Control device for at least one heating, air-conditioning, ventilation or refrigeration system

摘要

The invention concerns a control device for at least one heating, air-conditioning, ventilation or refrigeration system with a memory for a temperature control program and a signal outlet. It is endeavoured to simplify the programming. For this purpose, the memory is arranged in an element (5), which comprises a communication interface (6) and which can be dismounted from the control device, the communication interface (6) being connectable to an external input device and the control device (1) comprising an electrical supply device (3) which can transmit electrical energy to the element (5).
