The KS40-1 burner controller delivers high precision and low cost control on general-purpose, two - and three-stage stoves. The controller can provide digital volume on/off and continuous volume valve position output control signals, so that different fuels to achieve better control effect. The controller uses a general input signal channel to receive the process value input, so that the thermocouple, Pt100 thermal resistance signals used for temperature control, two -, three - wire or 20/30/50Ω pressure sensor signals used for boiler pressure control. The additional input channel INP2 can be used for example as an external set point or as a climate compensation signal.
