6.3.7.4. Geothermal HP Energy Tracking
Energy tracking for geothermal heat pumps requires the installation of an Entering
Water Temperature (EWT) sensor. See the geothermal heat pump literature for
information on installing this sensor.
If the EWT sensor is installed, the installer will be able to enter the Loop Flow Rate
and the Loop Pump power. See the figure in Section 6.3.7. These inputs will help
the Energy Tracking algorithm properly calculate geothermal heat pump usage. See
the geothermal heat pump literature for details.
If the EWT error message is shown, as illustrated in Section 6.3.7, that means that
the EWT sensor was installed and had valid readings at one time, but is now
malfunctioning. See the geothermal heat pump literature for details.
