Kind Code:

Abstract:
When a steam trap control unit detects a malfunction for the first time within a prescribed period (S12), a blockage-resolving operation , which is an operation for resolving a blockage phenomenon, is performed (S13). If the period up to the point in time at which a malfunction is detected again after the blockage-resolving operation is performed is equal to or less than a first threshold (S22, S23), a first malfunction prevention operation, which is the operation having a higher priority ranking from among a blockage reoccurrence prevention operation and an air binding prevention operation, is performed (S24). If the period up to the point in time at which a malfunction is detected for the third time after the blockage-resolving operation is performed is equal to or less than a second threshold (S32, S33), a second malfunction prevention operation, which is the operation from among the blockage reoccurrence prevention operation and the air binding prevention operation that was not selected as the first malfunction prevention operation, is performed (S34).
