The new Enerstat SC Series of thermostats are non-programmable, digital communicating units. The four thermostats in the series come with remote computer-controlled access, for commercial and residential applications. Using a standard hardware interface, all functions normally accessible through the thermostat’s keypad and display can be adjusted and communicated to heating and cooling systems at a data rate of 1,200 bits per second. The thermostats display time from a central clock. They can be used with outdoor temperature sensors.
