In addition to the digital temperature display, there are five indicator lights:
The POOL ON light indicates that the pool water temperature is governing operation of the heater.
The SPA ON light indicates that the spa water temperature is governing operation of the heater.
The HEATING light comes on and stays on when the burner is firing. This light should be on whenever the burner is on.
It blinks when the heater is calling for heat but not firing. If this light is on but the burner fails to come on, one of the
"service" lights should come on, indicating a fault in the system.
The SERVICE SYSTEM light indicates that there is insufficient water flow to the heater. If the pump is operating, this
usually indicates that the filter and/or skimmers should be cleaned (some filters may require back-washing). If the light
remains on after the filter/skimmers have been serviced, the system should be checked by a qualified service technician.
The SERVICE HEATER light indicates a fault in the heater or its controls. If this light comes on, shut down the heater
