Danke für Eure Antworten!
Ich habe allerdings festgestellt, dass bei meinem JC ein komplettes Schliessen des Ventils (im laufenden Betrieb und beim "Kaltstart" getestet) eine unmittelbare Fehlerabschaltung der Heizung bewirkt mit
Code "014" (= ... aufgrund Überhitzung durch Auslösen der Differenzauswertung abgeschaltet),
Code "030" (= ... Brennermotor EMK ausserhalb des zulässigen Bereichs) bzw.
Code "052" (= ... aufgrund eines fehlgeschlagenen Startversuchs abgeschaltet).
Also lasse ich besser das Ventil - wie von Linus empfohlen - ca. 1/4 geöffnet, auch wenn es dann noch ein wenig plätschert!
Beste Grüße

it could be a signal that the "normal " way of the flow is obstructed ; could be a four-way valves ( there is one valve for the bathroom and one valve for the living-room ) or the pump is too lazy...
On my JC , the valve is full closed from years...
this is the description about fault code 014 ( copy from eberspacher tech docs )
Difference between temperature values of overheat sensor and temperature sensor > 25K. The prerequisite for this fault code being indicated is that the HYDRONIC is in operation and that the water temperature at the overheat sensor is at least 80°C. • Check water circulation system:- check all hose connections for leaks- is a restrictor fitted in the water circulation system?- was attention paid to the correct direction of flow during installation of thermostat and check valve?- has the water circulation system been bled carefully?- check water pump for function • Check temperature sensor and overheat sensor and replace if necessary. See page 22 for reference values.
How more is the red valve open, how easy is the way for the flow of water , how less fault 014 occurs but ...how less energy ( = heat) flows in the convectors.
I do n't understand why codes 030 &052 are displayed: this is about the burning process without any connection with water flow ( code 014 )
