What is the appropriate temperature setting for solar water temperature control? Is there a difference between summer and winter?
Water supply and heating are automatically controlled according to the sun's schedule. When the water is not full, when the sun rises (the temperature rises by 6℃), the water will automatically start to the preset water level. At about noon, when the water in the water tank is not full and the water temperature is higher than 70℃ and higher than the preset temperature 15℃, the temperature-controlled water replenishment will be started, and it will stop when the water replenishment is higher than the preset temperature of 5℃.
When the sun goes down (the temperature drops by 3℃), the temperature will no longer rise. If the temperature of the water tank is lower than the preset temperature, start heating to the preset temperature. If it is cloudy today (no sun), water supply and heating shall be carried out respectively according to the time of water supply and heating yesterday.
The preset heating temperature range: 30℃-80℃. At this time, manual start or automatic start heating will stop at the preset temperature. If it is set to 00℃, it means that the automatic heating function is cancelled. At this time, heating was started manually, and stopped at 50℃.
Extended data
Temperature-controlled water supply is the function of using temperature controller to control water supply in cold water.
The principle is as follows: all the control circuits of solar water heater are integrated on a circuit board, which has the functions of temperature control and heating. The function of this function is to ensure that the water in the water tank will never be lower than the set temperature (for example, bath water, the water temperature is set at 45℃).
1. When the water level of the water tank has reached the full level, no matter how many degrees the water tank is, it will not be filled with water at this time.
2. In the process of water supply, when the solar energy is short of water, the sensor senses the water shortage state and sends a signal to the intelligent instrument. After receiving the signal, the intelligent instrument gives the solenoid valve a voltage of 12V, and the solenoid valve automatically opens. The process of self-feeding water is completed under the condition of water shortage.
3. When the water is full, it stops automatically, and the same sensor sends a signal to the intelligent instrument. When the intelligent instrument receives the full water signal, close the solenoid valve (12V), and the solenoid valve will automatically close. The process of automatic stop is completed when the water is full.
