Note
The maximum temperature that can be set in the Water
Heater Display is limited to the “Max Setpoint” described
previously. To change the “Max Setpoint”, refer to the
procedure “To Change the Maximum Setpoint Limit..."
described previously under “Accessing the Service Mode

adjusted to the lowest temperature possible for the
