Control is performed as follows.

When a predetermined number of call signals are transmitted, the switching function connects the telephone line 2A and the control circuit 20,
The control circuit 20 becomes operational based on the operation signal from the external telephone, and a first chime sound is generated to confirm this to the user operating the external telephone. When the user confirms this first chime sound, the user enters D according to the 4-digit password set in advance as an operation signal.
'1' MF is sent out. At this time, if DTMF cannot be sent out from the external charger used, -off control cannot be performed.

After sending out the PIN number, if you press the specified push button (#) to indicate the end of transmission to further send DTMF, the PIN number will be verified, and if the amount matches the preset PIN number, a second chime sound will be generated. . If it does not match the password, the first chime sound is generated again, so DTMF is sent again according to the password. The password can be retransmitted up to three times, but if an incorrect signal is transmitted the third time, the line will be disconnected.

After the second chime sound is generated, the user operates the one-digit number corresponding to the device he wants to control and the one-digit number that is the activation signal, and then presses the predetermined push button (#) indicating the end of transmission. ) to send out DTMF.

Here, the automatic bathtub with water heater 3, the air conditioner 4, the lighting equipment 5, the electric lock 6, and the gas cutoff valve 7 each receive a signal to perform a predetermined operation according to each device, as described above.
