Operating modes

This water heater defaults to the Auto operating mode.
The Auto mode is the recommended setting for this
water heater, but can be changed if desired.
Economic Mode
Economic is the the most energy-efficient mode for this
water heater. It takes heat from the surrounding air to
heat the water. The time it takes to heat the water is
longer in this mode, so it may NOT be sufficient if you
have a high-demand situation such as a large
household.
Electric Mode
This mode uses only the upper and lower heating resist-
ance elements to heat the water. The time it takes to
heat the water is less in this mode, but it is the LEAST
energy-efficient mode.
Auto Mode (recomended mode)
Auto mode combines the energy efficiency of Economic
with the recovery speed and power of the Electric
mode, with normal water usage.
