The wired communication means 10 sends data to the heat source wired communication means 8 via the communication lines 16a, 16b and 16c. The heat source wired communication means 8 sends to the heat source control means 9 a system number indicating which communication line has received the operation signal and an operation request signal.
[0016]
When the heat source control means 9 receives the operation request signal, the heat source control means 9 determines the instructed system number, opens the opening / closing part 5a or 5b or 5c of the corresponding floor warming heat dissipation panel, and warms the heat dissipation panel by supplying hot water, thereby heating operation.

Therefore, even if there is an adjacent system, it does not malfunction.
[0017]
(Example 2)
Next, Embodiment 2 of the present invention will be described with reference to FIG. In the figure, information of the system number a is also added to the operation instruction data from the wireless floor heating remote controller 3a (s1). Upon receiving this information, the repeater first returns a response (ACK) to the wireless floor warming remote controller 3a (s2), and then transmits an operation on signal of the system a to the heat source device using the signal line 16a (s3). . The heat source unit 1 returns a response (ACK) to the repeater 4 (s5), turns on the opening / closing part 5a of the instructed system a, and starts heating combustion (s4).

Moreover, a system can be realized at low cost by using a plurality of wireless floor heating remote controllers and controlling a plurality of floor heating radiating panels with one repeater.
[0020]
(Example 3)
Next, Example 3 will be described. FIG. 3 is a block diagram according to the third embodiment. The repeater wired communication means has one transmission / reception port (Pio). The heat source wired communication means is connected by three communication lines 16a, 16b, and 16c, and SWa, SWb, and SWc are controlled by controlling the Pa, Pb, and Pc ports through which communication line to communicate with the heat source. Is determined by switching. SWa, SWb, and SWc are TTL.
[0021]
FIG. 4 is a timing chart of the third embodiment. When there is no data received from the communication lines 16a, 16b, and 16c, Pa, Pb, and Pc are periodically switched to check whether data is received (s1 to s3). If data comes from the communication line 16a (s4), the received data can be confirmed with Pio when Pa is turned on again (s5). If the data can be confirmed with Pio, data is taken in while Pa is kept on until data reception is completed (s5 to s6). When the data reception is completed, Pa, Pb, and Pc are periodically switched again to wait for the next reception (s7).

Example 4
Next, Example 4 will be described. FIG. 5 is a timing chart in the fourth embodiment. The wireless floor heating remote controllers 3a, 3b, 3c are provided with temperature setting means 13a, 13b, 13c, respectively. Here, the wireless floor heating remote controller 3a will be described as an example. When the heating operation switch 7a is turned on, temperature setting level information (here, 1) is transmitted to the repeater 4 simultaneously with the operation instruction. The repeater 4 gives an operation instruction to the heat source according to the operation instruction (P1). Since the temperature control of the floor heating radiating panel is controlled by how long (T2, T3) the heating hot water is supplied during a certain period (T1), the heating DUTY control means 15 in the repeater 4 is a wireless floor heating remote controller. It is confirmed that the temperature setting instructed from is 1, and the heating hot water supply time is determined to be T2.
[0024]
When the time T2 elapses, the heating DUTY control means 15 issues a heating off instruction to the repeater wired communication means 10, and a heating stop instruction is transmitted to the heat source. The wireless floor heating remote controller 3a transmits temperature setting information to the repeater again in order to instruct the heating on time of the next cycle when approximately T1 time has elapsed (P2).
[0025]
Next, when the temperature setting level is changed to 2 on the remote control side, the wireless floor heating remote control 3a transmits the temperature setting information to the repeater when approximately T1 time has elapsed (P3). Receiving this information, the heating DUTY control means 15 changes the room temperature by setting the next heating on time as T3 with T1 as it is and changing the heating on time. When the temperature setting is changed to the higher side, T2 <T3.
[0026]
By controlling heating-on DUTY with a repeater as described above, it is not necessary to perform wireless communication when heating is turned off in the middle of the T1 cycle, and effective use of radio waves is achieved, thus realizing a system with good responsiveness. it can.
[0027]
(Example 5)
Next, Example 5 will be described. FIG. 6 is a timing chart in the fifth embodiment. The wireless floor heating remote controllers 3a, 3b, and 3c include room temperature detecting means 14a, 14b, and 14c, respectively. Here, the wireless floor heating remote controller 3a will be described as an example. When the heating operation switch 7a is turned on, the temperature setting information (here 20 ° C.) and the current room temperature information (here 15 ° C.) are transmitted to the repeater 4 simultaneously with the operation instruction.
[0028]
The repeater 4 gives an operation instruction to the heat source according to the operation instruction (P6). Since the temperature control of the floor heating radiating panel is controlled by how much time (T4, T5) heating hot water is supplied during a certain period (T1), the heating DUTY control means 15 in the repeater 4 is a wireless floor heating remote controller. It is confirmed that the temperature setting instructed from is 20 ° C. and the room temperature is 15 ° C., and since the room temperature has not reached the setting, the heating hot water supply time is determined as a larger T4.
[0029]
When T4 time elapses, the heating DUTY control means 15 issues a heating off instruction to the repeater wired communication means 10, and a heating stop instruction is transmitted to the heat source. The wireless floor heating remote controller 3a transmits the temperature setting information and the room temperature information again to the repeater in order to instruct the heating on time of the next cycle when approximately T1 time has elapsed (P7).
[0030]
Next, when the room temperature rises to 20 ° C. on the remote controller side, the wireless floor heating remote controller 3a transmits the temperature setting information and the room temperature information to the repeater when approximately T1 time has elapsed (P8).
Receiving this information, the heating DUTY control means 15 sets the next heating on time as T5 with T1 as it is, and controls the temperature by changing the heating on time. In this case, since the room temperature has already risen to the set temperature, T5 is set to a small value, and T4> T5.
[0031]
By controlling heating-on DUTY with a repeater as described above, it is not necessary to perform wireless communication when heating is turned off in the middle of the T1 cycle, and effective use of radio waves is achieved, thus realizing a system with good responsiveness. it can.
[0032]
