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 ring, “Water Temp” will alternate with “Heating.”
To adjust the setpoint temperature, make sure the control
is in the appropriate mode (POOL or SPA) and touch the
UP or DOWN keys.
By default, the setpoint range is 50-104°F (10-40°C). See
"Program Menu" on page 31 to adjust the MAX setting,
if necessary.

To access the Service Menu and fault history, press the
SERVICE key 1 time. The heater will continue to operate
while in the Service Menu.
The rst screen displayed is the Flame Strength indicator,
which indicates the ame current using a numerical display.
A signal of less than 1.0 μA indicates a weak ame signal
and may require service. Refer to "Troubleshooting" on
page 48 for possible causes and corrections.

Press the DOWN key. The "Hours" run time indicates the
total hours of operation for the pool heater, as measured by
the amount of time that the gas valve has been powered.
The "Cycles" count indicates the number of on/o cycles of
the heater, as measured by the number of times the valve
has been powered.

Press the DOWN key. The Fault History displays up to ten
faults in memory. The order of the faults begins with "Last
Err" which is the most recent fault, and proceeds through
the ten most recent messages in reverse chronological
order. Run time hours at the moment of the fault are
displayed at the end of line one. The second line of the
display shows the fault message. If there are no faults in
the history buer, the second line reads “All Faults Clear.”
