    I have project in which i have to create a soultion which will mantain the temperature of a living space with a volume of 400m3 between 25-30 degrees centigrade.

    I can use the following components

    lm358 Operational amplifer
    3 X lm311 compararators
    74ls32 Quad OR Gate
    74ls04 Hew NOT Gate
