KST – KROMSCHRÖDER SYSTEM TECHNOLOGY
The function block (210) monitors and controls the combustion air supply. The air may be supplied by a fan or a compressed air supply, for example. The control system may differ from the specified example depending on the supply medium.
Whether the combustion air supply is started direct or using a star-delta system depends on the rating of the motor or the rating up to which the customer’s energy supplier permits direct starting.
