--went to turn on heater as usual, but saw the REM mode on display--we never had a remote system. All I'm able to do is push the 3 buttons at the same time and all that does is change the REM off to REM on. I want control of the heater's functions again, like turning it ON. I've never seen this display before today. I checked all the other things, like filter, skimmer basket in spa, my DES filter is a little over the recommended pressure (by about 1 point) but I've had the heater on before like that with no problem. How did this display code come on when we've never had a remote control hooked up to our heater?--thanks for any input-----db
