The pool heater touchpad, located on the upper front
panel of the heater, allows the user to select either
POOL or SPA operation, and to adjust the setpoint
temperature. The LCD display window indicates the
mode (OFF, SPA, POOL) and the actual water temper-
ature. A manual power switch provided below the
touchpad turns the control power ON or OFF.
Mode Button
The MODE button is used to select either POOL or
SPA operation. It also allows the user to turn the
heater off electronically, allowing the LCD display to
remain energized and to continue showing the actual
water temperature.
Temp Buttons
If the heater is in POOL or SPA mode, the desired
water temperature (SETPOINT) will also be displayed
and may be adjusted using the UP or DOWN buttons.
Operation
In the POOL or SPA modes, the actual water temper-
ature is displayed along with the desired water temper-
ature (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 con-
trol is in the appropriate mode (POOL or SPA) and
push the UP or DOWN buttons.
Service Menu and Fault History
To access the Service Menu and fault history, press
the MODE and UP arrow buttons simultaneously for 3
to 5 seconds. The heater will continue to operate nor-
mally while in the Service Menu. The first screen dis-
played is the Flame Strength indicator, which indicates
the pilot flame current using a bar graph and numeri-
cal display. A signal of less than 4 indicates a weak
flame signal and may require service. Refer to Section
5 – Troubleshooting for possible causes and correc-
tions.

by the number of times the pilot valve has been pow-
