Claim Text:
1. An adhesive dispensing system, comprising: a heater unit adapted to melt and heat an adhesive to an application temperature; a level sensor for detecting a level of adhesive remaining for melting and heating by said heater unit; a fill system operative to supply the adhesive to said heater unit; a controller configured to actuate said fill system to supply the adhesive when said level sensor detects that the level of adhesive is below a refill threshold, the controller also configured to operate said heater unit to maintain a unit set point temperature that is sufficient to melt and heat the adhesive to the application temperature; and a timer operatively coupled to said controller and configured to track an elapsed time since the most recent actuation of said fill system, such that said controller continues to operate said heater unit while reducing the temperature of said heater unit if the elapsed time tracked by said timer exceeds a first set threshold time.
