Thermostat Adjustment:
For equipment manufactured before April 2004
The brewer’s water tank temperature is factory set at 203
°F (slightly lower for high altitudes, to prevent boiling).
This setting will deliver water at 195
°F ± 5° to the coffee grounds.
Measure the temperature by holding a thermometer in the stream of water flowing out of the hot water faucet. The
temperature should be 195
°F ± 5°.
If an adjustment is necessary:
• Remove the upper cover of the unit.
• The thermostat is located in the upper section of the brewer. Locate the
• The thermostat is located in the upper section of the brewer. Locate the
adjustment stem, which may be taped to the thermostat.
• Insert the stem into the adjustment hole.
• Turn the adjustment stem slightly counterclockwise (as viewed from the stem
• Turn the adjustment stem slightly counterclockwise (as viewed from the stem
insertion point) to increase the temperature, and clockwise to decrease the

temperature.
• If you decreased the temperature setting, run 2 or 3 brew cycles to allow
enough cold water into the brewer to lower the tank temperature.
• Wait for the “ready” light to come on, and measure the temperature again.
• Repeat until the desired temperature is obtained.
• Replace the cover(s).
• Repeat until the desired temperature is obtained.
• Replace the cover(s).
Effective April 2004:
A new digital thermostat and temperature probe were introduced as a direct replacement for the old style
thermostat and probe.
During normal operation, the digital readout displays the last two digits of the actual water temperature. When the
adjustment knob is turned, the readout begins flashing to indicate the set point, not the actual temperature. After
the knob is released, the readout stops flashing and displays the actual temperature again.
A red LED lights when the power to the thermostat is on. A yellow LED lights when the thermostat is calling for
heat.
To adjust, turn the adjustment knob. The display will flash, indicating that the display is showing the set point, not
the actual temperature.
