In recent years, a control system is constructed in each individual space so that the air-conditioning supply pipe is opened and closed by the operation of the control system, so that the supply of air-conditioning is blocked even when a person is absent.

However, such a control system is often not practical operation because the operator or worker must go to the location to operate directly.

In other words, if a worker or worker leaves the office, continuous supply of cooling and heating is provided unless the control system is operated. Therefore, the building manager in charge of the guard visits each individual space and manually controls the control system to block the supply of heating and cooling. It was necessary to do this, which caused cumbersome problems of the work.
