Installation Instructions 

for Control Center VR 65

5.1 

Installing the VR 65 with one 3-port valve

•  Wire up the Control Center as shown in fig. 5.2.
•  Connect the eBUS terminals of the VR 65 to the eBUS 

terminals of the heating appliance using a two-core 
cable. The polarity of the eBUS cable can be mixed. 
The eBUS can be branched at any part of the system.

The Control Center VR 65 requires its own 230 V mains 
supply via a switched fused spur.
The boiler also requires a 230 V supply.

  Note! 

The VR 65 has a mains switch (see fig. 4.2) to 
isolate the internal electronics as well as all 
connected zone valves for the purposes of tests 
and maintenance. When the housing cover has 
been removed, a green LED indicates if the 
VR 65 is still connected to the mains voltage.
