Explaining F1 and F2 SettingsUpdated 2 years ago
To adjust the F1 and F2 settings on your Deep Dive Wellness chiller, follow these steps:
F1 Setting: Cooling Cycle Frequency
F1 Setting Adjustment:
Press and hold the SET button for 3–5 seconds until "F1" appears on the display.
Press the SET button again (briefly, don't hold it down).
You'll see a number. If it's not already set to 2°F (Fahrenheit), we recommend setting it to that.
Finally, press the RST button once to save the setting.
For example, if you set the desired temperature to 40°F and the F1 setting to 2°F, your chiller will cool the water to 40°F and then stop. It will restart cooling when the water temperature rises to 42°F (40°F + 2°F). If you set the F1 setting to 4°F, the chiller will start cooling at 44°F (40°F + 4°F).
F2 Setting: Temperature Correction
Thermostat Calibration:
Regarding the F2 setting, which is mainly for repair and usually doesn't need adjustment under normal circumstances:
Press and hold the SET button for 3–5 seconds until "F1" is displayed.
Press the UP "▲" button once to display "F2" on the screen.
Press the SET button again (without holding it down).
You should see a number, which should always be set to 0 (Fahrenheit).
If the chiller's thermostat displays a temperature different from the actual water temperature and requires adjustment:
Suppose the actual water temperature in the tub is 60°F (16°C), but the LCD displays 55°F (13°C). The difference is 60°F - 55°F = 5°F / 16°C - 13°C = 3°C. Follow these steps:
Long-press the "SET" key for 4–6 seconds. After "F1" appears, use the "▲" + button or "▼" – button to choose "F2" and then press the "SET" key.
Press the "▲" + button to adjust to 5°F (3°C).
Press the "RST" key to save.
For instance, to correct the thermostat reading of 117°F when the actual water temperature is 39°F, adjust F2 to 39 - 117 = "-78".
By following these steps, you can effectively adjust the F1 and F2 settings as well as calibrate your chiller's thermostat for accurate temperature readings.
