F1 & F2 settings explained (temperature sensor control)Updated 17 days ago

If you ever want to adjust how quickly the Chiller turns back on or you’re noticing a larger temperature swing than expected you can check the F1, F2 and F3 settings on the digital controller.

F1 setting:
This controls how much the water is allowed to warm up before the compressor starts cooling again. It’s preset to 3°F, meaning if your target is 43°F, the Chiller will begin cooling again once the water reaches 46°F. This setting helps balance energy use and cooling consistency

To set this setting follow the instructions below:

1. Press and hold the SET button for 3-5 seconds until the chiller shows the "F1" text on the display

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

3. A number should appear, we recommend setting this number to 3°F if it isn't already.

4. lastly, click the RST button once to save the setting.

F2 setting:
This is a sensor calibration setting and should always be preset to 0°F. But if the display temperature doesn’t match the actual water temperature in your tub, check that this setting is still at 0°F. If it is and you’re still seeing a discrepancy, reach out to our Chiller Support Team and they’ll be happy to help.

To set this setting follow the instructions below

1. Press and hold the SET button for 3-5 seconds until the chiller shows the "F1" text on the display

2. Click the arrow UP button once, you will now see F2 on the display
3. Click the SET button again (do not hold it down this time)
4. A number should appear, this number should be pre set at 0°F.

F3 setting (Only standard chiller):
The F3 setting is preset at the factory and should only be adjusted if instructed by our team. This setting determines how many minutes the compressor waits before it turns on.

To set this setting follow the instructions below:

1. Press and hold the SET button for 3-5 seconds until the chiller shows the "F1" text on the display

2. Click the arrow UP button two times and you will now see F3 on the display
3. Click the SET button again (do not hold it down this time)
4. A number should appear, this number should always be set at 3min.
