During an emergency. i.e. when the heat pump is not working. If your heat pump can not keep your house warm, then the auxiliary heating coils (same thing as emergency heat) will come on automatically. If not, then there is a problem with your heating system.
On a system that uses a Heat pump, the heat setting utilizes the pump, and electrical coil heating as a backup. On the EM setting the heat pump won't run, only the axillary coils will provide heat.
what controls the heat pump to determine whether it is in the heating cycle or cooling cycle
Usually, you will notice diminished heating capacity from your system, and the out side temperature is dropping below the average temperature your heat-pump operates at. This is the time to activate your emergency heat.

Usually a backup heating unit. For instance in a heat pump when the temperature drops below the temperature where the heat pump cannot extract heat from the existing air electric heating elements kick in.
is it really run ning or is it possible that you have a heat pump system and it is the heating portion of the system operating?
