Electric water heater PCBA
1. instant heating / thermal insulation: heating to the set temperature that is disconnected from the power supply into the heat insulation state, in the heat preservation state, when the water temperature drops 8.
2. water temperature display: display the measured temperature and set temperature.
3. temperature settings: set the highest heating water temperature (30~75 degrees C).
4. appointment: (1) the timing of the boot: in the setting time to enter the heating / thermal insulation; (2) the timing shutdown: in the setting time to exit the heating / thermal insulation.
5. night power: the system by default in the night from 0 to 6 in the early morning heating / thermal insulation, but also can be arbitrarily set the night time period.
6.energy saving heating to 50 degrees centigrade, the water temperature is less than or equal to 45 DEG C and automatically heated to 50 DEG C.
7. over temperature protection: when the hot water temperature rises to 90 degrees Celsius, immediately cut off the power supply of the electric heating tube.
8. sensor fault protection.
9. leakage protection.
10. dry burning protection.
11. clock display.
