The heater operator controls are as follows:
POOL ON
Press this button to control the heater operation by the pool temperature setting.
SPA ON
Press this button to control the heater operation by the spa temperature setting.
HEATER OFF
Press this button to switch off the heater.
▲
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.
