PROBLEM TO BE SOLVED: To provide a fan coil system of good operability. SOLUTION: To a two-wire signal line Ls from a transmission processor is connected an operation terminal device 4, and a fan coil control terminal device 3. To the fan coil control terminal device 3 is connected a fan coil unit 2 for switching ventilation capacity thereof in 3 stages of [Strong], [Intermediate] and [Weak]. The operation terminal device 4 is provided with a first switch for setting the ventilation capacity of the fan coil unit 2 to the [Strong] step, a second switch for setting that to the [Intermediate] step, a third switch for setting that to the [Weak] step, a fourth switch for turning ON/OFF a power source, and operation push buttons P1 , P2 , P3 , P4 respectively of each switch are exposed from the front of a case 40. When push buttons P1 through P4 are operated, the transmission processor 1 creates control data based on returned data returned from the operation terminal device 4 to the transmission processor 1, so that the fan coil unit 2 is controlled. |
