If the PRS fault code is displayed, it indicates that
there is insufficient water flow through the heater.
Make sure the pool filter and pump strainer are clean
before calling a service representative.
DIAGNOSTICS
The digital thermostat models are equipped with on-
board diagnostic controls. If there is a safety fault, a
fault code will be displayed along with a service
indication.
READING A FAULT
The word “SERVICE” will flash on and off if the PC
board detects a known fault. The fault will be dis-
played in three big letters on the lower left of the dis-

NOTE: The LCD temperature display may not agree with the temperature reading of your pool or spa ther-
mometer. The heater reads the water temperature at the inlet. 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.
