22. Reference numeral 23 denotes a second remote controller, and variable resistor 24.23 serves as a second setting means. It is equipped with a priority display LED 25 and a switch 26 for changing the set temperature. 27 is a priority controller, which is configured as follows. Set temperature TRA+T

。The operation of the above configuration will be explained below. When the switch 26 is off, VRa is at Vcc, which is an extremely high voltage, that is, the highest set temperature. At this time,
Since VRA<vCC, VRA<vRB, the output of the comparator 30 becomes LO, the analog switch 34 turns off, and the LED 25Vi does not light up. Since the inverter 32 output becomes old, the analog switch 33 is turned on and the gate circuit 31 selectively outputs VRA. On the other hand, the output of the inverter 32 lights up the LED 22 to indicate to the first remote control device that priority is given.

Let's discuss the case where ' is set as the priority state. If the temperature TRB set by the variable resistor 24 of the second remote control device
When is higher than the length of the first remote control device, VRA<VRB, as described above, and
vR□ corresponding to the lower set temperature is selected.In the opposite case, TRA > TRB f V+u > V R
In case a), the output of the comparator 3o becomes Hl and the output of the inverter 32 becomes iLo, so the analog switch 33 is turned off and the LED 22 is turned off. On the other hand, the analog switch 34 turns on, the LED 25 lights up, and it is displayed that the remote control device 230111 has priority and the remote control device 20 has no priority, and the gate circuit 31 maintains the temperature set by the second remote control device 23.
