Models are available for heating/cooling/ventilating control of 2-pipe or 4-pipe fan coil units.
The fan speed can be manually controlled by the fan speed control pushbutton. It is wired to run high/medium/low speed continuously or to automatically change the fan speed, while with other models there is a choice of running the fan continuously, or cycling it with the thermostat
