    The thermostat wire is too small or the run is too long.
    That is not "wall of shame" material.

    To small or too long for y1 but it's okay to wire y2 to y1 and the relay for y1?

    I was thinking isolation relay but what is the reason for the blue wire as it will not be isolated at that point.

    That was my first thought as well.

    Why is Y2(BL) going to Y1?
    I get the relay, but, Y2 on Y1, when it's a 2 stage unit....is confusing me?
    Even if they're twinned on the back of the TB, there'd be no need for blue?




    Actually, the relay doesn't make any sense either: If the signal coming back from the tstat is strong enough to energize the relay coil, then it would be strong enough to then activate the CC1 coil?
    UNLESS, there is an economizer?

    It probably was, until someone decided to jump the stages together, without thinking about what they were seeing. Is this a national account, by any chance?

    It could only be useful if you have 2 separate 24v power sources connected together. All you have to do if it's blowing fuses is swap common and hot at one transformer. Someone didn't know how to fix the real problem, but this "worked".....
