Why is the water not cooling?Updated 2 months ago

If your chiller isn’t cooling the water as expected, and the temperature seems off despite proper circulation, the issue might be related to the chiller's settings. 

Here’s a step-by-step guide to troubleshoot and resolve the problem:

1. Ensure Proper Operation: Confirm that the chiller is turned on and the water is circulating correctly. If you don't have water flow then first read this article: Why is my water not circulating/pumping?

2. Give it a Chance!

Oftentimes the chiller will cool the water, you just need to give it enough time to do so.  The chiller is designed to run 24/7 and keep the water cool indefinitely - but in some cases can take as long as 13 hours (depending on environmental conditions) to bring the water down to ideal temperature.  Make sure water is circulating and that you hear the fans/compressor kick on and leave the chiller for a full 24 hours to make sure there is truly a problem.

3. Verify and Adjust the F1 Setting:

• Press and hold the SET button for 3-5 seconds until "F1" appears on the display.
• Press the SET button again (do not hold it down).
• A number will appear; ensure this number is set to 3 (Fahrenheit). If not, adjust it accordingly.
• Press the RST button once to save the setting.

The F1 setting determines when the chiller restarts after reaching the desired temperature. For example, if you set the temperature to 40°F and F1 to 3°F, the chiller will cool the water to 40°F and restart when the temperature rises to 43°F (40+3°F). If the F1 setting is incorrectly set to a higher value, such as 30°F, the chiller will only restart after the temperature rises by 30°F above the set point.

4. Adjust the F2 Setting (if needed):

• Press and hold the SET button for 3-5 seconds until "F1" appears on the display.

• Click the arrow UP button once, you will now see F2 on the display

• Click the SET button again (do not hold it down this time)

• A number should appear, this number should always be set at 0 (Fahrenheit) if it isn't already.

• The F2 setting should always be set to 0°F to ensure proper operation unless our team tells you to change it.
