TEMPERATURE ADJUSTMENT (24V CONTROL SYSTEM)
The water heater temperature setting is adjusted by using the control display mounted to the front of the water heater.
The water heater thermostat is set at the lowest setpoint of 70F when shipped from the factory. The control display
shows the temperature setpoint in degrees Fahrenheit (F) or degrees Celsius (C), and the status of the water heater
("Idle" or "Heating"). If the water heater is functioning normally, the display will also show "Operational".
For energy efficient operation of your water heater, the suggested initial temperature setting is 120F (49
winter season, or any cold period, you may desire a higher temperature setting to adjust for the colder incoming water.
This adjustment, however, may cause additional condensation to form on the cooler tank surface. This does not mean
the tank is leaking. During summer months, the warmer incoming water temperatures will benefit the performance of your
water heater and reduce the amount of condensation developed.
Condensation does not mean your tank is leaking. Over 40% of reported tank leaks on installation are proven to be
condensation. To avoid unnecessary expense and inconvenience, make sure the tank is leaking before calling a service
person.
If the water heater display does not show "Operational" in the "Status" indicator, there may be an operating
malfunction with the water heater. If this is the case, a numeric code will be displayed. Refer to the label next to the
display for the definition of the error code and call your plumbing professional or service agent to service the water
heater. Do not try to reset the water heater without having a qualified service person to diagnose and correct the
problem. If the display is blank or does not show an error code, make sure there is power to the water heater.
Setting the water temperature to the maximum set point can result in scalding hot water delivered to the faucets. It
is highly recommended that the maximum setpoint be adjusted to the lowest temperature possible for the needs of
the installation. See following section to change the maximum setpoint limit (max setpoint).
heater control display is not in a public area that can result in the temperature settings being improperly adjusted.
See previous warning on scalds and an ASSE approved mixing valve.
When the maximum setpoint is reached, the display will show "Max Setpoint" without the setpoint value. The
maximum setting is equal to approximately 180˚F (82˚C).
The default temperature setpoint from the factory is 70˚F (21˚C).
