Selecting Intelligent or Constant Mode on CW-5000 Series Chillers

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 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.

Here is how to change to constant temp mode from intelligent mode:

1. Press and hold “▲” button and “SET” button for 5 seconds

2. Until “00” is displayed

3. Press “▲” button to select the password “08”. (Default setting is 08)

4. Press “SET” button to enter menu setting

5. Press “▲”button until F3 is displayed (F3 stands for way of control)

6. Press “▼” button to change the data from 1 to 0. (1 means intelligent temperature control mode while 0 means constant temperature mode)

7. Press “RST” button to save the modification and exit setting
