Enter Parameter Mode
- Press and hold SET + ▲ for a few seconds until PA5 appears.
- Set PA5 = 8 (default password) and press SET to confirm.
Enable Constant Temperature Control
- Navigate to F3 and set it to 1 (Enables manual control instead of automatic adjustment).
Set Minimum Allowable Temperature
- Navigate to F9 and lower it using the arrow keys (Defines the lowest possible cooling temperature).
Set Maximum Allowable Temperature
- Navigate to F8 and lower it to the desired max temperature (Prevents the chiller from exceeding this value).
Save & Exit
- Press RST to save changes and return to normal operation.
The chiller operates between F9 (minimum temperature) and F8 (maximum temperature). The system will cool until it reaches F9, then stop until the temperature rises back toward F8. Adjusting these values narrows or expands the cooling range, controlling how aggressively the chiller maintains the desired temperature.
