Pump capacity diagrams, heating medium
side
To set the correct flow in the climate system the correct
speed must be set for the heating medium pump in the
different operating conditions.
The flow must have a suitable temperature difference for
the operation (heating operation: 5 - 10 °C, hot water
regeneration: 8 - 10 °C, pool heating: approx. 15 °C)
between flow temperature (BT2) and the return temper-
ature (BT3). Check these temperatures in menu 3.1
"service info" and adjust the heating medium pump (GP1)
speed until the temperature difference is achieved. A high
difference indicates a low heating medium flow and a
low difference indicates a high heating medium flow.
Set the speed of the heating medium pump in menu
5.1.11, see page 59.
Read off what speed the heating medium pump should
be from the diagrams below.
