Notice to owner- Thermostat operation

Your heater is equipped with a microprocessor- controlled thermostat that controls the pool or spa temperature by measuring the etmperature of water coming back through the heater. It will then monitor the temperature and turn the heater back on when it senses that the temperature is falling below set point. Small fluctuations in the return temperature are experienced during the operation of the heater. The thermostat is calibrated with a very close tolerance to insure accuracy of the set temperature. Thus, slight fluctuations may cause your heater to cycle on and off frequently. This phenomenon is not a problem. It will not harm the heater nor interfere with its function to precisely control the temperature of the pool or spa.

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 point are factory selected at 104°F for spa and 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 features an LCD display that provides status and service informa- tion. During normal operation, the heater can be in the POOL, SPA, or OFF modes.

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

NOTE: The digital temperature display may not coincide withthetemperaturereadingofyourpoolorspathermom- eter. The RP2100 reads the water temperature at the inlet of the heater. Due to the circulation characteristics of any pool or spa, the water temperature at the inlet to the heater may differ from that observed at a given location in the pool or spa.

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 set- ting, 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 representative.

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.
