1. Usage environment of IC card water controllers: Any location with tap water flow can utilize the controller to achieve water-saving purposes. For example: bathrooms, collective and individual apartments, water boiler rooms, etc. The product design fully considers performance aspects such as waterproofing, safety, practicality, and operability.

2. Energy-saving method of IC card water controllers: Smart card water-saving devices are mainly used to control solenoid valves and simultaneously achieve billing based on time and flow rate during water usage.

3. Power supply for IC card water controllers: IC card water controllers are uniformly powered by a dedicated power supply cabinet (220V to 12V) in the equipment room or substation. Each transformer can supply power to 20 to 40 IC card water controllers, with a distance requirement of within 500 meters. The water-saving controller and water-saving valve operate at a safe AC voltage of 12V, with no high voltage or 220V AC voltage, ensuring user safety. The solenoid valve uses a low-energy consumption coil to ensure operation at lower current.

4. Waterproof measures for IC card water controllers: The outer shell of the IC card water controller is designed with waterproof materials. The data cable entry and exit points use waterproof connectors. A rubber ring is pressed into the groove at the joint between the bottom cover and the top cover, with the rubber groove designed in a labyrinth style. Wiring requirements should be synchronized with decoration, running lines inside walls for safety. If wall modification is not possible, piping can be used for wiring.

5. Fee settings for IC card water controllers: Each IC card water controller can be individually set with a ratio of water volume to time, converting to a time-based billing mode. A flow rate and time correspondence table is set according to the customer's water pressure and pipe diameter (unit: yuan/minute). Fees can also be set based on flow rate as needed.

6. Main uses of IC card water controllers:

Water room usage—eliminate waste

Bathhouse charging—save water resources and energy in bathrooms.

7. Selection of electric valves: There are many types of electric valves connected to IC card water controllers on the market, but few meet the usage environment. Classified by material, they include plastic, cast iron, cast copper, and stainless steel, all of which must meet basic requirements for waterproofing and safe voltage. Considering different environments for常溫 water and boiling water, different valves are used in bathrooms and water boiler rooms to avoid electric valve blockage caused by scale (or add filters). Selection of electric valves or solenoid valves is considered from five aspects:

Durability: Choose those with a longer lifespan to avoid customer waste and system instability.

Aesthetics: Primarily choose cast copper and stainless steel for aesthetic reasons.

Economy: Consider the large quantity used, reasonable pricing, and reducing operational and maintenance costs.

Safety: Due to high water and steam in general locations, a DC power supply of 12V is required.

Waterproofing: All electric valves provided to customers have waterproof functionality.

II. Software Introduction:

1. Functions such as account inquiry, card issuance, account opening, account closure, loss reporting, loss revocation, card replacement, and subsidies.

2. Powerful business statistical analysis functions, providing daily, weekly, and monthly reports.

3. Automatically identifies the legality of the cardholder's card and decides whether to allow consumption based on the account information in the card. The using unit can set a minimum consumption amount; if below, it cannot be used.

4. Rejects consumption for unregistered or illegal cards and displays prompt information.

5. Features include loss reporting, operator password, administrator password, hierarchical permissions, report anti-counterfeiting, legal error correction,誤操作 recovery and reminders, dual hard drive backup for PC, and USB backup.

6. The water controller enters sleep mode when not in use.

7. The water controller can self-check, with various statuses or faults displayed through self-inspection.

8. Provides prompt information for non-system cards or operational errors.

9. Can control water usage based on time or flow rate.
