A control system for a coffee brewer having a microprocessor in which the water heated in the heater tank must be a predetermined temperature before brewing. A double brewing cycle is prevented. Upon the system not being activated for a period of time, i.e., the water temperature is allowed to drop a greater magnitude for energy saving and component protection.

[ What is claimed is:] [1.] Apparatus for brewing a beverage and for keeping a brewed beverage warm, wherein a beverage is brewed by heating water and delivering heated water to a product to be brewed by passing hot water through said product to extract flavor therefrom, and dispensing a brewed product into a carafe;wherein said apparatus comprises a microprocessor, a water heater tank having a controllable heating element therein, delivery means operatively coupled to said water heater tank to initiate a brewing cycle and to deliver a predetermined volume of heated water which is heated at least to a first predetermined temperature below boiling to said product during each selected brewing cycle, temperature detection means for determining the temperature of said heated water at any time under the control of said microprocessor and for initiating a heating cycle for said heated water whenever its temperature drops below a second predetermined temperature which is lower than said first predetermined temperature, and actuator means to preclude delivery of said heated water to said product when the temperature thereof is below said predetermined temperature, said apparatus further comprising:a primary warmer plate, and at least one secondary warmer plate;respective switch means to turn on each warmer plate and to turn off each warmer plate;countdown timer means associated with each warmer plate to count down at least a first selected time period for each respective warmer plate, each time a respective warmer plate is turned on;reset means for turning on a respective secondary warmer plate and for initiating a new timed countdown period for each secondary warmer plate each time a fresh brewed beverage carafe is placed thereon;reset means for initiating a new first selected timed countdown period for said primary warmer plate, and for turning on said primary warmer plate, each time delivery of said predetermined volume of heated water to said product has started after a new brewing cycle is initiated; andturn-off means for turning off all of said warmer plates when said first selected timed countdown period for said primary warmer plate is concluded, and for initiating a cool down period for said apparatus.
