Buderus Logamatic 2107 Installation And Service Instructions

Oil burners – factory jumper between terminals 12 & 10,
brings 120V from 12 to 10. When contacts close
between terminals 10 & 11, 120V power is sent from
terminal 11 to Hot on the burner (terminal 4 is the
neutral).
Gas burners – remove factory installed jumper between
terminals 10 & 12. The contacts between terminals 10 &
11 are now “dry” (no voltage present) and switching to
the burner is now low voltage between terminals 10 & 11
on the R2107 and TT (or RW) on the boiler aquastat.
