Control mode 1 – Loading control for heating circuit and hot-water
demand
System hydraulics

Heat generator
b
Buffer tank
Heating circuit and hot-water controls send their demand values
to buffer control. Buffer control demand additional energy from the
heat generator via the buffer loading pump.
See the table below for detailed correlations.
