100%, or can be less than 100% if historical data shows the amount of makeup water used. If a second RTD is
not used, set to 0%. When 0% is selected, the energy calculation represents the outgoing energy only (no return
energy is subtracted).
Note: The meter ships from the factory assuming 0% return and has a 1000 ohm resistor installed in the RTD #2
wiring location. This needs to be removed if the meter is to be used in a manner other than with 0% return and
with the customer-supplied RTD in its place.
