We started with the manufacture of sensors and transducers designed to sense and transmit temperature, humidity and pressure readings to other control equipment. Our product line has evolved to include state-of-the-art controls for building automation. With advances in microprocessors, we developed the "S" Series of microprocessor-based controls and, more recently, our line of Superstats. While all of our thermostats and controls offer unsurpassed functionality and control as stand alone programmable thermostats, any of our Superstats and "S" Series thermostats and controllers can be programmed and monitored using a local or remote PC running On Site Operating Engineer, our free Windows(TM) based communications and interface design software
