Temperaturüberwachung

Anlagendrucküberwachung

Trockenbrandschutz

Das Gerät verfügt über einen Drucksensor, der den Betriebsdruck im Heizkreis

überwacht. Sinkt der Systemdruck unter 0,8bar, erscheint am Display ein Warn-

hinweis. Sinkt der Systemdruck unter 0,5bar, führt dies zum Abschalten des Bren-

ners, ohne dass dieser das Gerät verriegelt. Wird der Druck wieder über die Auss-

chaltschwelle erhöht, geht das Gerät selbstständig in Betrieb.

Das Gerät überwacht zudem bei jedem NETZ EIN den Wasserdruckanstieg im Sys-

tem. Wird bei Pumpenanlauf kein Druckanstieg von mindestens 150mbar festgestellt

geht das Gerät nicht in Betrieb. Es kommt zu einer verriegelnden Störung

Fehler-

code 107, d.h. Gerät trocken.

Brennkammertemperaturfühler (eSTB)

Der Brennkammerfühler ist ein Anlegefühler an der Rohrwendel. Er besteht aus 2

Fühlerperlen, die zusammen die Funktion eines Sicherheitstemperaturbegrenzers

(eSTB) erfüllen. Zugleich erfüllt der Brennkammertemperaturfühler die Funktion eines

Temperaturwächters (TW).

Die TW Abschalttemperatur liegt bei > 102°C. Diese führt zum Abschalten des Bren-

ners, ohne dass dieser das Gerät verriegelt. Störung

Fehlercode 06. Bei Unter-

schreiten des Abschaltpunktes geht das Gerät selbständig wieder in Betrieb.

Die TB- Abschalttemperatur liegt bei ≥ 108°C. Diese führt zum Abschalten des

Brenners und zu einer verriegelnden Störung

Fehlercode 02. Bei Unterschreiten

des Abschaltpunktes geht das Gerät, nachdem der Fehler quittiert wurde wieder in

Betrieb.

Kesseltemperaturfühler (Regelfühler)

Der Kesseltemperaturfühler im Vorlaufrohr vor dem 3-Wege-Ventil wird als Regel-

fühler eingesetzt. Das Gerät wird über die hier ermittelte Temperatur geregelt.

Die maximal mögliche Kesseltemperatur beträgt 85°C (Werkseinstellung). Wird diese

Temperatur überschritten, führt dies zum Abschalten des Gerätes und zu einer Bren-

nertaktsperre (Werkseinstellung 7 min.).

Abgastemperaturfühler

Der Abgastemperaturfühler schaltet das Gerät bei einer Abgastemperatur > 110°C

ab. Es kommt zu einer verriegelnden Störung

Fehlercode 07.

Die Abgastemperatur wird über einen Fühler in der Kondensatwanne ermittelt.

Brennkammerdeckel- STB (Thermostat)

Der STB schaltet das Gerät bei einer Temperatur > 185°C ab. Es kommt zu einer

verriegelnden Störung

Fehlercode 01.
