Who is E-TOP?

Founded in 2003, E-top is a premier ISO 9001:2015 and ISO 14001:2015 certified manufacturer with over 20 years of dedicated expertise in the thermostat industry. Operating from an 8,000 m² professional facility, we specialize in high-end ODM/OEM solutions for global heating and cooling markets. Our mission is to combine innovation with passion to create a smarter, sustainable "Green World" through precision climate control.

 

 

Our Manufacturing & R&D Power

We provide a full-chain manufacturing service, including SMT, Plug-in, Injection, Silk Printing, Assembly, and rigorous Aging Tests.

Production Capacity: 5,000+ units per day with a 95%+ on-time delivery rate.

Professional R&D: Supported by a 20-member R&D team, we utilize advanced tools like FMEA, APQP, and PPAP to ensure world-class product development.

Core Algorithm Technology: Instead of legacy 0% or 100% on/off switching, our proprietary Adaptive PID and PWM algorithms dynamically adjust the power duty cycle. This achieves perfectly smooth, constant temperature control, maximizes energy savings, and protects HVAC equipment from thermal stress.

 

Connectivity Leadership:

We are at the forefront of IoT integration, supporting:

Smart Ecosystems: Official integration with Tuya Smart, Smart Life, Amazon Alexa, and Google Assistant, and Matter.

Industrial Protocols: BACnet, Modbus, KNX, and OpenTherm.

Wireless Standards: Zigbee, LoRaWAN, RF (433/868/915MHz), and Bluetooth.

App Support: Seamless mobile control via App Store and Google Play applications.
