5.1.4 

Installing and connecting the VR 71 module 

The VR 71 accessory may be required depending on the design of the heating installa-
tion. It is installed close to the components in the installation using the fastening mate-
rial provided. 
 

5.1.4.1  Terminal assignment for the VR 71 module 

 

 

VR 71 printed circuit board 

 

 
On contacts "S12" and "S13", "I" stands for Input and "O" for Output.

 

On  outputs  "R7/8",  "R9/10"  and  "R11/12",  "1"  stands  for  Open  and  "2"  for 
Closed. 

 

Since the VR 71 is used as a source of power for the eBUS, 

it is necessary

 to 

ensure  that  the  polarity  for  the  eBUS  connection  between  the  heat  generator 
and VR 71 is correct ("+" at "+" and "-" at "-").
