    Refcomp inverter controls



    Please help me out with understanding analog outputs from Carell controller:
    Y1 is going out to EXV driver
    Y2 is the demand signal to Refcomp inverter
    Y3 is the demand signal to condenser fan motors inverter

    Not sure what is the function of Y1 signal here.
    Anyone has any suggestions?

    Thank you

    I would assume that it is the setting signal to the EEV.
