GENERAL
The T6620 series thermostat is a stand-alone microprocessor based thermostat with LCD display. The thermostats are designed to on/off control the fans, valves, compressors or electric heaters in fan-coil and air-conditioner applications.
Models are available for heating/cooling control of 2-pipe or 4-pipe fan-coil units.
The thermostats accept an external energy savings input that overrides the heating/cooling temperature setting for increased energy savings.
