Step 8: The display should now read “New Dilute Flow” along with the correct ow rate

of the bypass in ounces per minute. After about 5 seconds, the display will return to the

“Calibrate Flow?” screen.

Master Tank Temp

The Master tank temperature is the maximum temperature for the tank. The Set Recipe Temps allows the operator to

set temperature for all recipes and will override the Master temp.

Explanation:

Setting recipe temps will override the Master Temp. The tank will hold at the lowest temperature between the three

selected recipes stored in the brew buttons. For instance, let’s say Brew A’s recipe temperature is set at 205°, Brew

B’s recipe temperature is set at 205°, and Brew C’s recipe temperature is set at 200°. The tank will hold at 200°. If

Brew A or Brew B is pressed, the tank will heat to the 205° temperature. The brew button must be pressed again in

order for a brew to start. After the completion of that brew, the tank will return to the 200° holding temperature. It may

take awhile for the tank to return to the lower temperature.

Calibrating the Temperature Sensing Probe (Thermistor)

NOTE: Variables such as tank set temperature could show different numbers than the example shown here. Tank

must be at it’s ready temp before calibrating.

1. Remove silicon vent tting from tank lid.

2. Insert a digital temp probe through the exposed vent hole in tank lid to the same depth as the factory temp probe.

3. Press and hold the “Hidden” button until display reads “CAL TEMPERATURE SENSOR?” “NO/YES”

4. Select “YES”. The display should show something similar to the screen below.

5. Press the + (Control) button to increase or - (Digital) button to decrease temperature reading until

it matches the reading on the thermometer.

6. Exit program mode, remove thermometer, and install vent tting. Calibration is complete.
