CPU31 when receiving the output signal of switch 87 from input/output interface 33, based on this output signal, use timer 34 to measure and play this from (rising edge of the signal of Fig. 6) when starting to press switch 87 and press the time being released from till (trailing edge of signal).CPU31 the time measured less than the time predetermined time, make the first function effective, the order 43 being used for volume adjustment exported rheostat 24.Can on the other hand, when this time measured is more than the time predetermined, long CPU31 makes the second function effective on time, will be used for switching order 31A (aftermentioned) output that receive the output signal from switch 80～84 to storage part 32.Additionally, in the present embodiment, as shown in Figure 6, for judge long by the time predetermined be 5 seconds, but be not limited to 5 seconds.

<process that the operation of switch 87 receives>

Fig. 7 is the process chart of the reception of the operation with the switch 87 about volume adjustment involved by present embodiment.The program following this flow chart is stored in advance in storage part 32.CPU31 reads this program from storage part 32, controls each portion by performing read-out program.

Output signal from input/output interface 33 is analyzed by CPU31, judges that whether this output signal is the signal (step S1) of the push of the switch 87 representing volume based on the result analyzed.

When be judged as output signal be not from switch 87 signal time (step S1: "No"), CPU31 repeat step S1 process.On the other hand, when being judged as the operation of switch 87 (step S1: "Yes"), CPU31 based on this output signal, use timer 34 judge switch 87 by according to time be whether the operation of the time (5 seconds) predetermined more than, i.e. switch 87 be whether that the length of more than 5 seconds is by (step S3).

When be judged as long by (step S3: "Yes"), CPU31 makes the second function effectively (step S5).In step s 5, the order 31A being used for can the operation except at least one switch in the more than one switch closed beyond 87 in the multiple switches that receive operating portion 8 be switched over is exported storage part 32 by CPU31.Storage part 32 carrys out the value of overwritten area 325 according to order 31A.Thus, if the original value of mark FL is " permission ", then it is rewritten as " not allowing ", if original value is " not allowing ", is then rewritten as " permission ".

The value of the mark FL after rewriteeing is judged (step S7) by CPU31, controls speaker 11 or LED group 9 (step S9～S15) based on judged result.

Specifically, when the value indicating FL is rewritten as " not allowing " (or 1), CPU31 will make the glimmer control signal of 1 time of LED90～91 export input/output interface 33 (step S9), and will be used for instruction 41 output reading " not allowing " data to sound rendering IC22 (step S11).The search part 230 of sound rendering IC22 retrieves table 221 based on the instruction 41 from CPU31.The voice data of " (police whistle sound 1 time) and ' locked ' " that read from table 221 by this retrieval is exported speaker 11 via sound amplifying circuit 23 by sound rendering IC22.

By the 1 of such LED90～91 glimmer (within 0.5 second, light, within 0.5 second, extinguish) and the voice message from speaker 11, it is indicated being set to the notice of this meaning of lock-out state to user.

Additionally, when the value indicating FL is rewritten as " permission " (or 0), CPU31 will make the glimmer control signal of 2 times of LED90～91 export input/output interface 33 (step S13), and sound rendering IC22 (step S15) is arrived in instruction 41 output that will be used for reading " permissions " data.The search part 230 of sound rendering IC22 retrieves table 221 based on the instruction 41 from CPU31.The voice data of " (police whistle sound 2 times) and ' unlocking ' " of being read from table 221 by this retrieval is exported speaker 11 via sound amplifying circuit 23 by sound rendering IC22.

Glimmered (within 0.5 second, light, 0.5 second extinguish) by the 2 of such LED90～91 times and from the voice messages of speaker 11, the notice of this meaning that is indicated unlocking to user.

On the other hand, CPU31, when be judged as it not being the length (step S3: "No") on time of switch 87, makes the first function effectively (step S17).In step S17, CPU31 will order 43 outputs to arrive rheostat 24.Thus, rheostat 24 can change resistance value according to order 43, thus changing the volume from speaker 11.

<process that the operation of switch 80～84 receives>

Fig. 8 is the process chart that the operation about switch 80～84 involved by present embodiment receives.The program following this flow chart is stored in advance in storage part 32.CPU31 reads this program from storage part 32, controls each portion by performing read-out program.

CPU31 judges whether to have carried out operating (step S21) to the switch of operating portion 8 based on the output from input/output interface 33.When being judged as switch not being operated (step S21: "No"), repeat step S21, when being judged as switch has been carried out operation (step S21: "Yes"), CPU31 judges the kind (step S23) of the switch pressed based on the output signal from input/output interface 33.

At this, the identifier of the output signal packet of the switch that CPU31 receives via input/output interface 33 input terminal (terminal X0～X7) containing this output signal.Based on the identifier in output signal, CPU31 can judge that the output signal received is the output signal of which switch in switch 80～87.

When the switch being judged as judging is some that namely switch that the function to operation device 2 is controlled switchs in switch 86A, 86B and 87 beyond 80～84, CPU31 then judges whether operated switch is switch 87 (step S25).When being judged as that operated switch is switch 87 (step S25: be "), transfer to the step S1 of Fig. 7, be judged as be not switch 87 time (step S25: "No"), transfer to step S27.In step s 27, CPU31 implements process corresponding with the output signal of the switch pressed.This process is known process, therefore not repeat specification.

On the other hand, CPU31 when being judged as that in step S23 operated switch is some in switch 80～84, the then value (step S29) of judgement symbol FL.When indicating that FL represents " permission " (step S29: " permission "), CPU31 will export water heater 1 (step S31) with from the corresponding control signal of the output signal of operated switch.

On the other hand, when indicating that FL represents " not allowing " (step S29: " not allowing "), when in the locked state switch 80～84 having been carried out operation, CPU31 implements the process (step S35) of operating condition based on water heater 1.

In step s 35, specifically, when pressing switch 81～83, when the switch relevant with the change of the operating condition of water heater 1 (operation start/stopping, automatic bathing, reheating etc.) has been carried out operation, if the operating condition corresponding with this switch of water heater 1 is in beginning state (in operating), then CPU31 switches to the control signal of halted state (operating stops) exporting water heater 1 by being used for.

It addition, if the operating condition corresponding with this switch of water heater 1 is in halted state (in operating stopping), then CPU31 does not receive operation content (ignore or abandon the output signal from switch).Thus, the control signal produced by this switching manipulation is not exported water heater 1 by CPU31.It addition, now, the instruction 41 being used for reading " cancellation " data is exported sound rendering IC22 by CPU31.The search part 230 of sound rendering IC22, based on the instruction 41 from CPU31, reads the voice data of " police whistle sound 3 times " from table 221.Read-out data are exported speaker 11 via sound amplifying circuit 23.Thus, export 3 police whistle sounds from speaker 11 and user's notice is not received operation (eliminating operation).

It addition, in step s 35, when switch 84 has been carried out operation, CPU31 does not receive operation, exports above-mentioned cancellation sound.
