Water flow (l/s)
Setting the temperature differential
For external control, a circulation pump is installed so that the right flow through the
heat pump can be guaranteed.
Set the right temperature differential by adjusting the speed of the circulation pump.
This is to ensure that the right differential for the current outdoor temperature is produced
according to the table.

In some systems with EcoLogic, the entire radiator flow must go through the heat
pump, so the pump must be sized according to the flow of the whole system.
To ensure safe operation, EcoAir 510 should have a flow rate no less than 760 l/h.
This provides a temperature differential of approx. 7 °C for an outside temperature
of +7 °C and a primary flow temperature of 35 °C at a minimum flow of 0.21 l/s.
