Aqua Products RP2100 - Manual (Page 25)

To adjust the desired pool or spa temperature
setting, make sure the control is in the appropriate mode
(POOL or SPA) and push the UP or DOWN buttons to
get the desired set point temperature.
If there is a safety fault, a fault code will be displayed
along with a service indication. If the PRS fault code is
displayed, it indicates that there is insufficient flow
through the heater. Make sure the pool filter and pump
strainer are clean before calling a service representa-
tive.
Remote control operation is possible by connection
to the remote terminals on the control board. (P7) When
the remote control is operating the heater, the display will
alternatively indicate REM and the actual water tempera-
ture.

ELECTRONIC CONTROLS
The pool heater thermostat on the upper front panel
of the heater controls the pool/spa water temperature.
This control center contains a mode button, up and
down temperature adjustment buttons, and a LCD
display. The MODE button functions as a means to turn
the heater off or on in either the pool or spa temperature
setting. The LCD display indicates the mode the heater
is in and the actual water temperature. If the mode is in
POOL or SPA, the desired pool or spa temperature will
also be displayed and may be changed using the UP or
DOWN buttons. A manual switch is also provided on the
right side heater cabinet to allow the heater to be turned
off. If there is a problem in operating the heater, the fault
will be displayed and a service indicator will flash.
The electronic thermostat cannot be set above
selected maximum set points. The maximum set points
are factory selected at 104°F for spa and 90°F for pool.
These can be changed to a higher or lower value to suit
your needs, but can never be set above 107°F. In order
to change the maximum set point, push the MODE
button to the OFF mode. Open the front panel as shown
in the previous section. Find the SETMAX button on the
back of the circuit board. Push the SETMAX button until
the display indicates SET. Either POOL or SPA will be
displayed with the upper temperature limit. If the
desired mode is not being displayed, press the MODE
button to switch to the desired mode. Using the UP or
DOWN arrow buttons, adjust the upper temperature to
the desired maximum setting. If a button is not pushed
for 5 seconds, the control will return to the OFF mode.

TEMPERATURE DISPLAY-Fahrenheit vs. Centigrade
The RP2100 digital heaters will display metric (Cen-
tigrade) units. The factory default setting is Farenheit. If
you open up the front panel so you are looking at the front
of the digital board, you will find two small round buttons,
labled S1 and S2. S1 is labeled "C of F". Hold down the
S1 button for several seconds, until the board displays
"CCC", this will set the board to display in Centigrade.
Repeating the process will return the board to "FFF"
which is Fahrenheit.
