4. General settings adjustment
Press SET key to enter into the user-defined status. Meanwhile, PARAM SET is
on, indicates controller in parameters setting status.
Constant temperature mode displays setting water temperature value (Default
setting value is 25℃).
Press buttons can change setting value. Press confirm button
“RST” to save and exit after modified the values, then new values is working.
(Means F0 modified to new values, the chiller is running under new values).
If there is no more action within 20 seconds, it will automatically exit modifying
status without saving parameters.
