A. SAFETY CONTROL
 The heater has a high-limit control that is located on the top
of the tank. This surface mounted high-limit is designed to
interrupt the flow of electricity to all elements when it senses
dangerously high temperatures. If this switch operates, do
not attempt to reset. A dangerous situation is indicated and a
qualified service man should be called to find the source
before the unit is operated again.

Temperature of the water should be tested periodically at the
faucet to be sure temperature controllers are working
properly.
B. TEMPERATURE CONTROL
 To change the temperature set point for hot water output,
from the home screen, press the
AND buttons on the
controller. The display will flash the new temperature set
point as the
or buttons are pressed. Once the desired
temperature setting has been reached, allow the screen to
time out after about 5 seconds. The new setpoint can also be
saved by pressing the
AND buttons. Pressing will
cancel the changes without saving. The display will now
show the newly set temperature (e.g., “116”).
