Abstract
The invention relates to a pump assembly with a pump and with an electrical drive motor, as well as an electronic control device. The electronic control device includes a rotation direction recognition module for recognizing the correct rotation direction (CW, CCW) of the drive motor and of the pump. The rotation direction recognition module detects at least one performance characteristic value (H, Q, P) of the pump assembly, and is designed in a manner such that on rotation of the drive motor, the rotation direction recognition module detects at least one performance characteristic value (H, Q, P) and determines the correct rotation direction (CW, CCW) by way of evaluation of the performance characteristic value (H, Q, P).
