    Wiring help trying to install a Lyric T5

    The old thermostat has the wires labeled differently as the new one. Any thoughts on how to correctly install it?

    Thanks.

    Trying to replace a Robertshaw 300-208 with a Lyric T5. My current wiring as follow : Wire color / Terminal
    White/W1
    Yellow /Y1
    Green /G
    Red /R
    Black/24VAC
    Orange/O
    Bleu /LED2
