1. A controller to select and execute one of first air conditioning control and second air conditioning control, the controller comprising:
a connection interface unit to be connected to an air conditioner;
a communication interface unit to perform communication;
a display unit to display a display screen; and
processing circuitry to control the connection interface unit, the communication interface unit, and the display unit; wherein
in a case where the first air conditioning control is executed,
the connection interface unit is connected to the air conditioner,
the communication interface unit is connected to a first network,
the processing circuitry is configured to
cause the display unit to display a first display screen in accordance with first screen customizing information for generating the first display screen for controlling the air conditioner, and control the air conditioner by using the first display screen,
in response to the first screen customizing information being changed in order to change the first display screen, send first setting information from the communication interface unit to a server connected to the Internet via a first firewall connected to the first network, the first setting information indicating a changed part of the first screen customizing information,
transmit, to the server via the communication interface unit, a request for renewal information, and
in response to receipt, from the server via the communication interface unit, of renewal information indicating a changed part of screen customizing information for generating a remote display screen, change, by changing the first screen customizing information in accordance with the received renewal information, the first display screen so that the first display screen is to be identical to the remote display screen, the remote display screen being a display screen to be displayed in a remote controller not connected to the air conditioner; and
in a case where the second air conditioning control is executed,
the connection interface unit is not connected to the air conditioner,
the communication interface unit is connected to a second network,
the processing circuitry is configured to
cause the display unit to display a second display screen for controlling the air conditioner in accordance with second screen customizing information for generating the second display screen,
in response to the second screen customizing information being changed in order to change the second display screen, send second setting information indicating a changed part of the second screen customizing information from the communication interface unit to the server connected to the Internet via a second firewall connected to the second network,
transmit, to the server via the communication interface unit, a request for renewal information, and
in response to receipt, from the server via the communication interface unit, of renewal information indicating a changed part of screen customizing information for generating a local display screen, change, by changing the second screen customizing information in accordance with the received renewal information, the second display screen so that the second display screen is to be identical to the local display screen, the local display screen being a display screen to be displayed in a local controller directly connected to the air conditioner.
