I have a heat pump in North Carolina and I have the nest 3rd generation thermostat. It's my understanding that the white wire is for aux heat and can be put into either the W1 or W2 position. I don't want the aux heat to come on at all so I've disconnected the white wire. After I did this I tested the system to make sure it still produced heat and it does. My question is - will disconnecting the white wire hurt my system?
