In the system shown in FIG. 11, in the transmission processing device 1, a plurality of operation terminals 4 for monitoring the operation state of the switch and a plurality of control terminals 3 for controlling the load 2 are connected via a two-wire signal line Ls. The transmission processing device 1 remotely controls the operation of the load 2 based on a switch operation, and the transmission processing device 1 monitors the operation state of the load 2. Here, a unique address is set for each of the terminals 3 and 4.

The transmission processing device 1 sends out a transmission signal Vs having a format as shown in FIGS. 12A and 12B to the signal line Ls. That is, the transmission signal Vs includes a start pulse ST indicating the start of signal transmission, mode data MD indicating a signal mode, address data AD, control data CD for controlling a load, checksum data CS for detecting a transmission error, and a control terminal. 3 and a signal return period WT for setting a return period of a return data signal from the operation terminal 4 and is a multipole (± 24 V) time division multiplexed signal, and data is transmitted by pulse width modulation. ing.

In each of the control terminals 3 and the operation terminals 4, the address data AD transmitted by the transmission signal Vs received via the signal line Ls has its own address (unique address) set in advance. If they match, the transmission signal V

In response to the signal return period WT, return data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via an appropriate low impedance).

The transmission processing device 1 is provided with a dummy signal transmitting means and an interrupt processing means. The dummy signal transmitting means constantly transmits a dummy transmission signal in which the mode data MD is set to the dummy mode. Further, when the interrupt signal Vi as shown in FIG. 12C is returned, the interrupt processing means detects the operation terminal 4 that has generated the interrupt signal Vi, and accesses the operation terminal 4 to access the operation terminal 4. Return data is returned from the operation terminal device 4 that has generated the interrupt signal Vi. That is, the dummy transmission signal is always transmitted to the signal line L by the dummy signal transmission means.

In this way, the transmission processing device 1 can acquire the address of the operation terminal 4 that has generated the interrupt signal Vi.

When the transmission processing device 1 acquires the address of the operation terminal 4 that has generated the interrupt signal Vi, the control for transmitting to the control terminal 3 to which the load 2 whose correspondence with the switch is set in advance is connected is performed. In addition to generating data, a transmission signal Vs including the control data is transmitted to the signal line Ls, and the control data is transmitted to the corresponding control terminal 3 to control the load 2.

Strong, medium,
Since it is associated with weak, power on / off, the name sheet is set to “strong” by appropriately setting the load number on an existing operation terminal equipped with four switches used for lighting control and the like.
By replacing the name sheet with characters such as “medium”, “weak”, and “on / off”, the operation terminal used for lighting control and the like can be used as the operation terminal of the fan coil system. There is an effect that can be.

According to a fifth aspect of the present invention, in the third aspect of the invention, the operation terminal includes a power supply circuit for obtaining a power supply for operating an internal circuit from a transmission signal transmitted from the transmission processing device through the signal line. Therefore, there is no need to separately provide a wiring for supplying power to the operation terminal, so that the number of wirings can be reduced and the construction is facilitated.

According to a sixth aspect of the present invention, in the first to fifth aspects of the present invention, since the operating device includes a display element for displaying a state of the switch, the state of the switch can be easily confirmed from outside. It is possible to know the state of the fan coil unit.

According to a seventh aspect of the present invention, in the first to sixth aspects of the present invention, a maximum of three cases are provided in a mounting frame for a wiring device such that the front surface of the case is exposed from an opening window of the mounting frame. It is formed to a size equivalent to three wiring units of unit size that can be connected and mounted up to the mounting frame, and a mounting part for mounting to the mounting frame is formed, so that an embedded wiring device such as an outlet is provided. The construction method can be performed in the same manner as that described above, and there is an effect that the construction work is facilitated for the construction company.

According to a ninth aspect of the present invention, in the third aspect of the present invention, the case of the terminal for controlling the fan coil is formed to have an integral multiple of the size of the common type circuit breaker for the light distribution board. A mounting part for mounting to a panel connection mounting plate that is fixed inside and can be connected to a contract type wiring breaker for a light distribution board is formed, so a fan coil control terminal is connected to the panel It can be easily arranged in the distribution board via the mounting plate, and there is an effect that the installation work and the wiring work can be simplified.
