The control device is provided with a digital clock (3) which is arranged in a housing (1) and has a display window (2), numbers (4) and lamps (5) for indicating the day of the week. Three memories are periodically interrogated by the clock (3). A first group of keys (14 to 22) opens the memories to display programs or for reprogramming, one half (14 to 17) for a weekday program and the other half (18 to 24) for a program for a non-working day. A second group of keys (23 to 28) arranged separately from the first group is assigned in each case a set value of the operating state, for example of a heating system. Programming is effected by simultaneously actuating in each case one key (14 to 21 or 22) of the first group and one key (23 to 26 or 27, 28) of the second group. By actuating only one of the keys (23 to 28) of just the second group of keys, it is possible to immediately call up the operating state corresponding to the key without changing the programming. The keys (14 to 22) and resetting keys (6 to 10) for the digital clock (3) can be covered by a flap (34). An interrogation key (32) serves to interrogate the instantaneous operating state. <IMAGE> |
