When should I select Emergency Heat?
If your heat pump is not adequately providing heat, you can bypass it by selecting Emergency (heat) until the heat pump can be
serviced. In some installations, your thermostat may indicate a problem with the heat pump by displaying a message (on the main
screen) underneath the temperature. You may also want to select Emergency (heat) when the outdoor temperature drops below
freezing since the heat pump is very inefficient at low temperatures.
See Balance Points (page 22) for other options.
