factory warranty and direct after-sales support.
Key Features
- All-black glass touch panel — a seamless black glass face with five capacitive touch keys; no protruding buttons to clean, scratch or break.
- Backlit LCD at a glance — large room-temperature numerals, set temperature, clock, weekday and heating status stay readable day and night.
- WiFi smartphone control — full remote operation through a Tuya-compatible app for iOS and Android, including away-from-home adjustments and pre-heating.
- Weekly programming — six weekday periods plus two weekend periods per week, with 5+2, 6+1 and 7-day schemes selectable in the app; each period has its own target temperature.
- Voice control ready — works with Amazon Alexa and Google Assistant, so the temperature can be changed by voice in supported households.
- Child lock — an on-screen lock icon and an app-side switch prevent children or guests from accidentally changing the programme.
- Power-off memory — the set temperature, schedule and mode are retained through power cuts, so no re-programming is needed after an outage.
- Two load versions for every heating type — 16 A direct-switching output for electric heating; 3 A dry-contact output for water heating manifolds, pumps and wall-hung boilers.
- External sensor terminals — terminals 5 and 6 accept an external NTC probe for floor-sensing, pipe-sensing or average-room sensing applications.
- Slim, safe and standard-sized — 86 × 86 mm square faceplate, about 14 mm deep, fitting the standard 86 mm European wall box; flame-retardant PC housing with an IP20 backplate.
Display & Icon Guide
The LCD communicates the full heating state in a single glance. The weekday indicator at the top left shows the current day (MON–SUN); the time display shows the clock in 24-hour format. The house outline labels the large numerals as the measured room temperature, while the smaller numerals marked SET are the programmed target temperature, so the two readings are never confused. The heating waves icon lights whenever the output is energised, the hand/lock icon confirms child-lock status, and the time-slot indicator identifies which programmed period is active.
Below the glass, five invisible touch icons run in a row: power (standby / wake), mode (manual / programme / holiday), timer (weekly schedule entry), up and down (temperature adjustment). A short tap changes the set temperature; a long press enters the programming menu. The screen backlight wakes on touch and dims automatically after a few seconds to keep the room quiet at night.
The weekly programme is built around a typical home routine: six weekday periods (for example morning wake-up, day setback, lunch, afternoon setback, evening comfort and overnight setback) and two weekend periods for a later start and an earlier wind-down. The 5+2, 6+1 and 7-day schemes can be switched in the app, and every period temperature is freely adjustable — typically 5–15 °C setback when the house is empty and 20–22 °C comfort when occupied.

Applications
The Touch WiFi Thermostat is a universal controller for the three most common hydronic and electric heating schemes in residential and light commercial buildings:
- Electric underfloor heating — heating cables, heating mats, graphene/PET heating film and infrared panels switched directly by the 16 A output.
- Water underfloor heating — the 3 A dry-contact output switches the zone valve or circulation pump of a water manifold.
- Wall-hung boilers and radiators — dry-contact on/off control of a wall-hung boiler (heat demand), suitable for radiator-led systems and hybrid installations.
- Apartments, villas and hotels — one shared app account can manage several thermostats, one per room or zone, with independent schedules.
- Holiday homes and offices — remote monitoring, frost protection and setback programming reduce energy use while the space is unoccupied.
Installation
- Mark and drill — install the expansion screw cartridges on the wall at a spacing of 60 mm (drill Ø 3–3.5 mm), matching the standard 86 mm wall box.
- Open and wire — use a screwdriver to separate the front glass cover from the backplate, thread the mains wires through into the terminal block according to the wiring diagram, leaving about 20 cm of wire for easy connection.
- Fix and connect — secure the backplate to the wall with the screws; connect L / N for mains and N1 / L1 to the heating load, plus external probe terminals 5 / 6 when a floor or pipe sensor is used; tuck the wires neatly into the cavity.
- Close and pair — align the glass cover and buckle it into place at a 30° angle, power on, then pair the thermostat with the Tuya-compatible app on a 2.4 GHz WiFi network.
Always confirm the version before wiring: the 16 A electric-heating version carries the heating current directly, while the 3 A version is a dry (volt-free) contact intended for boilers, pumps and zone valves — connecting a water system to the 16 A version or a high-current electric load to the 3 A contact would damage the unit. Installation should be carried out by a qualified electrician, and the connected load must not exceed the rated output. A dedicated wiring diagram ships with every order, and our engineers are available by WhatsApp for remote commissioning support.

FAQ
1. How do I operate the touch screen?
The glass panel is fully capacitive — there are no physical buttons. Tap up or down to change the set temperature, tap mode to switch between manual and programme mode, and tap timer to enter the weekly schedule. The screen wakes on touch and dims automatically; a long press on the lock icon, or the child-lock switch in the app, disables the keys.
2. Which version do I need — 16 A or 3 A?
Choose the 16 A version when the thermostat must switch electric heating directly — heating cables, mats or films up to the rated load. Choose the 3 A dry-contact version for water underfloor heating (manifold / pump) and wall-hung boilers, where the thermostat only sends a heat-demand signal and never carries the heating current. Tell us your heating type when ordering and we will confirm the correct version.
3. How do I pair the thermostat with the smartphone app?
Install the Tuya-compatible smart app on an iOS or Android phone, connect the phone to a 2.4 GHz WiFi network, add the device in the app and follow the on-screen pairing steps (typically holding the mode key until the WiFi indicator flashes). Once paired, you can adjust temperature, edit the weekly programme and check heating status remotely, and share the device with family members.
4. Do my settings survive a power cut?
Yes. The thermostat keeps the set temperature, weekly programme, mode and WiFi pairing in non-volatile memory. When power returns, it resumes the last programme automatically — there is no need to re-pair or re-programme after an outage.
5. Can I use an external sensor?
Yes. Terminals 5 and 6 on the backplate accept an external NTC probe. In electric underfloor heating this probe is usually fitted beneath the floor to monitor surface temperature and protect the floor build-up; in water systems it can be used to average room temperature or sense pipe return temperature. The sensor type (internal room sensor or external probe) is selected in the device menu or app.
6. How does the weekly programming work?
Each week is divided into up to six weekday periods and two weekend periods, and you can switch the schedule between 5+2, 6+1 and 7-day schemes. Every period carries its own start time and target temperature — for example, 21 °C in the morning and evening, 15 °C while the house is empty. Programming is easiest in the phone app and is then stored permanently on the device.
7. What is the child lock and how do I turn it on?
Child lock freezes the touch keys so that accidental touches by children or guests do not change the heating programme. Activate it from the app, or from the device menu; a small hand/lock icon appears on the LCD while it is active. Deactivate it the same way when you need to adjust settings.
8. What is the warranty and after-sales support?
Every SunAura Touch WiFi Thermostat carries a 2-year warranty and direct after-sales support from SunAura Thermal — spare parts, configuration help and commissioning guidance by WhatsApp. OEM and distributor customers can request extended terms, private-labelling and project-specific documentation for tenders.

FAQ (continued)
9. Can I order the Touch WiFi Thermostat as a wholesale or OEM product?
Yes. SunAura offers wholesale price breaks, EXW or FOB quotations, CE certification documents and private-labelling on the fascia and packaging for distributors and OEM partners. Tell us whether you need the 16 A electric version or the 3 A dry-contact version, and we will quote MOQ, lead time and sample options the same day.
10. Is the black glass front suitable for bathrooms and humid rooms?
The Touch thermostat is intended for indoor wall mounting on the standard 86 mm box in living rooms, bedrooms, offices and hotels, with an IP20 backplate. In wet rooms such as showers, installers usually mount the thermostat outside the wet zone and use the external NTC probe on terminals 5 and 6 to sense the floor — confirm the layout with your electrician before wiring.
11. Can I mix 16 A and 3 A units on the same app account?
Yes. Both versions use the same Tuya-compatible app, so one household or project account can manage several thermostats at once — for example a 16 A unit on an electric underfloor circuit and a 3 A unit on a wall-hung boiler zone — each with its own weekly schedule and target temperature.
What does the black glass touch thermostat look like?
It is a full-black glass-front touch panel with minimal bezel, flush-mounted on a standard 86 mm wall box. The black glass and edge-to-edge digits suit modern interiors and show only what you need.
Which systems does it control?
It supports electric underfloor heating (16 A resistive: film, mat, cable), radiator valves and gas boiler on/off (3 A dry contact). Select the load type in the installer menu during first power-up.
Does it include a floor sensor?
Yes. An external NTC floor probe on a 3 m lead is included. Connect it to enable floor-temperature limiting (protecting wooden floors) or to run the unit in pure floor-sensor control mode.
Is app and voice control supported?
Yes. It joins 2.4 GHz WiFi and pairs with the Tuya Smart / Smart Life app for remote setpoint, 7-day scheduling and away mode. It also works with Alexa and Google Home for voice control.
Can I order it with my own brand?
Yes. SunAura supplies this black-glass WiFi touch thermostat as an OEM/ODM product: custom logo on the glass, private-label packaging, multilingual firmware and volume production. Contact us for MOQ.
