The following code was suggested by K. Hamilton and tested by A. Tanasijcuz.

if(running scales.eq.1) then
    muref=sqrt(dotp(kn_pborm(0,3),kn_pborn(0,3)))
elseif(runningscales.eq.2) then
    muref=ph_Hmass
    if(flg_btildepart.eq.'r') then
      pt2=kn_preal(1,4)**2+kn_preal(2,4)**2
      muref=sqrt(pt2+ph_Hmass**2)
    endif
else 
   muref=ph_Hmass
endif

after this modification use:

runningscale 2
btlscalereal 1

in the Powheg config file.
