Installation Guide
DHW circuit, in general:
If the installation has a changeover valve (P2 / M3), also called
priority-valve, between the heating and the DHW circuits, the
changeover valve is activated at DHW heating demand. The
circulation pump (P1) is ON when heating the DHW.
Parallel mode in two-pump applications:
If the DHW heating temperature has a value close to the desired
flow temperature in the heating circuit, the circulation pump (P1) in
the heating circuit will not be switched OFF during DHW heating.
The return temperature (S5), when the DHW heating is active, can
be limited to a fixed value.
An anti-bacteria function is available for activation on selected
days of the week.
A367.1 only: The DHW circuit can be connected primarily and the
valve 'P2 / M3' operates as ON / OFF valve.
The DHW circulation pump (P3) has a week schedule for up to 3
ON-periods / day.
