Fan coil thermostats and automation

Fan coil

— a fan coil unit is a device that cools or heats air by passing it through a system of pipes with a coolant circulating through them. In this case, the cooling or heating of the coolant is provided by another component of the system — a chiller, usually installed outdoors. Therefore, it would be more correct to call this type of temperature controller “for fan coil-chiller systems”. At the same time, such systems can be used not only for heating in the cold season but also for cooling in the heat; these features are often taken into account in automation for fan coil units.
