Indicator Lamps: There are 6 indicator lamps located on the unit control panel:
• Power (amber lamp): When lit, indicates power is applied to the unit.

and there is no remote control system attached.

target water temperature.

lamp is ON, service is required. Call the number shown in the CONTACT INFORMATION
