Abstract
The combined gas-air control system for gas fired boilers (B) including a microcontroller ( mu C) with memory means, set point temperature selector means (Rh,Rs), measuring means (18,19,20,21), a thermostat (27), a variable-speed fan (6), a gas modulating valve (MV) in which the microcontroller ( mu C) comprises: first controlling means (22) for correcting the error signal E(T)=Trh-Th or E(T)=Trs-Ts and for controlling the air pressure in the combustion chamber (1), second controlling means (23) for correcting the error signal E(P)=Pac-Pa and for controlling the speed of the fan, processing means (24,25) for processing the ionisation voltage and the modulating valve current signals, third controlling means (26) for correcting the error signal E(V)=Vion(th)-Vion and the modulating valve current. <IMAGE>
