1.Solar water heater controller/Solar controller (SR500) LCD display sample available Solar water heater controller Solar Controller SR500 Digital LCD display (CE approved) has a blue background LCD display; It is developed with the newest Sumsun high performance SCM and specially designed for solar system. It possesses nice appearance, reliability and stable performance, and it is easy to install. It is the most ideal device of solar system.

Technical Data:

1. Display dimension: 495mm x 170mm x 65mm

2. Power supplier: AC220V

3. Accuracy of temperature measuring: 2ºC

4. Range of temperature measuring: 0-99ºC

5. Available power of controlled pump: <600W

Main Functions:

1. Clock: Display 24 hours clock time.

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

3. Temperature difference controlled solar circulation pump:  

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.

3.2. 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.

4. Hot water circulation pump:

4.1. Timing circulation

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.

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

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.

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.

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 5 C lower than the set temperature, electrical booster is triggered and heat water to the setting temperature.
