I have a Raypak P-R 406A-EP-C pool/spa heater running propane; it's about 15 years old. It has a 013464F controller board that replaced the original when the latter failed in 2015.
That controller board now behaving very oddly. In SPA (local) mode, it seems to run fine. In REMOTE mode it only heats until it reaches the SPA temperature setting, disregarding what the remote says to do. The SPA max temp is set to 104F, the default. By default the SPA mode set temp. is 65F and despite the signals from the remote computer it won't try to heat; if set to 80F for SPA mode it does heat in REMOTE mode, but only to 80F, ignoring the remote call for heat.
I have reset the board to Factory Settings several times and reseated the connections. The power supply is at 26.9VDC and the flame strength is 8 Good. Has anyone else seen this failure and found a fix other than replacing the board again?
