Patent ID: 8123095

Claim:
A method of controlling combustion-operated setting tool having a ventilator ( 16 ) for a combustion drive and a control unit ( 30 ) for controlling the ventilator, comprising the steps of: triggering a setting process ( 44 ) after a trigger switch signal has been detected ( 43 ); reading out ( 45 a ) from the data storage ( 31 ) the modeled thermal control parameter of a preceding setting process (T-old), the timestamp (t_old), and the ventilator operating data; modeling ( 46 ) a new thermal control parameter (T_new) ( 46 ) based at least on the thermal control parameter of the preceding setting process (T_old), the timestamp (t_old), a current time (t_new), the ventilator operating data, and based on heat supply constant (K 2 ) and heat discharge constant (K 1 ); and storing ( 52 ) the new modeled thermal control parameter (T_new) of the combustion drive in the data storage ( 31 ) as a modeled thermal control parameter (T_new) of a preceding setting process (T_old), storing the current time (t_new) in the data storage ( 31 ) as a timestamp (t_old), and storing the ventilator operating data in the data storage ( 31 ).
