DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with small
children, disabled, or
elderly persons may require
a 120°F or lower thermostat
setting to prevent contact
with HOT water.
Water Temperature Set Point
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heater’s
thermostat(s). The lower the temperature
setting, the greater the savings in energy
and operating costs.
To comply with safety regulations the
electronic control is factory programmed
at 120°F or less where local codes require.
This is the recommended starting point.
Water temperatures above 125°F can
cause severe burns or death from scalding.
Be sure to read and follow the warnings
outlined in this manual and on the label
on the water heater. This label is located
on the water heater above the lower access
panel.
Mixing valves are recommended for
reducing point of use water temperature
by mixing hot and cold water in branch
water lines. It is recommended that a
mixing valve complying with the Standard
for Temperature Actuated Mixing Valves
for Hot Water Distribution Systems, ASSE
1017 be installed. See page 4 for more
details and contact a licensed plumber or
the local plumbing authority for further
information.
The electronic control allows the water
temperature to be set from 110°F to 150°F.
The Performance Platinum residential
electric water heater has three modes of
operation.
They are:
Vacation mode:
Sets the temperature setting to a pre-
determined lower thermostat setting. The
water heater remains in this mode until
manually changed to Energy Saver or
Performance mode.
Energy Saver:
In this mode, the set point is limited
to 130°F. If there is no demand cycle
for the upper or lower element, the set
point is decreased periodically while still
keeping usable hot water in the tank. This
helps conserve energy while providing
usable hot water. The set point reverts
to the previous user setting if the water
temperature drops too low.
Performance:
This is the default mode of the
Performance Platinum residential electric
water heater. The control utilizes the two
temperature sensors to determine the
demand for heat and satisfies it with the
use of appropriate element. The set point
remains what was selected by the user.
Refer to "Programming the Electronic
Control Instructions" on page 14 for more
information.
