▲ TEMP Press this button to raise the temperature setting.
▼ TEMP Press this button to lower the temperature setting.
To toggle the display between degrees Centigrade (°C) and degrees Fahrenheit (°F):
1. Press the HEATER OFF button to switch the heater OFF.
2. Press ▲ TEMP or ▼ TEMP for 5 seconds. The display will flash once and change modes (°C to °F or vice versa).
3. Press the HEATER OFF button to switch the heater ON.
When either the ▲ TEMP or ▼ TEMP buttons are depressed, the digital display will indicate the temperature setting.
After five seconds, the display will return to the actual pool/spa temperature.
In addition to the digital temperature display, there are five indicator lights:
The POOL ON light indicates the pool water temperature is controlling the heater operation.
The SPA ON light indicates the spa water temperature is controlling the heater operation.
The HEATING light comes on and stays on when the heater's burner chamber is firing. This light should be on whenever
the burner is on. This light 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
(See TO TURN OFF GAS TO THE APPLIANCE on page 13), and have a qualified service technician check the system.
