Brewer system with brew status indicator and method
First Claim
1. In a brewing system having a brewer with a brew cycle start switch to start a brew cycle and a brew cycle status light associated with the start switch, the improvement being a brew cycle status light controller, comprising:
- means for causing the light to operate in a first mode of operation if the brew cycle start switch has not been activated to start a brew cycle;
means for causing the brew cycle status light to operate in a second mode different from said first mode in response to actuation of the brew cycle start switch before the brewing system is ready and enabled to properly perform a brew cycle; and
means for causing the brew cycle status light to operate in a third mode different from both said first and second modes during performance of a brew cycle;
said causing means including a microprocessor controller and a controller interface circuit for interfacing at least one sensor of the sensing means with the microprocessor controller for conveying information to the microprocessor controller indicative of whether the brewer is ready to properly perform a brew cycle, said controller responding to the actuation of the start switch to control the modes of operation in accordance with ready indicative information being provided by the at least one sensor; and
in whichthe brewing system includes another brewer with another start switch and another brew cycle status light and the controller is responsive to one of the one and the other brewers performing a brew cycle to cause the brew cycle status switch of the other one of the brewers to enter into the second mode in response to actuation of the start switch of the one and the other brewers.

Abstract
A twin brewer system (30) with a pair of brewers (30A, 30B) each with a controller (158) for controlling the application of electrical power to a hot water heater, disables the application of electrical power to the heater (154) of one brewer (30A, 30B) in response to actuation of a start brew switch of the one brewer (30A, 30B) while electrical power is being applied to the heater (154) of the other brewer (30A, 30B). The controllers also respond to a hot water quantity sensor (164, 168) and a responsive delay circuit for disabling dispensing of hot water in response to actuation of the brew start switch (50) until a sufficient quantity of hot water is in a hot water dispenser tank (152) needed for the brew cycle. Indication lamps indicate when the brew cycle is being delayed and when brewing is not being performed. Actuation of a single emergency stop switch (138) stops hot water dispensing of both brewers (30A, 30B).

2. In a brewing system having a brewer with a brew cycle start switch to start a brew cycle and a brew cycle status light associated with the start switch, the improvement being a brew cycle status light controller, comprising:
- means for causing the light to operate in a first mode of operation if the brew cycle start switch has not been activated to start a brew cycle;
means for sensing when the brewing system is ready and enabled to properly perform a brew cycle;
means responsive to the sensing means for automatically causing the brew cycle status light to operate in a second mode different from said first mode in response to actuation of the brew cycle start switch before the brewing system is ready and enabled to properly perform a brew cycle;
means for causing the brew cycle status light to operate in a third mode different from both said first and second modes during performance of the brew cycle; and
means to disable the performance of a brew cycle in response to actuation of the start switch when the brew cycle status light is in the second mode.
- means for causing the light to operate in a first mode of operation if the brew cycle start switch has not been activated to start a brew cycle;

6. In a brewing system having a brewer with a brew cycle start switch to start a brew cycle and a brew cycle status light associated with the start switch, a method of controlling the brew cycle status light controller, comprising the steps of:
-
operating the light in a first mode of operation if the brew cycle start switch has not been activated to start a brew cycle; operating the brew cycle status light in a second mode different from said first mode in response to actuation of the brew cycle start switch before the brewing system is ready and enabled to properly perform a brew cycle; operating the brew cycle status light in a third mode different from both said first and second modes during performance of a brew cycle; and
in whichthe controller keeps the brew cycle status light in the second mode until the sensor indicates that the brewer is ready to properly perform a brew cycle and then switches the brew cycle status light to the third mode and simultaneously initiates a brew cycle.
