WARNING
Never allow small children to use a hot water tap,
or to draw their own bath water. Never leave a
child or handicapped person unattended in a bath-
tub or shower.
WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a
temperature which will satisfy clothes washing,
dish washing, and other sanitizing needs can scald
and permanently injure you upon contact. Some
people are more likely to be permanently injured by
hot water than others. These include the elderly,
children, the infirm, or physically/mentally handi-
capped. If anyone using hot water in your home fits
into one of these groups or if there is a local code
or state law requiring a certain temperature water
at the hot water tap, then you must take special
precautions. In addition to using the lowest possi-
ble temperature setting that satisfies your hot
water needs, a means such as a mixing valve,
should be used at the hot water taps used by these
people or at the water heater. Mixing valves are
available at plumbing supply or hardware stores.
Follow manufacturers instructions for installation of
the valves.
Before programming the settings on the thermostat, read
the “Temperature Regulation” section again.
This new programmable thermostat technology makes it pos-
sible for you to enjoy all the benefits of hot water whenever
you need it and save the cost of heating water when you don’t
need it.
Simple and easy to use, the programmable control has three
basic modes of operation:
1. Manual mode – a set and forget operation.
2. Vacation mode – for those occasions when the residence
is unoccupied and there is no need for hot water.
3. Programmable mode – can be programmed for up to 24
hour a day, 7 days a week with 4 set periods a day.
Override is an optional setting that allows for temperature
adjustments during a given time period. This setting reverts
back to the previous mode of operation upon completion of
the designated override time period.
Option menu is a mode to change the factory setting for the
time clock (12 hr. clock or 24 hr. military), temperature scale
(°F to °C), default heating setpoint, vacation setpoint and
maximum heating setpoint.

TTING:
Your new programmable control comes complete with a day of
the week and digital clock display. These settings are changed
using the day and time keys on the control pad. To adjust day
and/or time, depress the appropriate key button. The day of the
week scrolls left to right on the display as the “DAY” button is
depressed. The time setting can be adjusted by scrolling for-
ward or backward using the + and - of the “TIME” button.
The clock is based on a 24-hour rolling display with AM and
PM appearing below the hour and minute characters.
CONSTANT TEMPERATURE DISPLAY:
The constant display screen shows the water temperature
“WATER TEMP” inside the tank. It is continually on dis-
play until interrupted by a reprogram procedure, but reappears
after 20 seconds of inactivity.
MODE CHANGE
To change the mode-of-operation depress the “MODE” but-
ton at the bottom of the control. The mode display will change
by scrolling from top to bottom with the Auto mode appearing
on the top of the column, followed by the Manual mode in the
middle and finally the Vacation mode at the bottom. Continue
to change between mode settings by depressing the “MODE”
button until the desired setting is displayed.
