The VT73xxC5x00 PI thermostat family is designed for fancoil control. The product features a backlit LCD display with dedicated function menu buttons for simple operation. Accurate temperature control is achieved with the PI proportional control algorithm, which virtually eliminates temperature offsets associated with traditional, differential-based thermostats. All models can control three, two, or single fan speeds. Three additional inputs are also provided for added functionality. All models feature configurable System and Fan button functions to meet a range of applications and an auxiliary contact that controls lighting or auxiliary reheating. All devices are also available with Echelon or BACnet MS-TP network adapters.
