Product Description
The SAS922PIT Modulating Thermostat is engineered for 2-pipe Fan Coil Units (FCU), utilizing advanced Proportional-Integral (PI) control to output a precise 0-10VDC analog signal. This enables continuous regulation of valves, drastically surpassing the efficiency and comfort of traditional ON/OFF or simple P control. The superior PI Modulating algorithm ensures the elimination of temperature offset, delivering a highly responsive and accurate temperature control solution. By incorporating Modbus RTU communication, the SAS922PIT integrates effortlessly into Building Management Systems (BMS) for centralized control and data monitoring. It is the superior choice for maximizing operational efficiency and realizing significant Energy Saving in commercial, hotel, and high-end residential environments. This functionality makes it the ideal BMS Compatible Thermostat for FCU systems.
