7. Advanced parameters adjustment case:
(1) Case 1: cooling water temperature is controlled by intelligent mode. Requiring
water temperature to be between 25℃ to 31℃. Ambient temperature keeping
constant, when the set water temperature is 3℃ lower than the ambient, the
fluctuation will not exceed ± 0.5 ℃ . There will be an alert when water
temperature is 10 ℃ lower or higher than target. (e.g. when ambient
temperature is 30.0℃, cooling water temperature is between 27.5℃ to 26.5℃,
if ambient temperature is up to 30.5℃, water temperature will be between 28.0
℃ to 27.0℃.)
(2) Case 2: cooling water temperature is controlled by constant mode. Requiring
water temperature is constant in 28℃, and the fluctuate does not exceed ±2℃.
The alarm of over high water temperature will be on when water temperature is
5℃ higher than normal, and the alarm of over low water temperature will be on
when water temperature is 10℃ lower than normal.
(3) Case 3: cooling water temperature is controlled by constant mode. Requiring
water temperature is constant in 25℃, and the fluctuate does not exceed ±1℃.
The over high water temperature will be on then water temperature is higher
than 30℃, and the alarm of over low water temperature will be on when water
temperature is lower than 10℃ . (No matter what is the ambient temperature,
the cooling water temperature is constant in 24.0℃ to 26.0℃)
