How to recenter the rift/head position vr template

How can I recenter the rift? I use the First Person Template v0.4.4 and when i put the camera further away(ca. 1.5m) on the wall and start my level the camera is offset but it worked well when it is near top of the monitor 60cm.

I'm looking for a button combo like in Alien Isolation where you push LB/RB
