TEMPERATURE SETTINGS ON THE PCB
(WITHOUT REMOTE CONTROLLER)
There are 2 preset temperatures (49 °C (120 °F) and 60 °C (140 °F)) that you can select from by changing
the DIPswitch settings on the computer board without the remote controller. See 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 DIPswitch settings.
Normal Operation
Owner's Guide
NOTE: Only change the switches with dark squares. The dark squares
indicate the direction the DIPswitches should be set to.
WARNING
• DO NOT adjust the upper bank of DIPswitches for the T-H3-DV / 540H.
• Turn off the power supply to the water heater before changing the DIPswitch
settings.
• The temperature has been preset at the factory to 49 °C (120 °F).
