Abstract

PURPOSE:To keep an insulation distance between a heavy electric circuit and a light electric circuit by a method wherein a terminal part to which an AC source is inputted, a terminal part to which a low signal from a sensor is inputted, a terminal part connected directly to a heating device, and a terminal part on which a low signal for controlling a relay is applied are arranged in a specified position relation. CONSTITUTION:A terminal part 1 to which an AC source is connected is located on one side of the back of a controller body, and a terminal part 2 to which a signal conductor from a sensor S is connected is located on the other side. A terminal part 3 to which a line source is connected for directly controlling a floor heating panel is located on the terminal part 1 side between the two terminal parts 1 and 2, and a terminal part 4 connected to a relay box is located on the terminal part 2 side. When a floor heating controller and a floor heating panel are directly controlled, a floor heating panel is connected to the terminal part 3. A distance between the terminal part 3 of a heavy electric circuit and the terminal circuit 2 of a light electric circuit is increased to a high value in a way that the terminal part 4 for a relay box and a valve forms an empty terminal. When a relay box is used, the insulating distance can be increased to a high value in a way that the terminal part 3 forms an empty terminal.

[Function 1] Therefore, when using the third terminal part, the insulation distance between the third terminal part of the strong current circuit and the second terminal part of the weak current circuit is set as the fourth terminal part is vacant. and also the 4th
When using the terminal section, the third terminal section is left as an empty terminal to ensure an insulating distance between the first terminal section of the heavy current circuit and the fourth terminal section of the weak current circuit.

[Example 1] Below, an example of the present invention will be described with reference to the drawings. Floor heating systems include an electric type shown in FIGS. 4 and 5, and a hot water type shown in FIG. 6. For example, the electric floor heating system shown in FIG. 4 includes a floor heating panel B installed on the floor and a floor heating controller A that controls the operation of the floor heating panel B. Controls energization of the heater built into the floor heating panel B according to the operation of the operation unit or timer settings, and sets the temperature of the floor heating panel B based on the output from the sensor S built into the floor heating panel B. Keep at temperature
). If the wattage of the floor heating spring B is high, the energization to the heater is controlled via the relay hose C as shown in FIG. At this time, the floor heating controller A and the relay box C are connected to the low-voltage light power wiring for controlling the relay coil, and the AClooV is connected to the floor heating panel B via the relay box C.

In addition, in a hot water type floor heating system, as shown in Fig. 6, for example, hot water supplied from a heating boiler D is circulated in a pipe E buried in the floor surface to perform floor heating. The heating controller A controls the drive of the heating boiler D according to the output of a sensor S installed on the floor, and controls the circulation of hot water in the pipe E by controlling the opening and closing of a valve (e.g., a thermal valve) F provided in the pipe E. to control the floor heating temperature to the set temperature. Here, the floor heating controller A is provided with a home automation device (HA>N) conforming to the JEM1436 standard so that it can be incorporated into a 5HA system.

Figure 1 shows the back side of the controller main body, where one side is provided with a terminal section 1 to which an AC 100V AC power source is connected, and the other side is connected to a signal line for small signals from the sensor S. A terminal portion 2 is provided. Further, between both terminal parts 1.2, a terminal part 3 is provided on the terminal part 1 side to which a power line is connected in order to directly control the floor heating panel B, and on the terminal part 2 side, A terminal section 4 is provided for connection to a relay box for small signals. Here, terminal section 1

Figure 2 shows a case where the floor heating controller A is used to directly control the floor heating panel B. In this case, the floor heating panel B is connected to the terminal section 3, and the terminal section 4 for the relay box and valve is connected. This is an empty terminal. Therefore, by leaving the terminal part 4 as an empty terminal, it is possible to increase the distance between the terminal part 3 of the strong electric circuit and the terminal part 2 of the weak electric circuit, thereby increasing the insulation distance.

Figure 3 shows the case where the beam is connected to the terminal section 4. Connect the relay box to terminal section 4. Terminal section 3T! : It's an empty terminal and Chichino. Therefore, in this case, the terminal section 1 of the high-voltage circuit

A third terminal part to which a strong electric current is applied and which is directly connected to the heating device is provided on the first terminal part side, and a fourth terminal part to which a small signal for controlling the relay in the relay box is applied. Since the terminal part is provided on the second terminal part side, when the 3f) terminal part is used, the fourth terminal part is used as an empty terminal and the third terminal part of the strong current circuit and the third terminal part of the weak current circuit are used. 2nd G) It is possible to secure the insulation distance with the terminal part, and when the 4th terminal part is used, the 3rd terminal part can be used as an empty terminal to connect the 1st terminal part of the strong current circuit with the weak current terminal part.
