Description
tontreiberstufen 13 und Strombegrenzungswiderstände 14 auf Katodenanschlüsse 15 bis 21 von zwei Mehrsegmentanzeigeelementen 22 und 23 geschaltet ist Einander entsprechende Segmente der Anzeigeelemente 22, 23 sind dabei parallelgeschaltet. Die Anoden jedes An-Zeigeelementes 22 bzw. 23 sind für sich zusammengeschaltet und an je einem Kollektoranschluß von als Sdnlter betriebenen Transistoren 24 bzw. 25 angeschlossen. Di> Emitteranschlüsse der Transistoren 24,25 sind gemeinsam mit einem Kontakt eines Tastschalters 26 verbunden, der an eine über einen Transformator 27 gespeiste Gleichstromversorgung 28 angeschlossen ist Von der Basis des Transistors 24 führt ein Widerstand 29 zum Kollektoranschhiß des Transistors 25, dessen Basis über einen Widerstand 30 mit seinem Emitter ver- is bunden ist. Von der Basis des Transistors 25 führt eine Leitung über einen Widerstand 21 und eine der Spannungsreduzierung dienende Zenerdiode 32 an eine Klemme 33 des Schaltungselementes 1, an der eine Rechteckspannung entsteht Durch diese Rechteckspannung mit einer Taktfrequenz von ca. 50 Hertz werden die Transistoren 24,25 wechselweise d?:rchgeschaltet und legen dadurch abwechselnd die Anzeigeelemente 22 bzw. 23 an Spannung, wenn der Tastschalter 26 bei Bedarf geschlossen ist Die Rechteckspannung läuft dabei synchron mit dem Takt des Multiplexsignals an den Katoden 15 bis 21 und wechsel so schnell, daß für das Auge beide Anzeigeelemente 22 und 23 gleichzeitig leuchten, sofern zweistellige Anzeigen anstehen.Sound driver stages 13 and current limiting resistors 14 on cathode connections 15 to 21 of two multi-segment display elements 22 and 23 are connected to each other corresponding segments of the display elements 22, 23 are connected in parallel. The anodes of each indicator element 22 and 23 are interconnected for themselves and each have a collector connection of as Sdnlter operated transistors 24 and 25 are connected. Di> emitter connections of the transistors 24,25 are jointly connected to a contact of a pushbutton switch 26, which is connected to a contact via a transformer 27 fed DC power supply 28 is connected from the base of the transistor 24 is a resistor 29 to the collector connection of the transistor 25, whose Base is connected to its emitter via a resistor 30. From the base of transistor 25 one leads Line via a resistor 21 and a Zener diode 32 serving for voltage reduction to a Terminal 33 of the circuit element 1, at which a square-wave voltage is generated by this square-wave voltage With a clock frequency of approx. 50 Hertz, the transistors 24, 25 are switched on alternately and thereby alternately energize the display elements 22 and 23 when the pushbutton switch 26 is attached Demand is closed The square wave voltage runs synchronously with the clock of the multiplex signal to the Cathodes 15 to 21 and change so quickly that both display elements 22 and 23 are visible to the eye at the same time light up if there are two-digit displays.
Die Schaltungsanordnung ist so getroffen, daß bei gedrückter Taste 26 die momentane Zeitgeberlaufzeit ab Niedertarif-Freigabe anzeigt wird. Um hierbei auch die vom Temperaturfühler ermittelte Außentemperatur anzeigen zu können, ist an eine Klemme 35 des Schaltungselementes 1 ein Temperaturtastschalter 36 angeschlossen, der einen dem Kodierer vorgeschalteten elektronischen integrierten Umschalter so steuert, daß dann das vom Temperaturfühler 4 abgeleitete digitale Signal dem Kodierer zufließt. Bei gedrückten Tasten 26 und 36 w^d daher die Außentemperatur angezeigt. Über einen dem Umschalter zusätzlich zugeordneten, an eine Klemme 37 angeschlossenen Laufa*.itschalter38 kann darüber hinaus ein Signal für die bereits innerhalb der möglichen Aufladedauer abgelaufene Zeit eingeschaltet und über den Kodierer an die Anzeigeelemente 22, 23 geführt werden. Im übrigen werden die aus der Zeil -jnd der Außentemperatur sich ergebenden Signale in dem Schaltungselement 1 entsprechend dem herrschenden Wärmebedarf gesteuert und über einen Impulsformerelement 39 a A die Steuerelektrode eines Triac 40 geleitet, an den Steuerwiderstände 41 in den einzelnen Wärmespeicheröfen parallel angeschaltet sind.The circuit arrangement is such that when button 26 is pressed, the current timer running time from the low tariff release is displayed. In order to be able to display the outside temperature determined by the temperature sensor, a temperature pushbutton switch 36 is connected to a terminal 35 of the circuit element 1, which controls an electronic integrated switch connected upstream of the encoder so that the digital signal derived from the temperature sensor 4 then flows to the encoder. When buttons 26 and 36 are pressed, the outside temperature is displayed. A signal for the time that has already elapsed within the possible charging time can also be switched on via a run switch 38 connected to a terminal 37, which is additionally assigned to the changeover switch, and can be sent to the display elements 22, 23 via the encoder. In addition, the signals resulting from the line -jnd the outside temperature are controlled in the circuit element 1 according to the prevailing heat demand and the control electrode of a triac 40 is passed via a pulse shaper element 39a A , to which control resistors 41 in the individual heat storage ovens are connected in parallel.
