The working principle of the toilet water-saving device
>The toilet water-saving device is composed of an infrared thermal detector, a microcomputer programmable controller and a low-voltage DC solenoid valve. Its working principle is to pass the infrared rays through the human body The work is done by induction. When someone moves in front of the detector, the red light of the detector flashes immediately, indicating that the person has been sensed. At the same time, the detector transmits the induction signal to the microcomputer programmable controller, and the controller controls the solenoid valve to open the water and the water filling time. Can be adjusted freely. When someone comes, the water is released, and no one stops the water. It is especially suitable for trench toilets in schools, shopping malls, factories and other units. It has high water saving efficiency, safety and energy saving. Human body infrared sensor % recognition, can identify objects (clothing) of different colors and materials, with zero leakage rate.

Installation method
>Use screws to fix the microcomputer program controller and infrared detector on the wall. The detector can be installed along the wall or on the ceiling. The probe sensing window needs to be aligned with the toilet bowl or toilet steps.
>Install the solenoid valve on the water inlet pipe. Pay attention to the direction of the water inlet. If there is a filter, connect it to the water inlet pipe, as indicated by the arrow.
>Connect the solenoid valve and infrared detector to the terminal blocks on the microcomputer controller.
>Connect the power supply to the terminal block on the microcomputer controller.

Functional features of toilet water saver
>Automatic induction: fully automatic intelligent control by microcomputer, without direct human contact, which can effectively avoid bacterial cross-infection.
>Digital adjustment: Adjusting program parameters only takes a few seconds.
>High reliability: microcomputer control technology, no batteries required, the program will never be lost under any circumstances, the system is designed according to industrial standards
>Suitable for various harsh environments: whether it is high temperature in summer or more than ten degrees below zero Even in severe cold weather, the product can work normally.
>Safe to use: Install at a height of more than 1 meter to avoid personal contact and avoid human damage.
>Easy to install: no embedded parts in the wall, installation only takes hours.
>High return on investment: water saving rate is %%, and the entire investment can be recovered within ~ months.

Daily maintenance of toilet water saver
>Toilet water saver controls the water control system through a solenoid valve. After long-term use, there will be impurities in the pipes. Generally, clean the water inlet filter once a month. If the water volume becomes small, disassemble the inside of the solenoid valve, clean it first, and then put it back as it is, which can extend the service life of the machine.

Solution to common faults of toilet water-saving devices
>No water comes out if there is a sensor (indicator light is on): Check whether the solenoid valve filter system is blocked by impurities and clean it. And disassemble the solenoid valve, clean the internal components, and then put it back as it is. If the solenoid valve does not work, just put a new solenoid valve coil directly.
>No sensor (indicator light does not light up), water often flows or no water comes out: Check whether the circuit is connected properly and whether there is power supply. If everything is normal, replace the infrared detector.
> If there is normal water flow (indicator light is on): clean the filter and solenoid valve and reinstall them as they are.
Toilet Water Saving Device Installation Instructions
>Trench type public toilet water saving device is to install a solenoid valve on the water inlet pipe of the original automatic water tank and install it in the public toilet stool trough. Or install an infrared sensor on the ceiling at the entrance of the urinal. The infrared sensor automatically detects the scene. When someone enters the public toilet, the infrared sensor sends the detected signal to the control box. The microcomputer in the control box sends out a predetermined program after processing. The command controls the solenoid valve to inject water into the automatic water tank for flushing. If no one enters the public toilet, the entire system will stand still and will never be flushed. In this way, the hygienic and water-saving use effect of unattended, automatic management, flushing when there is someone and stopping when no one is available is achieved.
