5. General settings adjustment

Press SET key to enter into the user-defined state. Meanwhile, PARAM SET is
on, controller in parameters setup status.

(1) Under intelligent mode, the control panel displays the temperature difference

value between water and air (default value is -2).

(2) Under constant temperature mode

the control panel displays the set

temperature value (default value is 25).

At this moment, press

keys to change settings. After modifying the

value, press RST key to save and exit, then new parameters take effect, or
press SET key to exit without saving parameters. If there is no more action
within 20 seconds, it will automatically exit modifying status without saving
parameters.

6. Advanced settings adjustment

(1) Press and hold the

key while press SET key for 5 seconds until 00

displayed in upper window and PAS in lower window. Then press
keys to select the password (default setting is 8), and then press the SET key, if
the password is correct, F0 displays, entering into setup status, D1 flashing to
indicate that the controller is under parameters setup status. If the password is
incorrect, it returns to temperature display.

(2) Enter setup state, press

keys to switch parameter items

circularly, then press

keys to modify the parameter values. Press

enter key RST at any time to exit parameters setup with saving modified
parameters and return to temperature display, then chiller runs under the new
parameters. If no key is pressed within 20 seconds, the controller will
automatically exit parameters setup without saving the modified parameters
(under parameters setup status, system running in original parameters). Under
parameters setup status, SET key does not work.

Note:

1. During parameters setting condition, system runs under original parameters.
2. Under constant temperature control mode, the water temperature is controlled by
parameter F0;
3. Under intelligent control mode, the water temperature will be automatically

adjusted according to temperature changes. The temperature difference is
commanded by F1.
