General parameters
The parameters of the industrial chiller supplied with the ENERGY machines are preset
(Initial setup). It is not necessary to change these parameters.
Press the (SET) button in normal mode. The red indicator light flashes. This indicates that the controller is in
parameter setting mode.
• In constant temperature control mode, the screen displays the value of the set temperature (parameter
F0).
•
In intelligent control mode, the screen displays the temperature difference between that of the water and
that of the ambient air (parameter F1).
Use the arrow keys to change the parameters.
After modifying the values, press the (RST) button to save and exit. The new parameters become active.
Otherwise, press the (SET) button to exit setting mode without saving the new parameters.
If no button is pressed within 20 second(s), the controller automatically exits parameter setting mode
without saving the modified parameters.
