7.7 Dynamic setpoint function
The regulator allows the operating setpoint to be modified by adding or subtracting a coefficient proportional to the external
air temperature.
For industrial applications, the purpose of this function is to prevent condensate from forming on the surface of the
component cooled by the unit.
The operating setpoint increases proportionally as the ambient temperature rises; the difference between the ambient
temperature and the operating setpoint is a value which can be set by means of parameter Sd03, with values from 23 ÷ 41°F.
To activate the function, set the following parameters:
Chiller setpoint ST01= 32°F
Max. increase in dynamic setpoint Sd01= 86°F
Temperature differential between external air and dynamic setpoint Sd05= 54°F
External air temperature - dynamic setpoint delta Sd03= 23 to 41°F
The graphs below illustrate operation of the dynamic setpoint (SEtr) with Sd03 set at 39°F and 25°F.
For example, with ambient T of 75°F the operating setpoint SEtr= 68°F in case 1 and SEtr= 82°Fcase 2.
Case 1 - Sd03= 39
Case 2 - Sd03= 25
