TEMPERATURE SETTINGS ON THE PCB
(WITHOUT CONTROLLER)
There are 2 preset temperatures, 120 °F (50 °C) and 140 °F (60 °C), that you can select from by changing
the DIP switch settings on the computer board without the controller. See the table below.
When the controller is in normal operation, the set temperature of the controller is given priority over the
set temperature of the DIP switch settings.
NOTE:
The black square indicates the position of the DIP switch for set
temperature. For the 110C and 310C, only adjust DIP switch No. 9. For the
510C, only adjust DIP switch No. 5 on the lower bank. Do not adjust the other
DIP switches for temperature adjustment.
WARNING
•
DO NOT adjust the upper bank of DIP switches for the 510C model.
•
Turn off the power supply to the water heater before changing the DIP switch
settings.
•
The temperature has been preset at the factory to 120 °F (50 °C).
