Abstract: A flexible, linked system which can be implemented at low cost for remotely communicating with domestic appliances with their large number of appliance-specific interfaces is afforded if the domestic appliances are connected to a house central station which is equipped with basic software for interrogating the identification of the domestic appliances. By way of the ascertained identification, the house central station obtains from a database the bus access software required for access to the appliance-specific interface and stores it and thus permits communication by way of the appliance-specific interface of the respective appliance.

Abstract: A device for displaying and operating a remotely adjustable room regulator has a space-saving display panel fitted with LEDs and an operating panel equipped with pushbuttons. To reduce the power consumption and thus to increase the service life of a battery for supplying voltage to the display panel, the operating mode display is effected only for a predetermined period of time from manually or program-controlled switching over into the current operating mode. Thereafter the display panel remains deactivated.
