Abstract
A method controls a circulation pump () in an installation with at least two circulation circuits (), with which the circulation pump () is integrated by way of a switch-over valve () into the one or the other circulation circuit (or) depending on the switched position. The pump () is activated differently depending on the switched position of the switch-over valve (). The switch-over procedure is detected by way of determining the pressure course and/or the flow rate course in the pump () or an electrical variable which is dependent thereon, of the motor driving the pump, and the pump () is operated in another manner accordingly.
