DHW priority
With DHW priority, preference can be given to DHW storage tank
charging by reducing the amount of heat delivered to the heating
circuits.
No priority
During DHW heating, there is no restriction with regard to the amount
of heat delivered to the heating circuits.
The highest temperature request (space heating or DHW) is sent to
the heat demand controller.
Absolute priority
During DHW heating, the heating circuits are not allowed to draw any
heat.
The temperature request for DHW charging is sent to the heat de-
mand controller.

Absolute
In the case of DHW heating with a diverting valve, set the

is enabled when the DHW temperature drops below the DHW set-
point by the amount of the switching differential (1..20 K) set here.
Charging is stopped as soon as the DHW setpoint is reached again.
