<p>A system for controlling a heating plant comprising a boiler (2) inside of which there is a chamber for heating a liquid, a plurality of feed pipes (3) through which the hot liquid is fed into a plurality of radiators (4) and a plurality of return pipes (5) by means of which the radiator liquid is returned to the boiler. An environmental thermostat (6) is adapted to measuring the temperature of the environment. The system comprises a control unit, supplied directly by an electrical feed, and connected to the environmental thermostat (6) and the boiler (2), and connected in such a way that when the thermostat automatically starts-up the boiler, the control unit defines the boiler on and off times, in a variable manner depending on pre-set activation times.
