    So what happens in heat mode and the switch fails?

    We break Y to the condenser only.

    Union or Non?

    Good Point. But I was thinking A/C only units. Around here most attic AHs are A/C only,with Basement Boilers for Heat & Domestic HW.

    Non, we are required to break R through safety switches. 90% gas included and I disagree. Humidifiers not required to have safety drain pans or be inside drain pan under furnace and I disagree too.
