Check
•
To prevent scalding :
Hot Water Heater temperatures over 125°F
(52°C) can cause severe burns instantly or
death from scalding.
• Children, disabled and elderly are at the
highest risk of being scalded. Feel water
temperature before bathing or showering.
Temperature limiting valves are available,
consult with installer.
• When setting the Water Heater to 125°F
(55°C in °C mode) or higher, “Hi temp” will
blink for 10 seconds and emit a tone as a high
temperature warning.
• Take caution when using the Water Heater
again after setting to 125°F (52°C) or higher.
Always check the set temperature before use.
• Do not allow anyone to change the water
temperature while hot water is running.
DANGER
Operation
• The Power indicator is displayed.
• The previously set hot water supply
temperature is shown.
• The setting temperature displayed may vary
from the actual temperature at the fixture
depending on conditions such as season or
length of piping.
[For systems with recirculation operation]
• If you set the
Power
button to ON,
recirculation operation is automatically
started. (If “Synchro ON/OFF” was set to ON.
(See page 14))
• Turn off hot water, the symbol disappears.
• During recirculation, the symbol may be
continuously displayed.
(e.g. 110°F)
If “System

Temperature
2. Set the temperature using the / buttons
inside the cover.
Operation
• The Power indicator is displayed.
• The previously set hot water supply
temperature is shown.
NOTE
• Hot water temperatures shown
are approximate and may differ
from the actual temperature at
the fixture depending on external
factors such as the season and
length of piping in the system.
• When low temperatures are set
(for washing dishes, etc.), if the
incoming water temperature
is already quite high, it may be
difficult to ensure the outgoing
water temperature is as per the
setting.
• Check the temperature displayed
before using any hot water.
Be especially careful using hot
water after the set temperature
has been changed.
• When the hot water temperature
is adjusted using thermostatic
water mixing valves, set the
temperature on the Remote
Controller approximately 20°F
(10°C) higher than the required
temperature to ensure the
appropriate fixture temperature.
• For most residential applications,
the recommended setting
temperature is 120°F (50°C in °C
mode) or less.
