8 Operating the Water Heater
3.2 Adjusting the Water Temperature
WARNING
Before adjusting the water temperature, read “To prevent
burns:” on page 4 carefully. Water above 120°F can cause
instant scalding, severe burns, or death.
The water heater is set to 120°F (49°C) by default. To adjust the
water temperature:
Make sure that all hot water faucets are closed, and ensure that 1.
the internal circulator and any external circulating pumps are
off.
Note
If a hot water faucet is open, you can adjust the
temperature only from 98-110°F (37-43°C).
Press the + (Up) or – (Down) buttons until the desired 2.
temperature appears on the display. You can adjust the
temperature while the display is flashing. Once the display
stops flashing, the temperature setting is stored.
Note
The water heater will retain your settings during
a power outage.
You can adjust the temperature by the below 10-degree
increments, depending on the temperature range:

must be set to “external recirculation” mode.
