3.1.4 Controller Simmer Mode Adjustment
NOTE: The SMS III Controller simmer temperature is adjustable from 185ºF to 215ºF (85° to
102°C). There are two versions of this controller; one is adjusted by programming, the other is
manually adjusted.
To determine which version of the controller you have, turn the controller off by pressing the
ON/OFF switch. The display will go blank. Press the Simmer (right thermometer icon) switch. If
Code appears in the display, the simmer mode setpoint is changed via programming; if not, skip to
Manual Adjustment below.
1. Press 1, 6, 5, 0 to enter the programming mode. The currently programmed simmer setpoint will
be displayed. If the setpoint is not correct, enter the desired setpoint (for example, press 2, 0, 0
to program the simmer setpoint to 200º.
2. Press the Simmer switch again to lock in the setpoint, then press the ON/OFF switch to turn the
controller on and return to the normal operating mode.
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 5ºF (2°C) of the desired simmer temperature, nothing more needs to be
done. If it is not within 5ºF (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.
¼ turn will change the setpoint about 10ºF (5°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 5ºF (2°C) of desired temperature.
5. Replace the plug in the controller, close the control panel, and replace the screws removed in
Step 1.
3.1.5 Toggling Between Fahrenheit and Celsius Temperature Display
1. There are two versions of the SMS Controller: one that can be toggled between Fahrenheit and
Celsius temperature display and one that cannot. To determine which version you have, turn the
controller off by pressing the Power switch. The display will go blank. Press the Simmer
switch. If Code appears in this display, the temperature display can be changed. If not, the
display cannot be changed.
2. If Code appears in the display, press 1, 6, 5, 8. The display will toggle from Fahrenheit to
Celsius, or from Celsius to Fahrenheit.
