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.

The RP2100 Spa/Pool Digital Control Panel fea- tures an LCD display that provides status and service information. During normal operation, the heater can be in the POOL, SPA, or OFF modes.

In the OFF mode, the actual water temperature is displayed.

In the POOL or SPA modes, the actual water temperature is displayed along with the desired pool or spa temperature. If the heater is firing, a flame icon will be visible.

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.

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.
