In general, the majority of fan coil models do not have humidifiers built in. There are some exceptions, and certain buildings have separate humidifiers with a local humidistat controller installed at the fan coil unit.
If your unit has a built in humidifier, Nextech may be able to integrate the humidifier with the smart thermostat and eliminate the need for a separate humidistat. This is typically a custom quoted service unique to your specific unit.
