Indoor comfort management and smart energy control are key to building automation. However, many buildings—especially hotels, motels, and apartments—still rely on outdated thermostats for their PTAC (Packaged Terminal Air Conditioner) or heat pump systems. These older models typically feature basic mechanical buttons or small digital screens with limited functionality and no wireless capabilities.

To address this gap, we’ve developed the CH7400 WiFi Wireless Thermostat—a modern upgrade packed with powerful features designed to meet today’s smart building needs.
