CHAPTER 1: Overview/Component Replacement
1-4
• Remove the product and press the timer key to halt the alarm.
• Press Boil key a second time to return to simmer mode.
1.3 Programming
• Remove the bezel (see annotated photo on page 3-1) Lift up and then rotate out at the
bottom, which exposes a keypad beside each timer button.
• Temperature change: Press the temperature key until the current temperature is displayed.
Enter the desired temperature with the key pad.
• An illuminated dot between the last digit and the F indicates the change was accepted.
Temperatures below 155°F and above 210°F can’t be entered. The computer will default to
its lowest setting, 155°F, upon low-temperature entry and to its highest setting, 210°F, upon
high-temperature entry.
• Time change: Press the temperature key until the display alternates between S inn and a
dashed line. Enter the desired time, in minutes and seconds, on the key pad. Press the timer
key to ensure the desired time is in place. Press the timer key a second time to stop the timer.
• Turn the controller OFF. Replace the bezel. Ensure it doesn’t press against the key pads.
1.4 Functional Description
With the main power-switch on, 24-volts is supplied to a relay, which controls the water solenoid. If
the upper float switch is closed (low-water position), the relay is closed and the solenoid opens. It is
not necessary for the controller to be on for the pot to fill.
Twelve volts is also supplied to the controller. The low-level float switch must close to allow signals
from the controller to reach a relay, which, when closed, sends 24 volts through the high limit to the
contactor. The unit won’t heat with the float switch open.
With the controller on, the temp probe monitors the water temperature. The controller calls for heat,
when necessary, by closing the 24-volt relay, which closes the contactor and energizes the elements.
