Method of controlling a variable delivery pump (2) fitted to a heating system (1) comprising:
- a heat exchanger (3) connected to two circuits of fluids (4, 5), said variable delivery pump (2) making it possible to vary the flow-rate of the first fluid inside the heat exchanger (3);
- a return loop (6) on the primary circuit (4) allowing the first fluid reaching the input (7) of the heat exchanger (3) to mix with a portion of the first fluid coming from the output (8) of the exchanger (3);
- a first temperature sensor S1 measuring a temperature T1 of the second fluid coming from the secondary circuit (5);
- a second temperature sensor S3 measuring a temperature T3 of the first fluid coming from a primary circuit (4);
- a control unit (9) electrically connected to said first and second temperature sensors S1, S3, said sensors S1, S3 generating electrical signals as functions of the temperatures T1 and T3 and constituting electrical input signals of the control unit (9). |
