Fig. 2-53_01_124
This menu
1
is only visible when a buffer control in the
boiler control is enabled.
In the event of good weather being forecast, the buffer
tank is charged for a shorter time within the time
release.
The bar
2
can be used to set the level of influence for
each buffer tank individually.
0% = if the burner has started and the buffer tank is
within a time release, the buffer tank is completely
charged. The charge request is fulfilled when the
buffer
temperature, lower,
has reached the
maximum buffer
temperature, lower
(in the buffer tank main menu).
100 % = if the burner has started and the buffer tank is
within a time release, the buffer tank is not completely
charged. The charge request is already fulfilled when
the
buffer temperature, lower,
has exceeded the
mini-
mum buffer temperature, upper
(in the buffer tank main
menu).
