temperature is controlled by "F1" and "F5";
(3) Under Intelligent Control mode (" F4" and "F8" set at 1), water temperature
is self-adjusting according to ambient temperature. The temperature difference
is controlled by "F2" and "F6"
(4) The low temp section and high temp section of the chiller can be set
different control modes.
