1. A temperature control device in combination with a fill water displacement beverage brewing apparatus, said brewing apparatus having a brew cycle during which a selected volume of heated water is dispensed from the beverage brewing apparatus to infuse a beverage brewing substance from which a beverage is brewed;

  • said beverage brewing apparatus including a heated water reservoir for retaining a predetermined volume of water in a heated state, a controllable water heater operatively associated with said heated water reservoir for heating the water in the reservoir over a heating cycle of predetermined duration and maintaining the water in the reservoir within a predetermined temperature range, a temperature control device comprising sensor coupled with said controllable water heater for sensing the temperature of water retained in said reservoir and selectively energizing and deenergizing said controllable water heater when the water temperature is respectively below or above a predetermined maximum temperature, a basin communicating with said reservoir for retaining a measured volume of water prior to being dispensed into said reservoir;

    said temperature control device further comprising control means operative substantially at the beginning of the dispensing of water from the basin to the reservoir, for activating said controllable water heater and momentarily overriding said sensor regardless of the temperature of the water in the heated reservoir, said controllable water heater being activated by said control means independent of said sensor for a time period predetermined by a timing mechanism operatively associated with said control means such that during the overriding of the sensor the activation of the water heater is independent of the temperature of the water retained in the reservoir.
