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
5
℃
higher than normal, and the alarm of over low water temperature will be on
when water temperature is 10
℃
lower
than normal.

)
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
℃
)

Flow alarm and output ports
In order to guarantee the equipment will not be damaged while cooling water circulation is out of
control, WJ-5000/5200series chillers possesses an unique low flow alarm protection.
