Product Description

The SAS810FCT series is a professional-grade digital fan coil thermostat engineered for seamless integration into sophisticated HVAC systems. Specifically designed for Central AC units, the Modbus RTU models enable robust communication with Building Management Systems (BMS) via RS485, facilitating precise, centralized control for optimal energy management across commercial properties. For residential or smart environments, the WiFi models offer intuitive remote operation. Featuring a large LCD and supporting both 2-pipe and 4-pipe configurations, the SAS810FCT series delivers reliable, high-performance climate management.

Key Functions

7-Day Programmability

Set customized temperature schedules for all seven days, optimizing climate control for comfort while significantly reducing energy waste during off-peak hours.
Modbus RTU Protocol

The Modbus-enabled version allows for centralized monitoring and control by integrating with existing Building Management Systems (BMS) via RS485 communication.
WiFi Connectivity

WiFi models enable remote control of the thermostat settings, fan speed, and mode via a dedicated mobile application, offering convenience and flexibility.

2/4 Pipe System Control

Easily switch between two-pipe (heating or cooling) and four-pipe (simultaneous heating and cooling) system configurations to suit diverse HVAC needs.
Data Retention Feature

All user settings, including temperature setpoints and programming schedules, are permanently stored, eliminating the need for battery backup during power outages.
Auto/3-Speed Fan Selection

Choose between automatic fan operation or manually select from three distinct fan speeds (High, Medium, Low) to manage airflow and noise levels.
