Parameter group internal hydraulics
730D 3-way diverter valve mode
If, on site, only one pump and one three-
way diverter valve are used to switch
between DHW heating and central heat-
ing mode, parameter "Heating/DHW
diverter valve 730D" must be changed
to "1".
Valu Explanation
e
"0" Three-way diverter valve is not
installed; DHW is heated via a
separate output; secondary
pump does not run; circulation
pump for cylinder heating (heat-
ing water side) is started.
"1" Three-way diverter valve is instal-
led; secondary pump also runs for
DHW heating.

730C Set flow temperature, external demand

"Set flow temperature, external demand 730C"
Set flow temperature in case of external
demand, e.g. from the swimming pool
(see page 182).
In contrast to room temperature-depend-
ent or weather-compensated set flow
temperatures, a fixed set flow tempera-
ture is selected here, for example for
heating circuits.
