(1) is controlled by a temperature controller.
In the fan-coil system, the thermostat is used to control the electric water valve, and the high, medium and low speed of the fan is manually controlled. The start or stop of the fan is interlocked with the electric water valve. General thermostats are equipped with switches in winter and summer. The temperature of the air-conditioned room can be automatically controlled by a thermostat.
(2) Key control of energy saving
Generally, the air-conditioned rooms of fan-coil units are equipped with energy-saving keys, which can start or disconnect the power supply of the fan and stop the operation of the fan. Some fan-coil systems with high requirements for use are also equipped with temperature switches, and their temperature set points are constant and cannot be adjusted, so that the room temperature can be controlled within a certain range.
