Product Description
The SAS920PIT Modulating Thermostat is a flagship HVAC controller for advanced two-pipe Fan Coil Unit (FCU) systems. Its core competitive advantage lies in its continuous control: utilizing a high accuracy ±0.5°C sensor to generate a reliable 0-10VDC or 4-20mA output. This superior modulating technology achieves significant energy savings and occupant comfort by smoothly adjusting valves, eliminating temperature swings common in older thermostats. Crucially, this smart controller offers superior connectivity: Modbus RTU ensures seamless BMS integration for automated commercial projects, and optional WIFI enables easy remote HVAC control for modern residences. It is the ideal low-voltage solution for installations demanding precision and sophistication.
