Description

  The present invention relates to an air conditioning system controller having a plurality of air conditioning groups.

  For example, an air conditioning system having a plurality of air conditioning groups divided for each area to be air-conditioned is known, as in the method described in Patent Document 1 (Japanese Patent Laid-Open No. 2008-196777).

  The controller of such an air conditioning system is provided with a liquid crystal display, a cross key, a determination button, and the like. When trying to operate a certain air conditioning group, the cross key is pressed several times to select the air conditioning group. The determination button is pressed while the cursor is positioned on the air conditioning group from among the plurality of air conditioning groups displayed on the liquid crystal display unit. As a result, a screen on which the setting operation can be performed for the air conditioning group is displayed on the liquid crystal display unit.

  However, in the controller of the air conditioning system described in the above-mentioned Patent Document 1 (Japanese Patent Laid-Open No. 2008-196777), it is necessary to repeatedly press the cross key repeatedly to position the cursor on a specific air conditioning group. The more air conditioning groups that are managed, the more complicated processing is required to select an air conditioning group.

  On the other hand, in order to change the screen displayed on the liquid crystal display unit directly to the setting screen for performing a setting operation for a specific group, individual direct keys are provided on the remote control for each air conditioning group. It is possible. Thereby, the setting screen for the specific air conditioning group to be operated can be displayed with a simple operation.

  However, in an air conditioning system having a plurality of air conditioning groups to be managed as described above, when the setting screen for each air conditioning group is to be displayed directly, the configuration of the direct key described above is also used in the conventional cross key configuration. Similarly in the configuration, from the time when the input operation by the user is performed, until the setting screen of the specific air conditioning group is read from the plurality of air conditioning groups and is displayed and output on the liquid crystal display unit, The problem that some time lag occurs cannot be solved.

  For this reason, the user who performed input operation will be in the situation which cannot be sure whether the input operation which he performed is recognized by the controller, and may feel discomfort. Such a time lag tends to become longer as the microcomputer incorporated in the controller is made cheaper.

  The present invention has been made in view of the above points, and an object of the present invention is used in an air conditioning system having a plurality of air conditioning groups, and can reduce a sense of incongruity that occurs when a specific air conditioning group is set.
