Wirelees WIFI thermostat for PTAC and Heat Pump

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 However, many buildings—especially hotels, motels, and apartments—still rely on outdated thermostats for their PTAC (Packaged Terminal Air Conditioner) or heat pump systems.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.

Core Feature 1: Larger LCD Touchscreen for Intuitive Operation

The CH7400 reimagines the user experience with a large, sleek touchscreen and negative LCD display, ensuring system status is instantly clear. Whether checking temperatures or switching modes, all operations are easy to read and execute with a single tap.

Users can effortlessly access:

● Operating modes: Off, Cool, Heat, Auto, Emergency Heat

● Fan settings: On/Auto

● Scheduling options: Manual or programmable

Ideal for guests or tenants unfamiliar with HVAC systems, the intuitive layout minimizes confusion and reduces unnecessary service calls.

Core Feature 2: Wi-Fi Smart Remote Control

Embedded with Tuya WiFi smart home technology, the CH7400 enables remote control of room heating/cooling via smartphones:

● For property managers: Monitor and adjust multiple units without entering each room

● For homeowners: Modify temperatures anytime, anywhere for maximum convenience
