Newbie here - brand new pool ... Jandy system with the AquaLink RS One Touch Control System. Have just turned on the heater for the first time .... trying to utilize the 'Maintain Temp Settings' but it will not enable. I have configured the 'Set Temp' for both the pool and spa and have the filter and heater running. When i try to set the 'Maintain Temp Setting' it immediately reverts to 'Off'. Any ideas on what i might be missing?
