SR981S/SR982S operation manual of solar pump station
Page 29 of 85
System 10: 1 tank + T-valve controlled by return heating
Description:
Controller compares the temperature between T1 of collector array and T2 of tank, when
temperature difference reaches its switch-on value (DT1O), then P1 is triggered, tank is
heated until tank temperature reaches its maximum value or when temperature difference
(DT1F) drops to the switch-off value, then P1 is ceased.
Another temperature difference between T4 and T6 (DT2O/DT2F) to control T-valve R1 to
heat the heating return by solar.
Note: when T4 is not installed, then temperature difference between T3, T6 ( DT2O/DT2F)
is used to control T-valve R1
When T3, T4 are not installed, then temperature difference between T2, T6 ( DT2O/DT2F)
is used to control T-valve R1
See detailed in 8.4.8/8.4.9
