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
℃
).
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 7
℃
(F4+F2) higher
than normal, and the alarm of over low water temperature will be on when water
temperature is 12
℃
(F5+F2) lower than normal.
VI. Alarm & Output Terminal
In order to guarantee the equipment will not be affected while abnormal situation
happens to the chillers, the chillers are designed with alarm protection function.
