Operation
In the POOL or SPA modes, the actual water temperature
is displayed along with the desired water temperature
(SETPOINT). When the water temperature is above the
setpoint, “Water Temp” will alternate with “No Demand.”
When the water temperature is below the setpoint and the
heater is firing, “Water Temp” will alternate with “Heating.”
To adjust the setpoint temperature, make sure the control
is in the appropriate mode (POOL or SPA) and push the
UP or DOWN buttons.
By default, the setpoint range is 50-104°F (10-40°C). See
MAX Settings on
page 25
to increase the MAX setting,
if necessary.

Service Menu and Fault History
To access the Service Menu and fault history, press the
Mode and UP buttons simultaneously for 3 to 5 seconds.
The heater will continue to operate while in the Service
Menu. The first screen displayed is the Flame Strength
indicator, which indicates the pilot flame current using a bar
graph and numerical display. A signal of less than 4 bars
indicates a weak flame signal and may require service.
Refer to the Troubleshooting section for possible causes
and corrections.

Press the DOWN button. The Run Time indicates the total
hours of operation for the pool heater, as measured by the
amount of time that the main gas valve has been powered.
The Cycle count indicates the number of on/off cycles of
the heater, as measured by the number of times the pilot
valve has been powered.

Press the DOWN button. The Fault History displays up to
ten faults in memory. The order of the faults begins with
“Fault Last,” which is the most recent fault, and proceeds
through ten most recent messages in chronological order.
The second line of the display shows the fault message.
If there are no faults in the history buffer, the second line
reads “All Faults Clear.”
