Anschluß von Sensoren an einen ReglerConnecting sensors to a controller

Bei einigen Raumtemperaturreglern gibt es einen separaten Anschluß zur Absenkung der Heiztemperatur. Hier kann ein Fensterkontakt angeschlossen werden, der verhindert, daß Räume bei geöffnetem Fenster übermäßig beheizt werden. Wird eine zweite Möglichkeit zur Temperaturabsenkung gewünscht, beispielsweise durch eine Schaltuhr zur Nacht oder während der Ferien, so muß ein zusätzlicher Anschluß vorgesehen werden.Some room temperature controllers have a separate connection for lowering the heating temperature. A window contact can be connected here, which prevents rooms from being heated excessively when the window is open. If a second option for lowering the temperature is required, for example using a timer at night or during the holidays, an additional connection must be provided.

Dieser Anschluß verursacht erheblichen Mehraufwand. Mit der in Fig.l angegebenen Schaltung entfällt die Notwendigkeit eines zusätzlichen Anschlusses. Mit der Schaltuhr oder einem anderen zentralen Geber 2 wird im Normalbetrieb eine positive Spannung abgegeben. Diese wird über Diode 4 und den Fensterkontakt 3 an den Regler 1 angelegt. Nur bei geöffnetem Fenster erhält der Regler ein Signal zum Absenken. Wird Absenkung von dem zentralen Geber 2 gewünscht, legt dieser eine negative Spannung an. Die Diode 4 sperrt, Diode 5 wird leitend, und der Regler fährt unabhängig vom Fensterkontakt Absenkung.This connection causes considerable additional work. The circuit shown in Fig. 1 eliminates the need for an additional connection. A positive voltage is output in normal operation using the timer or another central sensor 2. This is applied to the controller 1 via diode 4 and the window contact 3. The controller only receives a signal to lower the temperature when the window is open. If a reduction is required from the central sensor 2, it applies a negative voltage. Diode 4 blocks, diode 5 becomes conductive, and the controller lowers the temperature independently of the window contact.

Auf diese Weise reicht ein Klemmenpaar aus, um zwei Geber an einen Regler anzuschließen.In this way, one pair of terminals is sufficient to connect two sensors to one controller.
