You most likely have a heat pump, the aux heat (usually electric) comes on anytime the room temperature is 4 degrees below the thermostat setting. Does the buzz go off when the aux heat lite goes out? If the aux heat does not shut off then the primary heater (heat pump) is not putting out enough heat to satisfy the thermostat. I need a little more info. Do you have a heat pump? Is it working?

Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

SOURCE: Thermostat show AUX HEAT
A heatpump has two sources of heat. One is when the heatpump is operating in normal heat mode, and the other is typically electric heat strips.
The strips come on when the unit is going into defrost, when the unit is not able to keep up with the demand for heat (really cold temps) and when the unit is not working properly.
Whne the strips are on, the T-stat displays "aux-heat" to indicate the strips are in operation.
If the strips are working properly you should have warmer air than with the HP alone. Try switchin it from "heat" to "emergency heat" and see what it will do.
When the HP is not able to keep up with the demand for heat then the heat strips come on, but they typically come on only when the room temp has gotten well below the thermostat setting.
In that situation it would be normal to see indoor temps at 63 degrees when the T-stat is set on 70.
But when you set it to E-heat it bypasses the heatpump operation and goes directly to the heat strips. If they are working properly it should maintain an accurate temp in the home.

I set the thermostat for 70 degrees. It comes on always in auxillary heat and does not shut off when it reaches 70 degrees. It is a heat pump, I am assuming, it might be the thermostat? But when the air conditioner is on, it turns off when it reaches it's temperature.

The aux switch is for electric heat banks installed in the air handler. Depending on the outside temp. it may not be efficient to run in heat pump mode but in aux. or emergency would run the electric heat in the air handler.
