Core technical advantages – multi-area collaboration, stable and reliable, flexible expansion

Full-scenario protocol compatibility
Supports mainstream protocols such as Modbus, BACnet, Zigbee, KNX, and can customize private protocol docking to achieve cross-brand device linkage;
The unique “protocol conversion engine” of the dual-zone receiver can simultaneously parse heating (Modbus) and hot water (BACnet) signals.
Industrial-grade reliability design
Wired products use metal shielding shell (IP44 protection), wireless products have built-in adaptive frequency hopping technology (AFH), and the anti-interference ability is improved by 30%;
The dual-zone receiver has passed 100,000 switch tests, with a mean time between failures (MTBF) of >87,600 hours, and complies with the EN 60730 safety standard.
Modular customization capability
The number of interfaces, communication rate, and shell size can be customized on demand, and OEM laser engraving brand logos are supported;
Wireless products provide white label solutions, and customers can define the APP interface and control logic independently.
Global certification qualifications
CE, FCC, RED, RoHS 3.0 certifications, dual-zone receivers additionally comply with EN 12094-2 industrial burner control standards, and support exports to Europe, America, the Middle East and other markets.
