Page 6: Ⅲ System Description
Work station series for solar water heating control system Ⅲ System description (8 systems available) Danger: If there is only one temperature sensor in water storage (usually in bottom part T2), it is possible, and that the auxiliary heating function will not be activated or deactivated at a right time, because the water temperature in top part of the storage (T3) cannot be measured.
Page 7 Work station series for solar water heating control system 2. System 2: 1 collector array – 2 storage – 2 pumps Description: When switch–on temperature difference between collector array (T1) and one of the storage (T2 or T5) is reached, the solar circuit pump (P1) or (P0) will switched on. According to the priority switching, tw o storages (T2, T5) will be loaded one by one.

Page 9 Work station series for solar water heating control system The solar pump (P1) is switched on as soon as the switch–on temperature difference between one of the two collector arrays (T1, T0) and storage 1 (T2) is reached, the valve R1 is always set so that flow occurs through the warmer of the two collector arrays (T1, T2).
Page 10 Work station series for solar water heating control system 7. System 7: 2 collector arrays – 2 storages – 2 pumps – 1 valve Description: When switch-on temperature difference between one of the two storages (T2, T5) and collector array 1 (T1) or collector array 2 (T0) is exceeded, then the switching valve R2 switched the corresponding collector array (T1 or T0) into the solar circuit.
Page 11 Work station series for solar water heating control system switches relevant storage (T2, or T5) to the solar circuit. Then either solar circuit pump P1 for collector array 1 (T1) or solar circuit pump P0 for collector array 2 (T0) is switch-on, Depending on where the temperature difference occurs.

Page 14 Work station series for solar water heating control system ì Press “Confirm” button to confirm the setting, press “Cancel” button to cancel this setting. ì Immediately after setting the first time period, the display enters into the operating menu of next time period.
Page 15: Frost Protection
Work station series for solar water heating control system Note: When forbid auxiliary heating, customer can’t switch on/off auxiliary heating manually and time-controlled auxiliary heating function is also automatically deactivated. 9. Frost protection In winter, when the temperature of collector drops below the preprogrammed starting temperature of frost protection (default value 5℃), solar pump P1 starts working.

Work station series for solar water heating control system ⅡMounting 1. Open the package carton and take out the solar control system carefully. Determine the mounting position of the solar control system, considering the mounting place for expansion vessel. See picture 1. Picture 1 2.Drill the holes for dowels, put the dowels into the holes, fixed the solar control system on the wall using fastening screws.
Page 21: Ⅲ Electrical Wiring
Work station series for solar water heating control system 4. Determine the mounting place for the expansion vessel. Connect the expansion vessel. See picture5. Picture 5 5. Filling the system ◆ Open the air vent valve. ◆ Open the filling connector (1) and connect a separate pump to the system with pressure hose. The heat medium liquid (usually use water-glycol mixture as heat medium, 50% glycol and 50% water) will be pumped into the system until it overflows through the air vent valve.
