Then, when the test operation is completed, the temperature detecting device 28 is removed.

Next, a normal operation and a trial operation in floor heating of the above-mentioned hot water heating system 1 will be described.

First, the normal operation will be described. When the operation key 17 of the floor heating controller 9A is turned on,
The floor heating controller 9A executes normal operation processing based on a normal operation program as shown in FIG. That is, the operating lamp 18 and the operating portion of the LCD display unit 19 are lit and displayed, and the thermal operation is performed based on the room temperature detected by the room temperature detector 20 and the set temperature set by the temperature increase key 23 and the temperature decrease key 24.

The ON-OFF time of the thermal valve 8A is 2
The ON time is about 5 to 20 minutes (20 minutes as one cycle,
Minutes can be variably controlled within the range of continuous ON).

During this floor heating operation, the ON-OF of the thermal valve 8A is changed by the deviation between the set temperature and the room temperature every 20 minutes.
By calculating and controlling the F time, the amount of hot water supplied to the floor heating radiator 5A is controlled to control the room temperature to the set temperature.

Next, the trial run will be described. Heat source device 2, floor heating radiators 5A, 5B, floor heating controller 7
After installation of A and 7B, installation of hot air heating radiators 6 and 7, installation work of those pipes, wiring, etc. is completed, the floor surface of the heated room with floor heating radiators 5A and 5B attached, that is, The temperature detecting device 28 of the present invention is provided on the upper surfaces of the floor heating radiators 5A and 5B.
Is placed as shown in FIG. 4, and the connection plug 33 of the lead wire 34 of the temperature detecting device 28 is connected to the floor heating controller 9
Insert into the connection holes 25 of A and 9B.

When the trial run switch 15 of the heat source unit 2 is turned on in the above state, the microcomputer 1 of the heat source unit 2 is turned on.
4 executes a trial run process based on the trial run program shown in FIG. That is, the heat source device 2 transmits the transition data to the “trial operation mode” to the floor heating controllers 9A and 9B by turning on the trial operation switch 15. When the floor heating controllers 9A and 9B receive the transition data to the "test operation mode", the operation lamp 18 and the program operation lamp 22 are blinked regardless of whether the operation is in normal operation or not, and the test driver is instructed to do so. Notify the shift to the "trial run mode".

At the time of shifting to the "trial operation mode", the floor temperature detected by the temperature detector 32 of the temperature detecting device 28 is stored as "T1" data, and whether the floor temperature rises during the trial operation of another system. Determine whether or not. As a result, if the floor temperature rises, erroneous piping or erroneous wiring may be considered. Therefore, "abnormality data" is immediately transmitted to the heat source unit 2 to cause the heat source unit 2 to recognize the occurrence of an abnormality and its contents. It is also possible to provide the heat source device 2 with a 7-segment abnormality code display section and display the content of the code when an abnormality occurs so that the test driver can easily determine the cause of the abnormality.

The heat source unit 2 has the above-mentioned "test operation mode".
When the operation shifts to, first, the circulation pump 3 is driven to fill the pipes 4 and 4 of each heating system with the heating circulating water.
The operation is sequentially switched for each system. And
When the "water filling" on the floor heating radiators 5A, 5B, etc. is normally completed, the floor heating controllers 9A, 9B are made to sequentially perform trial operation.

The test operation by the floor heating controllers 9A and 9B will be described below. The heat source device 2 transmits "test operation mode + filling completion + operation ON" data to the floor heating controller 9A corresponding to the floor heating radiator 5A. Further, the circulation pump 3 is driven to start the normal heating and combustion operation.

Here, the floor heating controller 9A is
At the first reception of the data of “test operation mode + water filling completion + operation ON”, the current floor temperature detected by the temperature detector 32 of the temperature detection member 28 is stored as “T2”. Thereafter, the floor temperature detected by the temperature detector 32 is “T2” + 5d.
The microcomputer 26 of the floor heating controller 9A before the trial operation time limit (for example, 50 minutes) as a predetermined time to determine whether or not the temperature has risen to eg has elapsed.
The test drive pass / fail judgment means 26A provided in the above section makes the judgment.

The above-mentioned trial run time limit is displayed by using the "minute digit" of the program time display section during the trial run, and these are set by operating the temperature increase key 23 and temperature decrease key 24 for changing the set temperature. The temperature increasing key 23 and the temperature decreasing key 24 are also used as changing means, and for example, 20 to 60
It can be changed within the time range of minutes. Therefore, the trial run time limit can be changed according to the installation status of the floor heating radiators 5A and 5B. Further, since the trial run time limit is configured to display the remaining time as the trial run time elapses, the progress of the trial run and the remaining time can be easily determined.

When the test run is normal, the temperature detector 32
When the floor temperature due to the detection of “T2” +5 deg rises, the floor heating controller 9A transmits “test operation normal end” data to the heat source unit 2 and ends the trial operation of the floor heating radiator 5A. Here, when the heat source device 2 receives the "completion of normal operation of trial operation" data, it sends a signal instructing the trial operation of the next floor heating radiator 5B to the floor heating controller 9B corresponding to this floor heating radiator 5B, As described above, the trial run is performed sequentially.

On the other hand, if the bed temperature detected by the temperature detector 32 does not rise to "T2" +5 deg even after the trial run limit time (for example, 50 minutes) has elapsed after the start of the trial run, the trial run pass / fail judgment means 26A Is determined to be incorrect piping or incorrect wiring, and the floor heating controller 9A transmits "test operation abnormality" data to the heat source unit 2. When the heat source device 2 receives the "test operation abnormality" data, the test operation of the floor heating radiator 5A is stopped, and a signal instructing the test operation of the next floor heating radiator 5B is transmitted to the floor heating controller 9B, and Perform a test run as you did.

Further, in the case of performing the trial run again for various reasons, when it is desired to omit the trial run of the system which has already completed the trial run, and when it is desired to clearly know that the trial run has been completed, the test is passed in the "test run mode". By operating the operation key 17 that also serves as the determination key, the floor heating controller 9A determines that the "test operation has ended normally" and transmits this data to the heat source device 2.

Although the test operation of the hot water heating apparatus 1 has been described in detail, each operation mode state during the test operation is displayed by using the "hour digit" of the program display section of the floor heating controllers 9A and 9B. . With such a display, the test driver can grasp the test driving status at a glance. For example, as shown below, each operation mode during the trial operation is displayed by numbers or symbols. FIG. 6 shows an example in which each mode in that case is displayed with symbols (A, b, C, d, E).

A = “test run mode + water filling + operation OFF” b = “test run mode + water fill completion + run OFF” C = “test run mode + water fill completion + run ON” d = “test run mode + test run normal” End ”E =“ Trial run mode + Abnormal end of trial run ”According to the present embodiment, the temperature detecting device 28 includes a plate-shaped heat insulating material 29 made of expanded polystyrene having a thickness of about 6 to 10 mm, and this heat insulating material. A temperature detector 32 with a built-in thermistor disposed substantially in the center of the lower surface of the heat insulating material 29 via a heat equalizing plate 31 made of an aluminum sheet attached to the lower surface of the material 29.
And a lead wire 34 having a desired length, one end of which is connected to the temperature detector 32 and the other end of which is provided with a connection plug 33 which is inserted into the connection hole 25 of the floor heating controller 9A, 9B. And a covering member 35 made of an aluminum sheet attached to the soaking plate 31 so as to cover the surface of the temperature detector 32. 5B, and the lead wire 34 is attached to each floor heating controller 9A, 9A.
Can be set just by connecting to B, floor heating radiators 5A, 5
Not only can the temperature detection device 28 be easily set to B, but the temperature detector 32 can be used for the floor heating radiators 5A, 5A and 5B.
Insulation material 2 is affected by the temperature of the room air in which B is laid.
The temperature of the heating radiators 5A and 5B in a relatively wide range can be suppressed by the coating material 35 made of an aluminum sheet attached to the soaking plate 31 so as to cover the temperature detector 32. 32, and the surface temperatures of the floor heating radiators 5A and 5B can be detected with high accuracy.

A cushion heat insulating material 29A made of felt with the central portion removed is provided on the outer periphery of the cushion heat insulating material 29A, and the cushion heat insulating material 29A is attached to the lower surface of the heat equalizing plate 31. By this, while suppressing the heat radiation from the heat equalizing plate 31, it is possible to prevent a gap from being generated between the surface of the floor heating radiator 5A and the heat equalizing plate 31, so that the temperature detector 32 can prevent the influence of the indoor air. You can avoid receiving it even more.

Further, since a container 30 (weight) made up of a poly tank for accommodating about 1 to 2 liters of a liquid such as water is provided on the heat insulating material 29, the container 30 is accommodated. The weight of the liquid such as water can be stably placed on the floor heating radiators 5A and 5B without the need for the test driver to manually support the temperature detecting device 28 due to the weight of the liquid. Since 32 is pressed against the floor heating radiators 5A and 5B by the weight of the liquid such as water contained in the container 30, the surface temperature of the floor heating radiators 5A and 5B can be detected more reliably.

Further, since the container 30 has an opening / closing lid 36 for opening / closing the container opening and is configured to accommodate a liquid such as water so that it can be taken in and out, the container 30 can be emptied when carrying it away or when not in use. By doing so, it is lightweight and easy to handle.

Further, in the above-described embodiment, since the container 30 is integrally provided with the handle 37, the handle 37 can be carried while being carried, and the usability can be improved. Further, since the container 30 is a resin tank, it is very lightweight when empty and there is no risk of rust, and a commercially available resin tank can be used.
