Scope

Main Technical Content: 6.2.1 Basic Functions 6.2.1.1 Display Function 6.2.1.1.1 Time Display and Time Control Accuracy: If the system controller has time display and control functions, the allowable time accuracy is 1 second. 6.2.1.1.2 Temperature Display and Error: The maximum temperature display resolution is 1°C, and the displayed value should be stable. The display accuracy of the collector temperature is 1°C. The temperature of the storage water tank within the range of 0°C to 100°C should have a display accuracy of 1°C. 6.2.1.1.3 Water Level Display and Error: The water level display should at least include the low water level and full water level, and the display should be stable. For systems with segmented water level display, the display accuracy under full-scale conditions should not be less than 5% of the nominal height; for systems with continuous water level display, the display accuracy should not be less than 5%. 6.2.1.2 Control Functions 6.2.1.2.1 Temperature Control: When the system controller starts the auxiliary electric heater to heat the water in the storage tank to the set temperature, the auxiliary electric heater should stop heating. If the controller has a circulating heat exchange function, the circulating heat exchange function should stop working when the system reaches the stop temperature. 6.2.1.2.2 Water Level Control: After the system controller starts the control valve to supply water to the set water level, the controller should close it. 6.2.1.2.3 Circulating Heat Exchange Function: In forced circulating separation solar water heating systems, the system controller should have an automatic control circulating heat exchange function. 6.2.1.2.4 Leakage Protection: The system controller should have a leakage protection device, and the operating current should comply with the provisions of GB 13955. After the leakage protection action condition is met, the power supply of the leakage protection device should be com
