Thermostats & Controls

Intelligent Temperature Control for Every Heating System

A heating system is only as good as its controller. SunAura’s thermostat range covers every installation scenario — from a simple wired thermostat for a bathroom mat to a WiFi colour-LCD controller that programmes the whole home from your phone. All models are built in our Qingdao factory, batch-tested, CE and RoHS compliant, and backed by direct factory support.

This category groups the full control line: WiFi smart thermostats (K1M, K2M, K9, K5, KC02, K6H, touch, knob, piano-key, SDM5, SDM6), the RF wireless boiler thermostat for wall-hung boiler systems, the K1 wired thermostat for simple reliable control, and the indoor thermometer & hygrometer companion. The Smart Thermostats series page explains the shared features and certification of the whole range.

Choosing the Right Thermostat

WiFi + app control

If you want remote control, weekly schedules and pre-heating from anywhere, choose a WiFi model — K1M, K2M, K9, K5, KC02, K6H, SDM5, SDM6, touch, knob or piano-key. They pair with the Tuya app (iOS/Android), support voice control through Tuya-compatible assistants, and most include floor-sensor options, child lock and holiday mode.

RF wireless for boilers

The RF wireless boiler thermostat (WITH3 series) suits wall-hung boilers, gas heaters and hydronic systems where a wired connection is impractical — the wireless receiver switches the boiler while the remote panel controls temperature from anywhere in the room.

Simple wired control

The K1 wired thermostat is the dependable choice for film, mat and cable loads up to 16 A/25 A with ±1 °C accuracy, three working modes and a white backlight LCD — no WiFi needed.

Smart Features Across the Range

• Weekly time-slot programming — up to six periods per day with independent temperatures for weekdays and rest days.
• Child lock — prevents accidental operation by children and guests.
• Energy-saving mode — reduced set temperature outside active hours cuts consumption.
• Display recalibration — ±1 °C accuracy with a simple calibration offset.
• Power-off memory — settings survive power cuts with no re-programming.
• Antifreeze protection — keeps pipes and holiday homes above freezing.

Compatibility

Every thermostat in this category is load-matched to our heating film, mats, cables, 0.5 mm aluminium-film renovation mats and DIY installation kits. Buy the element and thermostat together and we pre-set the temperature range and sensor options to your floor build-up — one package, one warranty, one engineering contact.

Quality, Certification & Support

Thermostats are manufactured under ISO-style quality management with batch testing, carry CE and RoHS marking, and SGS certification documents are available on request. Every unit includes a 2-year warranty and direct after-sales support — spare parts, configuration help and commissioning guidance by WhatsApp.

FAQ

1. Which thermostat do I need for heating film?

Any of our WiFi thermostats with a floor-sensor option (e.g. K1M, K2M, K9) is ideal for film floors. Confirm your connected load and sensor requirement when ordering.

2. Do the WiFi thermostats work without internet?

Yes — all models operate fully as standalone thermostats with local buttons. WiFi only adds remote control and scheduling through the app.

3. Can one thermostat control several rooms?

Each thermostat controls one heating zone up to its rated load. For multi-room homes we recommend one thermostat per zone, or a contactor-controlled installation for very large loads.

4. What voltage do the thermostats support?

Models accept 90–240 VAC, 50/60 Hz, with load ratings of 3 A (dry contact), 16 A and 25 A — choose the version that matches your heating load.

5. Do you offer OEM/private-label thermostats?

Yes — we supply distributors and OEM customers with private-labelled branding, custom default programmes and packaging design across the whole thermostat range.

Smart Thermostats for Electric Underfloor Heating and Wall-Hung Boilers

Specifying the right controller is where most heating projects are won or lost. For electric underfloor heating — film, mats, cables and aluminium-film renovation mats — you need a thermostat with a floor-sensor input and a load rating matched to your connected watts. Our WiFi range (K1M, K2M, K9, K5, KC02, K6H, touch, knob, piano-key, SDM5 and SDM6) covers everything from a single bathroom mat up to large multi-room zones, and each model pairs with the same app experience: weekly schedules, remote pre-heating, holiday mode and energy-saving setback. For hydronic systems and wall-hung boilers, the RF wireless thermostat removes the need for new wiring between the room and the boiler, while the simple wired K1 remains the dependable choice where app control is not required.

Across the range, weekly time-slot programming lets heating follow real life — warming the home before you arrive, setback while you are out, and antifreeze protection for holiday houses and empty rentals. Pairing a controller with a room sensor or the indoor thermometer-hygrometer also adds humidity awareness in bathrooms, basements and grow rooms. For very large loads we recommend one thermostat per zone with a contactor arrangement, which our engineers can size with you. Compare the K1M WiFi thermostat, the RF wireless boiler thermostat, and the K1 wired thermostat for load rating, display style and control features before you order.

How to Buy: Wholesale, Bulk & OEM

SunAura supplies thermostats factory-direct to heating distributors, installers and e-commerce sellers. Wholesale price enquiries are welcomed for both single-model container loads and mixed ranges, with bulk discounts tied to order volume and annual turnover. MOQ depends on model and packaging — standard colour-LCD, knob and piano-key models are easier to stock in volume, while custom private-labelling carries its own MOQ subject to quotation. Typical lead time is 20–35 days for production orders after sample approval. Free samples of most models are available for qualified trade and distribution partners so you can bench-test wiring, app pairing and floor-sensor behaviour before making a volume commitment.

Our OEM/ODM and private-label programme covers custom boot-up logos, default weekly programmes, relay ratings, button language and retail packaging across the whole WiFi, RF and wired line. We export on EXW and FOB Qingdao terms and provide CE, RoHS and SGS certification documents on request. Contractors fitting whole housing projects can bundle thermostats with our heating elements into one shipment, one quotation and one warranty. Spare parts, configuration help and commissioning guidance are included with every order, and our support team assists installers by WhatsApp during first-time setup. Whether you stock one colour-LCD model for everyday jobs or carry the full touch, knob, piano-key and SDM line for premium and retrofit projects, the same factory terms and documentation apply across the range.

Beyond the controller itself, we supply the matching floor sensors, air sensors, contactors for large loads and the indoor thermometer-hygrometer that sits alongside the thermostat in living rooms, nurseries and grow rooms. This means a distributor can stock one controller range and still meet nearly every retrofit, new-build and boiler-replacement enquiry without sourcing from multiple factories.

Send your model list and target markets to our sales team, or chat with us on WhatsApp for same-day feedback. More fit-out ideas are on the applications page, and common wiring and pairing questions are answered on the FAQ page.

Every unit is batch-tested before dispatch and shipped with its compliance documents and quick-start guide, so your stock arrives shelf-ready. If you are still deciding between a WiFi, RF or wired model for a specific project, send us your load and wiring details and we will recommend the right controller within one working day — no obligation, just factory-direct advice.
