A previous thread here a few weeks ago pointed out that "aux" heat and "emergency" heat, while both supplied by the same mechanism, mean different things.
If your thermostat shows that "aux" heat is on, it means the heat pump is doing what it can but that the coils are on to supplement the heat pump itself. This would be normal operation in very cold weather ("very cold" depending on your heat pump).
If your thermostat shows "emergency heat," it means that the coils are on because the heat pump is not working and needs repaired.
