Abstract
Abstract A programmable control apparatus for a heating installation of the type that comprises a clock (8) and a processing unit (2) is provided to control one or more heating appliances of the installation according to programming data. The programming data are either programming data stored in the memory of a card (11), of the type that is known as "smart cards." This data is read out when such a card (11) is introduced into a reader (10) of the apparatus. The programming data resident in the processing unit (2) operates the heating system when no card is introduced into the reader (10). The stored programming data can be manually modified only if a card (11), known as a "key card", is introduced into the reader (10).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
240 words
An apparatus for controlling a heating system in any of a plurality of different modes selected in response to a use of a plurality of different types of cards, said apparatus comprising: data processing means coupled to control said heating system, keyboard means coupled to said data processing means for storing a resident program in said data processor for controlling said heating system in a predetermined manner, card reading means coupled to said data processor, a plurality of different types of cards, means responsive to said card reading means in an absence of a card for establishing a first mode of operation deactivating said keyboard and operating said system in response to sensors, means responsive to a first type of card for causing said card reading means to activate said keyboard means in order to enable a modification of the resident program, means responsive to a second type of card having thereon a memory containing specific data for deactivating said resident program and operating said heating system according to a program stored in said memory on said second type of card, means responsive to a third type of card having thereon a memory containing a user identification number and a stored program for modifying said resident program responsive an entry of said user identification number, and means responsive to a fourth type of card for enabling a user to control said system in response to keying in an identification number.
