Enter a temperature higher
than the buffer tank set point,
otherwise the buffer tank
temperature will be limited by
this parameter.
9.2.11 Configuring and using the CB04 auto-filling option kit
The CB04 auto-filling option kit is used to fill the heating circuits or to
maintain the optimal pressure in the heating circuits, without human
intervention. After having followed the instructions for assembly of the
option kit, simply configure a few parameters to automatically obtain or
maintain an optimal pressure. The heat pump does not start up during the
auto-filling phase.
