If r is set, for example, when the room temperature drops significantly from the set value and the resistance value of the room temperature sensor 4 made of a thermistor increases significantly, the current flowing through each resistor 18H and 118L becomes smaller, and the current flowing through each resistor 18H and 18L decreases. The voltage generated will also be lower. At this time, if the heavy pressure generated in the high temperature detection resistor 1BH is, for example, 2V, and the voltage generated in the low temperature detection resistor 18L is, for example, 1.9V, then the corresponding high temperature discrimination comparator 20H and low temperature discrimination Each of comparators 20L and 20K is applied as a negative input. The high temperature discrimination manno e-lator 20H compares the positive human power of 3V with the negative input of 2V, and since the difference is +1■, it outputs a high temperature control signal (H).

This resistor is more sensitive than the state, and these resistors 1
The voltages generated at 8H and 18L are also higher than in the previous state.

At this time, the sieve detection resistor 18HVC is generated.
If the voltage is, for example, 3, IV, and the voltages generated in the low temperature detection resistor 18L are (1-1, 2, 9), then these correspond to the high-temperature r utilization comparator 20H and the low-temperature discrimination con/9 rake 20. .L and are respectively applied as negative inputs.

When the room temperature rises further and reaches the ° set value, the high temperature discrimination comparator, F regulator 20H, and low temperature discrimination comparator 20L are activated.
Control signals are no longer output from any of the above.

It operates in the same way when there is a change in floor temperature.

In the above embodiment, control is performed using the relays 12H and 12L, but it is also possible to directly control the electronic control circuit for controlling the DCee burner using the control output of the receiving side discrimination control circuit 14.

Further, in the above embodiment, the present invention was applied to a remote temperature control device for hot water floor heating, but the present invention is not limited to this, and can be similarly applied to various remote control devices. be.

For example, it can be applied to a remote liquid level control device for liquid supply as follows. In other words, the liquid level in the tank during liquid supply is detected by multiple sensors of a sensor-equipped transmitter, and the detected contents are converted into voltage signals with different levels, which are sent to the control receiver side using a 2-core control cable, and then By distinguishing the voltage level, controlling the opening of the liquid supply valve according to the paper pressure level, and reducing the opening of the liquid supply valve when the liquid level approaches the target level, waves on the liquid level can be reduced.

Resistors 8A and 8B are connected in a circular manner between 3B and 7, a switching element 9L is connected in series to the series circuit of the resistors 8A and 8B, and a switching cable 9Hi is connected in parallel to the resistor 8B and switching element 9L. The control section and pressure signal generator 1o having such a structure can also be operated in the same manner. In this case, the resistance value of the first rsl resistor 8H is RH1, and the resistance value of the resistor 8L is RL, and the resistance value of the resistor 8H of the first rsl is 1.

The reason for the pressure level is that the pressure level is discriminated and the control level 1 is output according to that level to perform the wholesale jump 1, so it is also possible to perform a multi-stage crawl. Regarding the connection between the 8 sensor material feeders and the control tube, the control cable only needs to have 2 cores, which prevents the wiring from overflowing, and prevents the wiring from being connected to the home, which also reduces costs. However, in the present invention, a common IJ source can be used on the transmitting side and the receiving side, and there is no need to secure a full power supply on the transmitting side, so it is very effective in implementation.
