User’s Manual SP226 Functions and operation Danger: Before connecting the power supply, make sure that the water tank, solar collector, solar pumping station and all temperature sensors are good connected! Note: For safety, auxiliary heating is locked at delivery state. The single “... - Page 9 User’s Manual SP226 Note: Between 60~70℃ scale can form more easily, we usually set the water tank temperature at 60℃. 3.3 Time-controlled circulation function This function needs an extra circulation pump (P2). You can set up a timer program with up to three time periods.
- Page 10 User’s Manual SP226 ì Immediately after setting the first time period, the display enters into the operating menu of next time period. ì Perform like above steps, the other two time periods can be set. Note: If you want to shut off one of the three time periods, you can set a same value for both start time and end time, e.g., you can set both the start and end time of second time period at 10:00 am.
