    I assume you are talking about your thermostat for the heat and a/c from your heat pump and e.m.h. is the Emergency Heat selection.

    I would change the category to Home & Garden/Maintenance to get an answer.

    In the meantime, you have likely blow a fuse at the Condenser Disconnet box, the outdoor unit of your heat/air system, which will have to be reset.
