Figure 6 is a signal flow diagram showing the operation of the heating setting controller of the heating control unit according to the control method of the present invention. As shown in FIG. 2, the heating setting controller 200 of the heating control unit 150 receives a signal of the heating temperature setting key in step 602 when a predetermined key signal is input from the key input unit 220 in step 600. If it is determined that the signal is a heating temperature setting key, in step 604, the heating temperature of the room corresponding to the signal of the heating temperature setting key is set, and the set heating temperature is displayed on the temperature display unit 230.

If it is not the signal of the heating temperature setting key in step 602, the heating setting controller 200 determines whether it is a signal of the room selection key in step 606, and if it is a signal of the room selection key, step 608 ) Sequentially selects rooms for which the heating time is to be reserved according to the input of the room selection key signal, and displays them on the reservation display unit 240.

As shown in the drawing, when the time interrupt is applied at a predetermined time interval, the heating setting controller 200 determines whether there is a change in the setting state of the heating temperature and the heating time in step 700. By performing the operation of FIG. 6 as described above, it is determined whether the set state of the heating temperature and the heating time is changed. When the setting state is not changed as a result of the determination of step 700, the heating setting controller 200 ends the time interrupt operation. When the setting state is changed as a result of the determination of the step 700, in step 702, a packet as shown in FIG. 4 is generated according to the changed setting state, and the generated packet is transmitted to the transmitting unit in step 704. The signal is output to 250 and transmitted through the antenna ANT1.

It is determined whether the packet transmitted in step 704 is identical, and when the two packets match, it is determined that the packet is transmitted normally, and the time interrupt operation is terminated. If the packet is not received in step 706 or if the packet does not match in step 708 even if the packet is received, the heating setting controller 200 sets an example of a predetermined reception waiting time set in step 710. For example, it is determined whether 3 seconds have elapsed, and when the set reception waiting time has not elapsed, the process returns to step 706 to repeat the operation of determining whether or not the packet is received and whether the received packet matches.

If the received packet is not received or the received packet does not match even after the reception waiting time set in the step 710 has elapsed, the heating setting controller 200 may set an example of an abnormal number of times for the packet in step 712. For example, it is determined whether the transmission has been repeated five times or more, and when the transmission has not been repeated more than the set number of times, the method returns to step 704 to retransmit the packet, and then determines whether the packet is received and whether the received packet matches. If the matching packet is not received even after repeatedly transmitting the packet more than the set number of times, the heating setting controller 200 determines that the packet is not transmitted normally, and in step 714 the alarm unit ( 270 to generate an alarm indicating that an error has occurred.
