MANUAL MODE
The most basic operation of the Intelligent water heater ther-
mostat is the Manual Mode. With this mode the thermostat is
set at a desired temperature and the water heater operates to
maintain that temperature. The Intelligent Maytag water heater
utilizes a special sensing device in the control system that allows
for temperature accuracy to be maintained at plus or minus 1°F.
V
ACATION MODE
Vacation mode is used whenever the residency is unoccupied for
a considerable length of time (2-days or longer) and hot water is
not needed. By selecting the V
acation Mode
the water heater
will maintain a reduced setting of 80 degrees until a new opera-
tion mode is selected.
PROGRAMMABLE MODE
The Auto mode selection permits the water heater to be pro-
grammed for four periods a day, 24-hours a day and 7-days a
week. To begin programming, depress the “MODE” button
until the AUTO selection appears in the display. To activate
the Program Mode depress the “PROGRAM button at the
top of panel. The programming mode should appear as the
next display.
The first period to program is Monday “Morn” - this period is
designated as “Morn”. By depressing the + or - of the “TIME
button, the owner can choose the target time for the water to be
at a specific temperature. The heating elements will be activated
15 minutes before the target time to heat the water to the
desired temperature. For example, if 6:00 AM is the time the
occupant desires 130°F water for bathing, the time on the pro-
grammed display would be set for 6:00 AM. The next selection
to program is the desired water temperature to have for morning
activities. In this example the temperature would be set to 130°F
by depressing either the up ( ) arrow or the down ( ) arrow,
located next to the display panel, until the target temperature is
displayed.
The second period to program is Monday “Day” - the method
of setting the time and temperature are the same for all four
selected periods of the day. The second period designated “Day
can be set to a reduced temperature (70°F or lower) due to the
lack of need for hot water, assuming no one is at home during
the day. If everyone leaves at 9:30 AM, this time can be entered
into the program and the heating elements would not activate
until the temperature in the tank dropped to 70°F.
The third period to program is Monday “Eve” - this period is
designated “Ev
e
would usually begin when people arrive home
from their daily activities. The temperature for this period can
be adjusted to a normal hot water setting considering evening
demand like washing dishes or clothes. For example if 125°F is
the chosen temperature to have at 5:30 PM then these settings
would be entered into the program.
T
he fourth period to program is Monday “Nite
- this period
is designated “Nite” and is usually the beginning of decreased
hot water needs as the residents retire for the night. In the
example the temperature would be set for 70°F or lower with
the begin time set at 11:00 PM.
Program Copy - The first day of programming has now been
completed. If each succeeding day of the workweek requires the
same desired settings as those just programmed for Monday,
these settings can be copied to the remaining four days of the
week by depressing and holding the “PROGRAM” button for
several seconds. In this manner the first day’s settings are
repeated to all four remaining weekdays.
W
eekend pr
ogramming
- the weekend programming can be
set different than the weekday settings, if desired. Saturday and
Sunday can be separately programmed by advancing the pro-
gram selection to the day marked “SA” and/or “SU”. The steps
described above for programming the four periods per day can
be repeated for the weekend only using different times and tem-
peratures to provide desired water temperatures when needed on
the weekend.
