Connect the plug X1 to X4 to the appropriate contact–points on the heating electronics. The brown 3–
pole plug must be connected to the control 812 / 806. To do this, it is necessary to take off the metal
safety plate above the plug at the back of the control panel.
The consumer is connected according to the following table. The connections mixer 2 and pump mixer
2 are only used for two mixed heating circuits when a E233B is inserted.
Only 806: So that the control panel 806 can recognize the burner contact of the heating electronics, the
contact–points 1 and 2 of the connection box must be connected to the contact–points 3 and 4 (weather–
influenced heating electronics) with a cable fitted by client at the bottom 10–pole–feeler plug of the
control panel 806.
