[0016]
Reference numeral 20 denotes a remote control device, which is electrically connected to the control board CB of the heat source device 30 via a connection cord 44.
[0017]
As shown in FIG. 2, the remote control device 20 includes a wired remote control base 41 fixed to a wall surface 43 of a conditioned room, and a wireless remote control body 42 that is detachably attached to the remote control base 41. .

[0018]
Next, the trial operation of the floor heating system will be described with reference to FIG.
[0019]
The trial operation according to this embodiment is an operation for checking whether hot water is correctly supplied to the hot water floor mat 11 when the hot water floor mat 11 is laid.
[0020]
When performing a trial run (S1), when the remote control body 42 is removed from the wired remote control base 41 fixed to the conditioned room, a remote control attachment / detachment switch (not shown) is turned on (S2). The construction worker turns on the trial operation switch arranged in the heat source unit 30 and installs the remote control main body 42 on the hot water pipe 60 of the hot water floor mat 11 as shown in FIG. Next, after elapse of a predetermined time (for example, 20 seconds) (S3), the floor temperature is detected via the temperature sensing element 46, and this temperature information is input to the processing unit 61 (S4). Wireless transmission is performed from the infrared light emitting unit 45 to the infrared light receiving unit 47 of the remote control base 41 (S5). The temperature information from the infrared light receiving unit 47 is sent to the control board CB via the connection cord 44, and the control board CB controls the operation of the heat source unit 30. If hot water is correctly supplied to the hot water pipe 60, that is, if there is no abnormality in the heat source device 30 and the piping system, for example, the number of times of detection after every 20 seconds has passed, the floor temperature should rise to a predetermined temperature. If the temperature rises to a predetermined temperature, it is determined that the trial run is finished (S6), and then the trial run is finished.
[0021]
According to this, since the temperature sensing element 46 built in the remote control main body 42 can be used for detecting the floor temperature at the time of trial operation, a dedicated floor temperature detecting element that has been conventionally required, a lead wire for connecting it, etc. Can be eliminated, and the cost can be reduced and the convenience of temperature detection during trial operation can be improved. In addition, since the floor temperature information is transmitted and received wirelessly, the floor temperature at an arbitrary location can be detected, and the installation location of the remote control device 20 is not restricted.
[0022]
When performing normal operation, the processing flow shown in FIG. 7 is followed.
[0023]
After the floor heating is started (S11), when the remote control main body 42 is removed from the remote control base 41 (S12), the temperature at the place where the remote control main body 42 is placed is detected by the temperature sensing element 46 (S13). The detected temperature information is input to the processing unit 61 (S14), transmitted from the infrared light receiving / emitting unit 45 to the infrared light receiving / emitting unit 47 of the remote control base 41 (S15), and this routine is repeated until the floor heating is completed. (S16, S17). On the other hand, if the remote control body 42 has not been removed from the remote control base 41 in S12, the temperature at the place where the remote control base 41 is fixed is detected by the temperature sensing element 46 (S18). The detected temperature information is input to the processing unit 61 (S19), transmitted from the infrared light receiving / emitting unit 45 to the infrared light receiving / emitting unit 47 of the remote control base 41 (S20), and this routine is repeated until the floor heating is completed. (S16, S17). In S20, the transmitted temperature information is transmitted directly from the processing unit 61 to the processing unit 41A side of the remote control base 41 via the electrical connection couplers 48 and 49 as shown in FIG. To the control board CB.
[0024]
According to this, even when the remote control main body 42 is fixed to the remote control base 41 or removed, the temperature sensing element 46 detects the room temperature, and floor heating control is performed based on this temperature information.
[0025]
The description of the specific embodiment is finished above, but the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, an infrared light receiving / emitting unit is used as a floor temperature information transmitting / receiving unit. However, the floor temperature information may be transmitted / received not only by infrared rays but also by ultrasonic waves. Even if the number of hot water floor mats is one, two, or four or more, the floor temperature can be easily detected by wireless communication.
[0026]
【The invention's effect】
As described above, according to the first aspect of the present invention, it is not necessary to prepare a separate floor temperature detecting element at the time of trial operation, and since the floor temperature information is transmitted and received wirelessly, the floor temperature at any place on the floor is detected. And the location of the remote control device is not restricted.
[0027]
According to the second aspect of the present invention, when the trial operation is finished and the normal operation is performed, the remote control main body is fixed to the remote control base so that the temperature detection sensor of the remote control main body can detect the room temperature. Can be used.
