Our chillers come programmed to intelligent mode for the T-503 temp controller (CW-5000 series) and constant mode for t-504 (CW-6000 series) controllers.
Intelligent mode means the water temperature will be maintained within a few degrees of the ambient air temperature as defined in the chiller controller settings.
Constant mode means the temp will be maintained within a few degrees of the set point (usually 20c).
Intelligent mode is fine in most cases, especially if the chiller is in a conditioned space.
Constant mode may be warranted if the chiller is in a non-conditioned environment.
How to Change to Constant Temp Mode from Intelligent Mode
- Press and hold "▲" button and "SET" button for 5 seconds
- Until "00" is displayed
- Press "▲" button to select the password "08". (Default setting is 08)
- Press "SET" button to enter menu setting
- Press "▲" button until F3 is displayed (F3 stands for way of control)
- Press "▼" button to change the data from 1 to 0. (1 means intelligent temperature control mode while 0 means constant temperature mode)
- Press "RST" button to save the modification and exit setting
