Die vorliegende Erfindung bezieht sich auf eine elektrische Steuerung der Brennstoffzufuhr zum Brenner eines Heizkessels einer Warmwasserheizungsanlage mit einem die Brennstoffzufuhr zu diesem Brenner steuernden Magnetventil, wobei in der die Spule dieses Magnetventils mit Strom versorgenden Versorgungsleitung zumindest ein von einem im Vorlauf des Heizkessels angeordneten Heizkesselthermostaten betätigbarer bei Unterschreitung S einer Soll-Temperatur geschlossener Schaltkontakt und gegebenenfalls zusätzlich zumindest ein von einem Raumthermostaten oder einer witterungsgeführten Regelung betätigbarer Schaltkontakt in Reihe angeordnet sind und eine Umlaufpumpe mit ein« Stromversorgung vorgesehen sind.The present invention relates to an electrical control of the fuel supply to the burner of a boiler of a hot water heating system with a solenoid valve controlling the fuel supply to this burner, wherein in the coil of this solenoid valve supplying power supply line at least one of the boiler thermostats arranged in the flow of the boiler can be actuated If the switch contact falls below a set temperature and, if appropriate, at least one switch contact that can be actuated by a room thermostat or a weather-compensated control system is arranged in series and a circulation pump with a power supply is provided.
Aufgabeder Erfindung ist es, die Temperatur des Heizkesselwassers unabhängig von Schaltvorgängen, die durch diese genannten Thermostaten veranlaßt werden, oberhalb eines Mindestwertes zu halten, unterhalb dessen eine 10 Kondensatbildung im Wärmetauscher des Kessels zu befürchten istThe object of the invention is to keep the temperature of the boiler water above a minimum value, irrespective of switching operations caused by these thermostats, below which condensate formation in the boiler heat exchanger is to be feared
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß eine diesen Schaltkontakt umgehende Umgehungsleitung vorgesehen ist in der ein von einem weiteren Kesselwasserthermostaten betätigbarer bei Unterschreiten einer Soll-Temperatur geschlossener Schaltkontakt in Reihe mitder Spule eines Relais angeordnet ist das einen Arbeitskontakt und einen Ruhekontakt aufweist wobei letzterer in der Versorgungsleitung der Umlaufpumpe und ersteier in der den 15 Schaltkontakt des Kesselthermostaten überbrückenden Leitung angeordnet sind.According to the invention the object is achieved in that a bypass line which bypasses this switch contact is provided, in which a switch contact which can be actuated by a further boiler water thermostat and is below a set temperature is arranged in series with the coil of a relay which has a normally open contact and a normally closed contact, the latter in the Supply line of the circulation pump and first in the line bridging the 15 switching contact of the boiler thermostat are arranged.
Dieser zusätzliche Kesselthermostat vermag demnach in einer solchen Steuerung zuverlässig zu gewährleisten, daß die Temperatur - ungeachtet der Tätigkeit der übrigen Thermostaten - nicht unter eine Mindesthöhe absinkt, unterhalb deren mit einer Kondensatbildung und dementsprechend mit einer korrosiven Schädigung des Wärmetauschers gerechnet werden müßte. 20 Zu diesem Zweck ist der zusätzliche Kesselwasserthermostat auf eine die eine Kondensatbildung im Wärme tauscher vermeidende Soll-Mindesttemperatur von vorzugsweise etwa 38° eingestellt. Dieser Thermostat schließt bei einer Unterschreitung dies« Mindesttemperatur die Umgehungsleitung und unterbricht üb« das Relais, das dann anzieht, die Stromversorgung der Umlauf]pumpe.This additional boiler thermostat can reliably ensure in such a control that the temperature - regardless of the activity of the other thermostats - does not drop below a minimum level below which condensate formation and, accordingly, corrosive damage to the heat exchanger should be expected. 20 For this purpose, the additional boiler water thermostat is set to a target minimum temperature of approximately 38 °, which prevents condensation in the heat exchanger. This thermostat closes when the "minimum temperature falls below the bypass line and interrupts" the relay, which then picks up the power supply to the circulation pump.
In Ausgestaltung der Erfindung wird vorgeschlagen, daß die üb« den Antrieb d« Umlaufpumpe geführte 25 Zweigleitung von einem zwischen dem Verzweigungspunkt der Versorgungsleitung, in dem die Umgehungsleitung von d« Versorgungsleitung ausgeht und dem vom Heizkesselthermostaten betätigten Schaltkontakt gelegenen V«zweigungspunktder Versorgungsleitung ausgeht. Hierdurch isterreicht, daß diePumpevon der Regelabweichung des Raumthermostaten unabhängig ist und durchläuftIn an embodiment of the invention it is proposed that the branch line routed via the drive d circulation pump starts from a branch point of the supply line located between the branching point of the supply line, in which the bypass line starts from the supply line and the switching contact actuated by the boiler thermostat. This ensures that the pump is independent of the control deviation of the room thermostat and runs
In alternativer Ausgestaltung ist vorgeschlagen, daß die über den Antrieb der Umlaufpumpe geführte Zweigleitung 30 von einem zwischen dem Schaltkontakt des Raumthermostaten und dem vom Heizkesselthermostaten betätigten Schaltkontakt gelegenen Verzweigungspunkt d« Versorgungsleitung ausgeht. Bei dieser Schaltung tritt der Vorteil auf, daß bei einem Zurückgehen d« Raumtemperaturregelabweichung die Umwälzpumpe vom Raumthermostaten zusammen mit dem Biennstoffventil des Kessels vom speisenden Netz getrennt wird. Damit taktet die Pumpe, was zu einem geringeren Verbrauch an elektrisch« En«gie führt. 35 In weiter« alternativ« Ausgestaltung wird vorgeschlagen, daß die üb« den Antrieb der Umlaufpumpe geführteIn an alternative embodiment it is proposed that the branch line 30 guided via the drive of the circulation pump starts from a branching point d «supply line located between the switching contact of the room thermostat and the switching contact actuated by the boiler thermostat. The advantage of this circuit is that if the room temperature control deviation decreases, the circulating pump is disconnected from the room thermostat together with the biennial valve of the boiler from the supply network. The pump thus clocks, which leads to a lower consumption of electrical energy. 35 In a further “alternative” embodiment it is proposed that the drive of the circulation pump be guided
Zweigleitung von einem zwischen dem vom Heizkesselthermostaten betätigten Schaltkontakt und der das Magnetventil betätigenden Spule gelegenen Verzweigungspunkt der Versorgungsleitung ausgeht. Bei dieser Ausgestaltung ist die Pumpe vom Vorlaufth«mostaten und seiner Regelabweichung beherrscht, so daß beim Ausregeln der Regelabweichung des Vorlaufthermostaten neben dem Heizkessel auch die Pumpe vom speisenden Netz getrennt wird. 40 Damit ist der Verbrauch an elektrischer Energie noch geringer.Branch line starts from a branching point of the supply line located between the switching contact actuated by the boiler thermostat and the coil actuating the solenoid valve. In this embodiment, the pump is controlled by the flow thermostat and its control deviation, so that when the control deviation of the flow thermostat is corrected, the pump is separated from the supply network in addition to the boiler. 40 This means that the consumption of electrical energy is even lower.
