The Smart Variable Air Diffuser (SVAD) has received another significant upgrade. Evolving from Version 2.2 to Version 3.3.3, this release introduces significant software enhancements along with expanded hardware capabilities. New features include infrared remote control, dual-band 5G Wi-Fi connectivity, Window Switch energy-saving integration, and flexible property management control modes. Together, these enhancements further improve the intelligence, energy efficiency, and security of building automation systems, providing smarter and more reliable airflow control for modern buildings.
Control Upgrade: Infrared Handheld Remote Control Added
1.Flexible Expansion
By simply adding a remote receiver module (with built-in buzzer), the SVAD can be controlled via a handheld infrared remote controller.
2.Multi-Unit Control
A single remote controller can operate multiple units individually, making inspection and maintenance more convenient.
3.No Interference
As an additional control option, it does not affect the existing control logic of the wall-mounted thermostat, mobile app, or BA (Building Automation) system.
Temperature Control：Customizable Setpoints, Ensuring Comfort and Efficiency by Preventing Overcooling or Overheating
1.Pain Point Resolution
Old version fixed 16–30°C range; new version allows custom limits via BA system within the same range.
2.Management Value
Prevents extreme temperature settings, reducing complaints and energy waste.
3.Parameter Support
Supports reading and writing of minimum and maximum limit settings, flexibly adapting to the needs of various scenarios.
BMS Point Name | Default Setting | Setting Range | Access |
Min Limit of Temperature Setting Range | 16 | 16~30 | R/W |
Max Limit of Temperature Setting Range | 30 | 16~30 | R/W |
Communication Enhancement: Modbus RTU now supports odd/even parity
1.Full Compatibility
Breaking away from the old version's "none parity" limitation, V3.3.3 adds support for odd and even parity
2.Stable Networking
Offers multiple baud rate combinations from 9600 to 38400 (12 modes total), ensuring seamless integration of SVAD with various field devices and more stable communication
BMS Point Name | Default Setting | Setting Range | Access |
Baud rate | 0 | 0：9600 none parity 1：14400 none parity 2：19200 none parity 3：38400 none parity 4：9600 odd party 5：14400 odd party 6：19200 odd party 7：38400 odd party 8：9600 even parity 9：14400 even parity 10：19200 even parity 11：38400 even parity | R/W |
Network Connectivity: Dual-Band WiFi (2.4G + 5G) Support
1.Ultra-Fast Network Configuration
Adds 5GHz band support alongside the original 2.4GHz
2.Enhanced Anti-Interference
Automatic dual-band optimization significantly improves network configuration speed and connection accuracy, ensuring robust performance in high-density wireless environments
Energy-Saving: Smart Window Switch Interlock
1.Behavior-Based Energy Saving
When enabled, opening the window (Window Switch disengaged) forces the damper to close and triggers an ER5 alarm.
2.Dual Protection
Prevents energy waste from "air conditioning with windows open" while avoiding condensation damage to ceilings.
3.Status Visibility
Real-time Window Switch status upload, with three configurable modes: Enable/Force Close/Disable.
BMS Point Name | Default Setting | Setting Range | Access |
Window Switch Configuration | 1 | 0: Window Switch Disabled 1: Window Switch Forced Closed 2: Window Switch Enabled | R/W |
Window Switch Status | -- | 0: Window Switch Open 1: Window Switch Closed | R |
Security Enhancement: One-click WiFi Shutdown
1.Compliance Assurance
Designed specifically for high-security environments such as banks and government facilities.
2.Physical Isolation
Once WiFi is disabled, the device cannot be discovered or paired via the app, the WiFi icon is hidden on the panel, eliminating potential external network intrusion threats and meeting the highest information security standards.

Operational Empowerment: Arrears Alarm & Forced Shutdown
1.Tiered Control
* ER6 (Early Warning): In the early stage of tenant arrears, temperature settings are locked, the system continues operating under current conditions, and an alarm is displayed on the screen.
* ER7 (Shutdown): In case of prolonged arrears, the damper is forced to close, an alarm is displayed on the screen, and user operation is disabled.
2.A Good Helper of Management
Empowers property managers with robust remote control capabilities, effectively improving the collection rate of management fees.
BMS Point Name | Default Setting | Setting Range | Access |
Alarm Function | 0 | 0: No Alarm 1: ER6 Alarm 2: ER7 Alarm | W |
