Device for controlling heating boilers
First Claim
1. A device for controlling a boiler in a heating plant wherein the boiler has means for heating a heat carrying medium present in the boiler and circulating out thereof in the heating plant as well as means adapted to detect the temperature of the heat carrying medium present in the boiler and send signals to the heating means to start and stop the heating of the medium when a first lower temperature level is reached and a second higher temperature level is reached, respectively by the medium in the boiler, said device comprising delay means havinga first time measuring member arranged to measure a time signal representing the time between the temperature of the heat carrying medium reaching the second higher temperature level and the temperature of the heat carrying medium reaching the first lower temperature level following thereupon, andprocessor means for determining a delay time signal as a function of the time signal and to generate as a function of the delay time signal, a start signal for starting said heating means at a time delayed from when the first temperature, level is reached by the medium.
