Manual Adjustment
1. With the unit in the simmer mode, place the tip of a good grade thermometer near the temperature
probe and determine the actual water temperature in degrees Fahrenheit. If the temperature is within
±5
° F (2 ° C) of the desired simmer temperature, nothing more needs to be done. If it is not within ±5 ° F
(2
°
C) of the desired temperature, perform Steps 2 through 5.
2. With the unit in the Simmer Mode, open the control panel by removing the screws in the upper corners
and tilting the panel out.
3. Remove the black rubber plug from the top of the controller housing.
4. Using a small, flat-tipped screwdriver, turn the adjusting screw to change the simmer setpoint. A ¼
turn will change the setpoint about 10
°
F (4
°
C). (You will have to experiment with the direction of
rotation to determine which way to turn to raise or lower the temperature). Wait at least 5 minutes, then
recheck actual water temperature. Repeat this step until the water temperature is within ±5
° F (2 ° C) of
desired temperature.
5. Replace the plug in the controller, close the control panel, and replace the screws removed in Step 2.
