ERV in non-conditioned space?

All HRV/ERV instructions say to install in conditioned space, but finding a conditioned location for an ERV in a retrofit can be difficult-to-impossible. What are the implications of installing a residential ERV (eg, Panasonic FV-10VE1) in an unconditioned space (attic) in a mild climate like SF Bay Area? Just a little lower efficiency?

    Can't think of why they would have to be in a conditioned space except if transferring air below freezing temps moisture can collect on the wheel.

    San Fran, don't think you have to worry about that.

    Someone that knows more than me will chime in
