The Vitola 200 boiler does not have a boiler-mounted pump junction box.
When the Vitotronic, KK10 control is used with the DHW pump module, the factory default
setting will allow the space heating pump and the DHW pump to turn off when the boiler
water temperature is below the minimum boiler temperature setpoint. This function is
disabled when the S1.6 DIP switch setting is changed from the OFF position to the ON
position (upward movement of the DIP switch).
Minimum Temperature Setpoint Adjustment
The minimum boiler water temperature setpoint can be adjusted to a higher boiler
water temperature. This may be useful in applications using high temperature
heating circuits.
To determine whether an increase in minimum boiler water temperature setpoint is
recommended for your application, read the following information.

To adjust the minimum temperature for the Vitotronic, KK10 control, turn the
pump aquastat up or down. Use one of the following guidelines when modifying
the temperature as desired:
-Refer to Fig. 1 on the left.
-Use scale inside the control.
When the control is opened, the aquastat is located at the front of the control. The
vintage of the control will dictate the presence of an aquastat label
(see Fig. 2). If no label is present, look for the end shaft as illustrated in Fig. 1.
