-SETTING THE TEMPERATURE ON THE PCB-
(WITHOUT BUILT-IN CONTROLLER or REMOTE CONTROLLER)
There are two preset temperatures (120°F (50°C) and 140°F (60°C)) that you can select when the temperature con-
troller is inoperable. To do so, adjust the appropriate DIP switch as shown in the table below.
When the remote controller is in normal operation, the set temperature of the remote controller is given priority
over the set temperature of the DIP switch settings.
WARNING
• To set the temperature, adjust only the No. 5 DIP switch in the MIDDLE bank of
DIP switches. (See below.) DO NOT adjust the other DIP switches.
• Turn off the power supply to the water heater before changing the DIP switch
settings.
• Failure to observe these warnings could lead to carbon monoxide poisoning,
severe personal injury, or death.
