Do you have a question about the Pro 3000 Series and is the answer not in the manual?
Questions and answers
when should the Emergency switch be used and with which **** setting?
The Emergency Heat (em Heat) switch on the Honeywell Pro 3000 Series thermostat should be used only when your heat pump is not functioning or cannot efficiently heat your home. In this mode, the compressor is locked out, and the auxiliary heating system (e.g., electric or gas furnace) is used instead. This setting should be selected specifically for heat pumps with this capability.
