We have an indoor 27K gal pool and 6 person spa. The Jandy AquaLing RS 2/6 control panel inside allows us to set time and temperature and all other features for the pool and the spa. Our heater is a Max Therm 200 which heats both. The pool settings are working fine. The pool pump turns on 5 minutes before the heater, and off 5 minutes after the heater. The spa pump timer is set the same way, but the pump turns off before it is supposed to so the water is not circulating through the heater properly. Even if I turn the pump on manually, it will turn off after a while. I'm thinking it has to be a wiring issue, but our pool service cannot find the problem. Also, the heater has always displayed the temperature of the pool or spa when it is supposed to be on, even if it is not actively heating. Lately, when the spa has reached maximum temp, the display turns off even if the heater will be turning back on later. Problems seem to be related just to the spa.
