Operating procedure of the present invention is:

1. The operating procedure of the solenoid valve in working condition is:

1. Shutdown state: The LED color screen displays the clock, hot water temperature, and indoor temperature. All heating equipment is turned off. When the hot water temperature is detected to be lower than or equal to 5 degrees, the system will perform the antifreeze function, and the system will work forcibly. First, start the circulation pump 10 Seconds later, start the first gear power again, stop heating and stop the circulation pump after the temperature of the hot water reaches 15 degrees. (There must be water, no load can be started when there is no water)

2. When the system is turned on for the first time, the system works at the default set temperature (hot water temperature is 60 degrees, indoor temperature is 16 degrees), the system defaults to "winter" and lights up. The power is 7 gears, and the heating strips on both sides are lit. When the hot water temperature reaches 60 degrees, the circulating water pump system is started. When the indoor temperature reaches the set temperature, the circulating water pump system and the heating load are turned off. When the water temperature is lower than 35 degrees, turn off the circulating water pump system. (Water must be available to start the water pump and heating load), and then start up and run at the customer's set temperature. Every time the system is turned on, it works for 7 levels of power.

3. Start the circulating water pump system: the first start: the hot water temperature reaches the set temperature, and the indoor temperature is lower than the set temperature; the second start: the hot water temperature is greater than 30 degrees, and the indoor temperature is lower than the set temperature. The word "Water Pump" lights up.

4. Turn off the circulating water pump system: the temperature of hot water is less than 30 degrees, and the indoor temperature is greater than or equal to the set temperature. The word "water pump" goes out

5. Start the heating load (heating state): the temperature of the hot water is lower than the set temperature, and the indoor temperature is lower than the set temperature. The word "heating" lights up, and the light bars on both sides flash.

6. Turn off the heating load (heat preservation state): the temperature of hot water is greater than or equal to the set temperature; or the indoor temperature is greater than or equal to the set temperature. The word "heating" is off, the word "keep warm" is on, and the light bars on both sides are always on.

7. Reheating: The hot water temperature is less than or equal to 13 degrees of the set temperature of the hot water, and the indoor temperature is less than or equal to 2 degrees of the set indoor temperature.

8. Automatic frequency conversion: After setting the indoor temperature, if the system reaches the set indoor temperature within 40 minutes (less than or equal to 40 minutes), the power of the system will be automatically reduced by one level when reheating next time, so as to By analogy, until it is reduced to the first gear; when the system reaches the set indoor temperature after 40 minutes (more than 40 minutes), the power of the system will automatically increase to the next gear when it is reheated next time, and so on, until it reaches the set temperature. 7th gear.

9. When the user switches from "winter" to "summer", the system enters the domestic water function. (Heating function in winter)

10. Domestic water function: The default hot water temperature of the system is set to 80 degrees, and it runs at full power. (Temperature and power are fixed), the water pump does not turn, it has nothing to do with the indoor temperature. When the hot water temperature reaches 80 degrees, it enters the heat preservation state, and when the temperature is less than or equal to 67 degrees, it runs at full power to 80 degrees, and so on. Not related to timing functions.

11. In the "winter" state, when the water flow switch is closed for 40 seconds, the system also enters the domestic water function. After entering, when the water flow switch is turned off for 3 minutes, it returns to the winter heating function.

12. Water shortage state: When the system detects that there is no water, the word "water shortage" will light up, and when there is water, the word "water shortage" will be off.

13. Timing state: the system controls the heating equipment according to the set temperature value, but works within the time period defined by the user. There are three timing periods. The default on and off time is 00:00. When the on and off times are the same, it means that the timing period should be skipped. After setting the time, press and hold the "Function" key for 3 seconds continuously to enter the timing state, and press the "Function" key for 3 seconds continuously to exit the timing state. Or shutdown can also exit the timing function.

14. External device function: When the external connection selection port is at low level, the system enters the external device function. At this time, the original indoor temperature probe is invalid (the probe can be unplugged at this time), and the set indoor temperature is also invalid, but Whether the indoor temperature has been reached is judged by the external signal port. If the external signal port is high level, it means that the indoor temperature has been reached (operate according to the original function of the indoor temperature reached), and if the external signal port is low level, it means The indoor temperature has not been reached (operate according to the original function that the indoor temperature has not been reached). When the domestic water function is used, the external signal port does not work.

15. Power-off memory: When the system is powered off, all set parameters, heating and timing status will be memorized, and faults will not be memorized.

2. The one-button energy-saving operation procedure of peak and valley electricity is as follows:

Continuously press the "minus" button for 3 seconds, the system enters the one-button energy-saving program state of peak and valley electricity, at this time, the icon of "timer 3" is flashing, and the default time of peak and valley electricity timing is 23:01. Cooperate with "Add", "Subtract" and "Function" to adjust the default time of peak and valley electricity timing to be on at 23:01, and the default time of peak and valley electricity timing to be off at 06:58, (to prevent peak and valley electricity in some places The electricity time is different). After the time is set for 5 seconds, confirm and enter the one-button energy-saving program of peak and valley electricity. When Beijing time reaches 23:01, turn off solenoid valve 1, turn on solenoid valve 2, turn on water pump 1, and start heating. Control (no matter how many degrees are ignored), the default temperature of the hot water setting is 80 degrees, when the bucket temperature sensor detects that the water temperature is 80 degrees, stop heating (when the bucket temperature sensor is faulty, the system can still work normally, at this time Take the hot water temperature sensor of the heating water tank as the standard), when the temperature drops to 70 degrees and then reheats to 80 degrees, when Beijing time reaches 03:00, regardless of the temperature of the bucket, the heating will stop, but the water pump 1 is still working ;When Beijing time reaches 03:10, close the solenoid valve 2 and open the solenoid valve 1. At this time, the default temperature of the hot water setting is 75 degrees, and the default temperature of the indoor setting is 27 degrees. This working state has been working until 06:58 Beijing time , then close the solenoid valve 1, close the solenoid valve 2, and turn off the water pump 1. When the indoor temperature drops to 16 degrees, turn on the water pump 2 and let the indoor temperature reach 20 degrees. When the hot water (detected by the bucket temperature sensor) is lower than 28 degrees, and the indoor temperature is lower than 18 degrees, it will automatically return to the original setting program before the peak and valley electricity one-button energy-saving program state, and turn off the water pump 2 at the same time , turn on the solenoid valve 1, work like this for one day, and enter the state of the peak-valley one-button energy-saving program at 23:01 the next day, and work in a cycle like this, then press the "function" button for 3 seconds continuously, if you want to cancel In the state of the one-button energy-saving program of peak and valley electricity, just press the "minus" button for 3 seconds continuously.
