Electric Energy Consumption of the Pump

The electrical power of a fixed speed pump (input PumpConfig = 1) is equal to its nominal power PMP-06.

The electrical power of a variable speed pump (input PumpConfig = 2) is proportional the pump speed to the power of three and equal to (SolPumpCtrl/100)3 * PMP-06. At 100 % pump speed the power is equal to the nominal power.

The electric energy of the pump is the integral of the electric power. The macro makes an update of the electrical energy every minute.

For a fixed speed pump the macro adds the value PMP-06 /60 every minute to the calculated electric energy.

In case of a variable speed pump we integrate the signal (SolPumpCtrl/100)3 * PMP-06/ 60 and refresh it every minute.


The value of the electric energy of the pump is displayed at the output “ElectrEnergyPmp” and in the parameter INI-02, which can also be used to update the consumed values after a new controller start.
