Zhejiang EAMMAR Solar Energy Co., Ltd

 Working Station

Main functions:

1.Display water temperature of tank and clock time

2.Temperature difference controlling function

Set switch-on and switch-off temperature difference. When the preset temperature difference between collector and tank is reached the switch-on temperature difference, pump is switched on, and stopped when reached switch-off temperature.

3.Temperature controlled auxiliary heating during three time sections

During the preset time sections electrical booster is triggered when the temperature of top part of tank is 6C below the preset temperature of electrical booster. When temperature exceeds or equals the preset temperature, electrical boost stops heating.

4.Time controlled hot water pipe circulation

During the preset time sections the circulation pump is triggered automatically.

5.Temperature controlled hot water pipe circulation

When the temperature signal of sensor is less than the preset turning on temperature, the hot water circulation pump is triggered and works till the temperature exceeds the turning off temperature.

6.Anti freezing protection of collector

In winter when the temperature of collector is below the preset start temperature of anti-freezing protection, solar circuit pump is triggered.

7.High temperature protection function of tank

In order to avoid the high temperature of tank, controller will check the temperature of top part of tank, when it rises to set temperature, this function is activated, and solar pump is ceased. When temperature of top part of tanks drops less than set temperature, this function is deactivated automatically.

8.Protection function:

Memory protection: in case power failure occurs, controller keeps the parameter settings unchanged.

Screen protection: when no any press on button for 30 minutes, screen protection is activated, and then LED light lamp is switched-off. Through press any button to light LED lamp again.

System comeback: when mistakes or problems occur in system, press "OK"button, which is on display panel, to recover system to factory set.
