Smart HVAC Control Solutions with WiFi Thermostats & Sensors
24VAC WiFi thermostats, remote room sensors and flexible system integration for HVAC manufacturers, system integrators, smart home brands and connected-building projects.
OWON provides smart HVAC control solutions designed for North American residential and light commercial 24VAC HVAC systems. The solution combines connected thermostats, wireless remote sensors, WiFi connectivity and API integration to support smarter HVAC control, remote management and scalable system deployment.
From heat pumps and dual-fuel systems to multifamily properties and connected HVAC products, OWON offers flexible thermostat platforms that can be selected and customized according to HVAC compatibility, application requirements and integration architecture.
Smart HVAC Control for 24VAC Systems
A reliable smart HVAC control solution starts with HVAC compatibility.
OWON WiFi thermostat platforms are designed around North American 24VAC HVAC architecture and support a range of conventional and heat pump applications, including:
• Conventional heating and cooling
• Multi-stage HVAC systems
• Heat pumps with auxiliary and emergency heat
• Dual-fuel / hybrid heating
• Automatic heating and cooling changeover
• Humidity-related HVAC control on supported models
Beyond basic temperature adjustment, the thermostats provide HVAC control functions such as equipment staging, compressor protection delays, temperature swing configuration and installer-level settings.
This allows HVAC professionals and equipment manufacturers to select a connected thermostat according to the actual HVAC system rather than simply adding WiFi connectivity to a basic thermostat.
WiFi Thermostat Platforms for Different HVAC Applications
Different HVAC projects require different combinations of equipment compatibility, sensing and user interaction. OWON provides several WiFi thermostat platforms for North American 24VAC applications.
PCT5231 – Heat Pump & Remote Sensor Applications
The PCT5231 WiFi thermostat is designed for conventional and heat pump HVAC systems, supporting up to 2-stage conventional and 4H/2C heat pump configurations.
Key capabilities include:
• Auxiliary and emergency heat
• Dual-fuel / hybrid heating
• Up to 10 wireless remote room sensors
• 7-day scheduling
• Temperature limits and thermostat locking
• Energy-related reporting
• HVAC maintenance reminders
It is particularly suitable for projects requiring broad heat pump compatibility and multi-room temperature monitoring.
PCT533 – Occupancy & Humidity Control
The PCT533 WiFi thermostat is designed for advanced residential and light commercial HVAC applications where environmental sensing and user experience are important.
Key capabilities include:
• 4.3-inch color touchscreen
• Occupancy sensing
• Temperature and humidity sensing
• Humidifier and dehumidifier control
• Remote sensor support
• Multi-stage heat pump control
• Auxiliary and emergency heat
• Dual-fuel applications
PCT533 is well suited to connected HVAC projects that require occupancy-aware operation or humidity management in addition to temperature control.
PCT513 – Multi-Room Temperature Management
The PCT513 WiFi thermostat supports up to 16 wireless remote sensors for applications requiring temperature information from multiple rooms.
Remote sensor data can support room prioritization and more flexible comfort management across larger residential properties.
Note: Remote room sensing should not be confused with true HVAC zoning. Independent HVAC zones may require additional zone controllers, dampers or separate HVAC equipment.
Connected HVAC Control in One Platform
Smart HVAC control involves more than controlling temperature from a mobile phone.
OWON combines thermostat control with sensing, connectivity and software capabilities to support a broader connected HVAC environment.
Remote Room Sensors
Wireless room sensors provide temperature information from locations beyond the thermostat itself.
For example, PCT5231 can connect with up to 10 remote room sensors, allowing the thermostat to use additional room-level information for temperature management.
WiFi & Remote Management
WiFi connectivity enables supported thermostat functions to be accessed through connected applications and cloud services, providing remote visibility and control without requiring users to be physically present at the thermostat.
Smart Scheduling
Flexible scheduling supports different temperature settings according to time of day and occupancy requirements, helping automate routine HVAC operation.
HVAC Protection
Installer-configurable functions such as compressor delay and temperature swing settings help the thermostat operate according to HVAC equipment requirements.
Energy Visibility
Supported thermostat platforms provide energy-related information that can help users and project operators better understand HVAC operation.
Retrofit Support
Many existing HVAC installations do not have a dedicated C-wire at the thermostat location.
For compatible retrofit applications, OWON provides the SWB511 C-wire Adapter as an installation option where adding new thermostat wiring would otherwise increase project complexity.
Open Integration for HVAC and IoT Platforms
For B2B projects, a thermostat often needs to become part of a larger HVAC, smart home or building platform.
OWON's smart HVAC control architecture supports integration capabilities including:
• Device-level API
• Cloud-level API
• MQTT / HTTP integration
• Secure cloud connectivity
• Mobile app integration
• Third-party cloud integration
• OTA firmware capability
• Custom firmware options
A typical connected architecture can be represented as:
WiFi Thermostat & Sensors → WiFi / Cloud → API → App / HVAC Platform / Third-Party System
This allows HVAC manufacturers, system integrators and IoT solution providers to incorporate thermostat control into their own applications and connected ecosystems.
Built for Professional HVAC Projects
OWON smart HVAC control solutions can support a range of professional applications.
HVAC Manufacturers
Integrate connected thermostat control into HVAC equipment portfolios or develop customized thermostat platforms for specific system requirements.
Smart Home & IoT Brands

Hotels & Light Commercial Buildings
Use connected thermostat platforms for room comfort, occupancy-related HVAC strategies and centralized system integration.
OEM & Custom Thermostat Solutions
For customers developing their own connected HVAC products, OWON provides OEM and ODM thermostat services in addition to standard thermostat platforms.
Customization options can include:
• Private-label branding
• Product appearance customization
• Hardware configuration
• Firmware customization
• HVAC control logic
• API integration
• Cloud platform integration
• Mobile app integration
• Communication module integration
• Product manufacturing and mass production
This allows an existing thermostat platform to serve as the foundation for a customer's own HVAC, smart home or connected-building solution.
Rather than developing thermostat hardware, HVAC control logic, connectivity and manufacturing infrastructure independently, B2B customers can select an existing OWON platform and customize it according to project requirements.
