The CH7100 is a premium 4.3-inch TFT high-resolution touch screen thermostat designed for advanced HVAC management. It offers a seamless interface for precise control of multi-stage heating and cooling systems in both residential and commercial settings.
The CH7100 Wi-Fi Smart Thermostat is engineered for modern heat pumps with auxiliary heat control systems. Integrated with 2.4GHz Wi-Fi, it enables remote access via the Smart Life app, allowing you to program temperatures anytime, anywhere. The Geo-fencing function enhances efficiency by automatically adjusting settings based on your location.

This adapter adds the crucial C wire (Common wire) to power your smart thermostat, eliminating the need for extensive rewiring in homes lacking a C wire.


System Versatility: Compatible with Heat Pump (3H/2C), Conventional HVAC (2H/2C), and both 2-Pipe & 4-Pipe Fan Coil systems.
Dedicated Terminals: Includes specialized terminals for Emergency Heat (E) and Auxiliary Heat (W/AUX) to ensure comfort during extreme weather.
C-Wire Reliability: Requires a 24V Common Wire to ensure a stable, uninterrupted power supply for the high-resolution TFT display.
ISO Certified Production: Every CH7100 unit is manufactured in an ISO 9001:2015 and ISO 14001:2015 certified facility.
Compliance Standards: Fully certified with CE (RED/EMC/LVD), RoHS, and FCC marks for global market access.
OEM Experience: Backed by E-TOP Controls, a professional manufacturer with over 20 years of experience (since 2003) in ODM/OEM services.
