Temperature Setting DIP Switch Adjustment

Required adjustment for up to 140°F (60°C) water temperature settings

!WARNING: Refer to scald potential warnings on page 4 before making adjustment. Changing this setting is done at your own risk.

DO NOT alter the #4 DIP Switch if the setting of up to 140°F (60°C) is not required.

Follow the instructions below if it is determined that a setting of up to 140°F (60°C) is required.

●Turn off remote control. Turn off the gas and water shutoff valves.

●Remove the front cover.

●Find the DIP Switch #4 located at the top left hand side of the PCB. (See diagram to the right for DIP Switch location).

●Change the DIP Switch #4 setting to the “ON” position. DO NOT alter any other DIP Switch. The LED on the PCB is flashing. At the same time, the display of the Main Remote Control starts to flash.

●Press the “SW1” button on the left hand side of the PCB for more than 1 second. The LED on the PCB starts illuminating continuously. At the same time, the display of the Main Remote Control is on continuously.

●Change the DIP Switch #4 setting back to the “OFF” position. DO NOT alter any other DIP Switch. The LED on the PCB will stop illuminating. At the same time, the display of the Main Remote Control will turn off.
