Abstract
Official abstract text for this publication.
A first reset switch is attached to a combustion controlling device. A second reset switch is installed at a remote place distant from the combustion controlling device. A first reset input from the first reset switch is received without any restriction to release the lockout. A reset input from the second reset switch is received with any restriction to release the lockout. Specifically, when the lockout releases are performed for a predetermined number of times or more upon receiving the reset input before a predetermined time elapses after the lockout has been released upon receiving the initial reset input, the release of the lockout upon receiving the reset input is prohibited until the predetermined time elapses.
First claim
Opening claim text (preview).
What is claimed is: 1 . A combustion controlling device for controlling the operation of a combustion device, comprising: a lockout portion that detects an abnormality of the combustion device to put the combustion controlling device into a lockout state; a first reset switch that is attached to the combustion controlling device; a second reset switch that is provided at a remote place distant from the combustion controlling device; a first lockout releasing portion that receives a first reset input indicative of an operation restart of the combustion device from the first reset switch without any restriction to release the lockout state of the combustion controlling device; and a second lockout releasing portion that receives a second reset input indicative of the operation restart of the combustion device from the second reset switch with any restriction to release the lockout state of the combustion controlling device, wherein when the second lockout releasing portion releases the lockout state of the combustion controlling device upon receiving the second reset input by a predetermined number of times or more before a predetermined time elapses after the second lockout releasing portion receives an initial second reset input and releases the lockout state of the combustion controlling device, the second lockout releasing portion prohibits the release of the lockout state of the combustion controlling device upon receiving the second reset input until the predetermined time elapses. 2 . The combustion controlling device according to claim 1 , further comprising an informing portion which informs that the release of the lockout state by the second reset switch cannot be performed while the release of the lockout state of the combustion controlling device upon receiving the second reset input is prohibited.
