    Hi, thank you very much for your answer.
    The link is for the instalation guide, which I have.
    I already connected the wires as the letters on the guide but the cooling does not work.
    I didn't conect the white wire, does this matters?
    Any help will be highly appreciated.
    Thanks

    You have to connect the white wire. You may note at the beginning of this board there are sticky notes and they have much information on Thermostat replacement. You might check there for more answers.
