1、 Product Overview
BR-FM01 seriesIntelligent heating control valveIt is a LCD temperature controller mainly used for water heating systems. combineUltrasonic Heat meterThe use can achieve billing (prepaid) heating goals. This product has exquisite design, reliable performance, and simple operation. Using a microprocessor and artificial intelligence fuzzy logic control, the ambient temperature is displayed on the LCD screen at a glance. By setting the required temperature for the room, the controller automatically opens or closes the valve to regulate the room temperature and make life more comfortable.
2、 Working principle
Based on the policy of charging by area for centralized heating, the charging price per unit time per unit area (unit price) is determined based on the charging price and the actual heating time of a heating season. Users purchase heat (time) at this price, and the heating intelligent control valve (hereinafter referred to as the heating control valve) calculates the heat cost based on the user's actual heating area, unit price, and heating time, and deducts it from the purchase quantity. When the purchase quantity is exhausted (zero), heating is stopped, and users need to pay again to purchase heat before continuing to use it, thus achieving the purpose of heat charging management.

4、 Main functions
1. Prepaid management
Prepaid mode, which means buying heat first and then using it: the initial available heat (time) of the heating control valve is zero, and the valve is closed. After opening an account and purchasing heat (time) at the sales hotspot, the user will receive a user card, input the data in the card into the heating control valve, and then open the valve to provide normal heating. After the available heat (time) in the heating control valve is used up, the valve closes, and the user holds a card to purchase heat from the hot spot and inputs it into the heating control valve to continue using heat.
2. Heating and cooling fee control
It is suitable for both centralized heating fee management and control, as well as central air conditioning system fee management and control.
3. Card replacement, recycling and transfer functions
The user card can only successfully transact with the corresponding heating control valve once for each purchase of heat. If the user card is lost, it can be replenished according to the database management function of the charging management system software, and the purchase quantity will not be lost or duplicated. When the heating control valve needs to be replaced, a data recovery transfer card can be used to transfer the data and information in the table to the new table, without affecting the user's card usage operation.
4. Fault valve closing alarm prompt
Equipped with a self checking function for operational status, it automatically closes valves and provides alarm prompts in case of clock, battery, card operation, and other malfunctions. It also provides an alarm prompt for insufficient remaining inventory, ensuring safety and reliability, and preventing damage.
