Explanations
Priority of DHW heating over the heating circuit
Note
If several heating circuits are connected, only adjusta-
ble in conjunction with low loss header.
0 Without DHW heating priority
1 With DHW heating priority
Explanations
The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
heating circuit (heating curve). Operation with room
temperature hook-up must be set for the heating cir-
cuit (parameter 933.6). Only change the value for sys-
tems with one heating circuit.
For a sample calculation, see chapter "Heating curve"
