Case 1: The cooling water temperature is controlled by the intelligent mode. The required
water temperature is from 25
℃
to 31
℃
and the set water temperature is 3
℃
lower than
the room temperature. Under the condition of constant room temperature, the fluctuation
should not exceed ±0.5
℃
. (e.g., There will be an alarm when the water temperature is
15
℃
lower or higher than the target temperature. If the room temperature is 30.0
℃
,
cooling water temperature is between 27.5
℃
to 26.5
℃
, if the air temperature is up to
30.5
℃
, water temperature will be between 28.0
℃
to 27.0
℃
).
Case 2: The cooling water temperature is controlled by the constant mode. It is required
that the water temperature is kept constant at 25
℃
, and the fluctuation should not
exceed ±2
℃
. There will be an ultra-high water temperature alarm when the water
temperature is 5
℃
higher than the target temperature; and there will be an ultra-low
temperature alarm when the water temperature is 10
℃
lower than the target temperature.
The water temperature setting can be easily adjusted from 5
℃
to 30
℃
s by user setting.
VI. Alarm & Output Terminal
In order to guarantee that the equipment will not be affected if abnormal situation happens
to the chillers, the chillers has been designed with an alarm protection function.
