Buderus Indirect Hot water tank too hot

I recently had a Buderus G115 boiler installed, with a Buderus ST-150 40 gallon indirect hot water tank. The aquastat for the hot water tank is a Goldline SP-30D, one of the controls recommended by Buderus. The zone valve is a Taco 1 inch. The goal was to get 120 degree DHW. The DHW was running hot compared to the upper limit set on the aquastat, so we lowered the high temp to 105 degrees
