Pump operating mode 2:
Buffer primary pump for BSP cylinder
The header sensor (buffer) only affects the heating operation. In
case of cylinder heating, the reference temperature is provided
by the internal boiler sensor. In heating mode, the buffer primary
pump runs only when there is a burner demand. Pump run-on in
accordance with parameter HG07.
Soft starting: At TK
Ist
< TK
min
(38 °C) buffer primary pump and
cylinder primary pump "OFF". MKP continues to run with soft
starting.
Note: Increase the pump run-on time from 3 min to 15 min.
Set the parameter HG13 to 7.
