The Fan Coil Communicating Thermostat is specifically designed for fan coil control. The product features a backlit LCD display with dedicated function menu buttons for simple operation. Accurate temperature control is achieved due to the product’s PI proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based thermostats. Three additional inputs are provided for monitoring and/or various advanced functions. The Fan Coil Communicating Thermostat features configurable System, Fan button functions, and a SPST auxiliary switch that can be used to control lighting or auxiliary reheat.
