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).
