NOTE: The digital temperature display may not coincide with the temperature reading of your pool or spa thermometer. 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.

DIAGNOSTICS

The RP2100 Digital heater is equipped with on board diagnostic controls. 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.
