The only parameter that needs to be filled in on the parallel production is the "Heat Flow on the primary circuit". This can be filled in with a specific heat flow or a power percentage.
On the example below is an installation with an equivalent radiator capacity of 200 kW, on the parallel production you can indicate how much power goes to each boiler. There are two boilers one of 80 kW and another one of 120 kW.
The boiler of 120 kW is connected to the primary circuit of the parallel production therefore you need to fill in 120 kW on parallel production for the primary circuit.
On left-hand example is a heat flow of 120kW filled in on the "primary circuit", therefore the bottom boiler takes up 120 kW. On right-hand example is a heat flow of 120 kW filled in, but also a power percentage. As you can see on de example the power propagated on the primary circuit is 20% of 200 kW. This shows that filling in the power percentage has a priority over the filled in heat flow on the primary circuit.
