What is the EM HT (Emergency Heat) switch position on my heat pump thermostat?

The EM HT (Emergency Heat) feature allows the user to use a backup heat source when the heat pump is not working. The Emergency Heat feature locks out the heat pump compressor so that only backup heat is used. This is typically used until a heating and/or cooling contractor can troubleshoot or fix the heat pump system.
