4-20 mA Set Point Control

This feature is optional and may not appear in your version of the software.

NOTE:

Two versions are available. If the model number of your Chiller contains an

in the 11

digit (e.g., 6860T56A26

D), it provides 4-20mA set point control over a temperature range of 5° to

90°C; if the 11

digit is an

, the 4-20mA control range is 4° to 40°C

Go to menu item “CC” and set to “YES”.
If current input is outside of the range of the 4–20 mA, “Ft 18” will be displayed.
