intelligent Solar Controller for solar water heater (SR728C)

6. Heating function: Electrical booster timing heating: Within 24 hours three pre-set time sections can be set, when the pre- set time comes, heating starts. When tank temperature is 5º C lower than the set temperature, electrical booster is triggered and heat water to the setting temperature.

5. Instantaneous circulation: Inorder to achieve the immediately hot water using, it is possible to start pipe circulation pump at any time. Working process: Pump operates for 3 minutes, and then stops automatically.

4.3. Operation principle withn the set time sections: During the set timesection, pumps works for three minutes, then stops for 15 minutes, ame process sontinues so.

4.2. The three time sections can be adjusted at will. Adjustable range: 00: 00-23: 50

This controller is possible to achieve timing hot water circulation within a day, three time sections can be set to trigger pump. The first timing section: Default 6: 00-8: 00. The second timing section: Default 10: 00-10: 00. Default is not working at this section. The third timing section: Default 19: 00-21: 00.

4.1. Timing circulation

4. Hot water circulation pump:

3.2. When the temperature difference between collector and water tank drops below the switch-off temperature difference, then solar circuir prmp stops. Adjustable switch-off temperature difference is 1-10K, default value is 5K.

3.1. When the temperature difference between the collector (T2)and the tank (T3) is exceeded the swich-on temperature difference, solar circuit pump is triggered to transfer heat from collector to tank; The adjustable range of switch-on temperature difference is 2-15K, default value is 10K.

3. Temperature difference controlled solar circulation pump:

2. Indicating of water temperature: Display actual water temperature at solar collector and at water tank.

1. Clock: Display 24 hours clock time.

Main Functions:

1. Display dimension: 495mm x 170mm x 65mm
2. Power supplier: AC220V
3. Accuracy of temperature measuring: 2
