A controller and regulator (4), which can be fitted to a heating boiler and has a time switch for a heating program is additionally influenced by a room apparatus (1) which is arranged in the living room and is connected via only two leads (2, 3) which can be interchanged. A room-temperature sensor (11) can have fixed resistors connected to it in series, which fixed resistors differ depending on the position of a switch (15). An analog/digital converter (10) and a computer (R) of the electronic regulator (5) which is contained in the regulator (4) detect both the position of the switch (15) and the room temperature ( theta R) on the basis of the resistance value between the two leads (2, 3). The following variables are transmitted: actual room temperature value and desired room temperature correction, as well as three positions of the switch (15) for influencing the time heating program. <IMAGE> |
