NOTE:
(1) In parameter setting status, the system runs under original parameters;
(2) Under Constant Temperature control mode (“ F4” and “F8” set at 0), water
temperature is controlled by “F1” and “F5”;
(3) Under Intelligent Control mode (“ F4” and “F8” set at 1), water temperature
is self-adjusting according to ambient temperature. The temperature
difference is controlled by “F2” and “F6”.
(4) The low temp section and high temp section of the chiller can be set
different control modes.
3. Failure warning processing mode
When alarm occurs, the failure alarm code will be displayed on the upper right
corner of the LCD screen. In alarming state, the alarm sound could be
suspended by pressing any button, but the alarm display remains until the
alarm condition is eliminated.
