Where to find us

Finding booth 17.2M21 at the Canton Fair

The Canton Fair Complex is one of the largest exhibition venues in the world. Here is the fastest route to our stand:

• Go to Area D and enter Hall 17.2.

• Walk along Row M to position 21.

• You have arrived at 17.2M21.

Reading the booth number: 17.2M21 breaks down as hall 17.2, row M, stand 21. This makes wayfinding straightforward once you are inside Hall 17.2.

PC471 Series: 3-phase smart energy meters with Ethernet + WiFi

The PC471 Series is our flagship DIN-rail energy metering platform for residential, commercial and industrial energy management. It is built around four advantages that matter most to system integrators and OEM partners.

Ethernet + WiFi dual connectivity

Wired and wireless on the same device. Use Ethernet for a stable, low-latency backbone in commercial and industrial panels, with WiFi as a redundant path or for fast commissioning on site.

Built-in relay with dry-contact output

The integrated dry-contact relay enables direct load switching and demand-side control without adding an external relay module — fewer components, less wiring and a lower bill of materials.

Compact DIN-rail form factor

A slim, standard DIN-rail housing saves valuable panel space and keeps installation quick for electrical contractors.

CT-clamp measurement with bidirectional metering

Split-core CT clamps deliver accurate three-phase measurement and support bidirectional energy flow — essential for solar PV self-consumption monitoring and EV charging applications.

Two firmware editions: Open Protocol and Tuya

Choose the edition that matches your platform strategy:

• Open Protocol edition — RS485 with Modbus RTU and Modbus TCP, plus MQTT and HTTP, for direct integration with your own cloud, EMS or BMS.

• Tuya edition — pre-integrated with the Tuya ecosystem over WiFi and Ethernet for the fastest possible time to market in connected-home and light-commercial projects.

Energy management models compared

Connectivity across the range: WiFi · Ethernet · 4G · ZigBee · LoRa · RS-485 · Modbus · MQTT · Tuya.

Typical applications: residential and commercial energy management, solar PV monitoring, smart building, EV charging, EMS and BMS projects.

North America 24Vac HVAC thermostat series

Our North America thermostat platform is engineered specifically for 24Vac residential and light-commercial HVAC systems, covering conventional, multi-stage heat pump and dual-fuel configurations.

Broadest system compatibility

One platform covers conventional systems, multi-stage heat pumps and dual-fuel setups — reducing the number of SKUs distributors and contractors need to stock.

Large colour touchscreen with an intuitive UI

The PCT533 features a 4.3-inch full-colour touchscreen with a clear, glanceable interface for temperature, operating mode and humidity.

Occupancy sensing and humidity control

Built-in occupancy detection automatically reduces heating and cooling when a space is empty, while humidity control improves comfort and helps prevent condensation and mould.

Multi-room remote sensors

The PCT5231 supports up to 10 remote room sensors for balanced whole-home temperature control and accurate multi-zone comfort.

Scheduling, energy reporting and open APIs

7-day scheduling, automatic heat and cool changeover and HVAC energy reports come as standard. Open APIs plus Tuya and ZigBee ecosystems support OEM customisation and third-party platform integration.

No-rewire upgrade path

The SWB511 24Vac C-wire adapter reconfigures existing 3-wire or 4-wire HVAC wiring to power a smart thermostat. No new cable runs are required, which makes retrofits considerably faster.

North America thermostat models compared

All models run on 24Vac and are designed for North America residential and light-commercial HVAC.

Frequently asked questions

When and where is OWON exhibiting in autumn 2026?

OWON exhibits at the 140th Canton Fair, Phase 1, in Guangzhou from October 15–19, 2026 at booth 17.2M21, and at the HKTDC Hong Kong Electronics Fair (Autumn Edition) from October 13–16, 2026 at booth CH-B02 in the HKCEC, Wan Chai.

How do I find booth 17.2M21 at the Canton Fair?

Enter Area D and go to Hall 17.2, then follow Row M to position 21. The booth number 17.2M21 reads as hall 17.2, row M, stand 21.

What is the difference between the Open Protocol and Tuya editions of the PC471 Series?

The Open Protocol edition communicates over RS485 using Modbus RTU and Modbus TCP, and also supports MQTT and HTTP, so it can connect directly to your own cloud, EMS or BMS. The Tuya edition is pre-integrated with the Tuya ecosystem for the fastest route to market in connected-home and light-commercial projects. Both share the same hardware advantages: Ethernet and WiFi connectivity, a built-in dry-contact relay, CT-clamp measurement and a compact DIN-rail housing.

Which HVAC systems do OWON North America thermostats support?

All models run on 24Vac and support conventional systems, multi-stage heat pumps and dual-fuel configurations, covering most residential and light-commercial HVAC installations in North America.

Can OWON customise devices for our brand?

Yes. As an OEM/ODM manufacturer we provide device customisation, app customisation, private cloud deployment and third-party platform integration.
