H2 pump Q18
Pump H2 can be used for an additional consumer. Together with an external demand
for heat at input H1, it is possible to serve an air heater or similar.
system pump Q14
The connected pump serves as a system pump for supplying heat to other consumers.
The system pump is put into operation as soon as one of the consumers calls for heat.
If there is no demand for heat, the pump will be deactivated followed by overrun.
