We need not assemble the pump P2 which serves for the hot water. The parametar which
determines the type of hydro installation inside the automation system is P37 and for this hydro
scheme is P37 set to 5.
If we want to use automation to keep the process and the puffer warming up through the
appropriate pump, then the hydraulic scheme should be as shown in figure 13. The point of
probe measuring for water temperature in the puffer is marked with S2.
In order to run operation of automation properly for the hydraulic connection and with the, then
it is necessary to adjust the parameter P37 onto the value 4.
If we want the automation to keep the process of heating the sanitary water through the
appropriate pump, then the hydraulic scheme should be as in figure 14.
In order the automation system should keep the operation of that pump for heating the boiler
with sanitary water, then it is necessary to adjust the parameter 37 onto the value 3.
