Logamatic R2107 Issue

Newly installed G115 with R2107, Carlin Burner.  After installation learned hour meter did not register hours burner firing.  Learned needed to affix a jumper wire between terminal 8 & 11.  Did so and hour meter works fine.  Subsequently found that in manual mode adjustable aqua-stat would not shut off at set temperature and unit would fire until it reached high limit shutoff 230F.   Reviewed with Buderus Tech support and confirmed all wiring correct....  Has been escalated to next level back have not heard back from them and looking for resolution.  Anyone had similar problem, solution? Thanks!

    When using the manual option ... Everything will turn on, then you need to adjust boiler temp by the temperature knob.. if the logamatic is controlling the hot water .. the hot water will reach the same temp as the boiler set point
