I have a 10 year old lx-100 control system that needs upgrading. I believe the 521247 kit is the correct one for my system. Wanted to know if it can control both a solar heater and a pentair Propane gas heater. Will it control two areas of water a spa and the pool. Also what wireless remotes are available for this system. I would like to control the spa/pool heating and switching between the two. Thanks in advance for your help
