Abstract:
A fan control system according to the present disclosure includes a controller that selects a control mode from a plurality of control modes including a first mode and a second mode. The first mode is a control mode in which an electric signal is given to fan motor so that fan motor operates at the first rotation speed. The second mode is a control mode in which an electric signal is given to fan motor so that fan motor operates at a second rotation speed lower than the first rotation speed. The controller has a function of selecting the second mode in a period after the start of the fan motor and before the selection of the first mode.
