Newbie here. Long story, short version. Just upgraded from a Rev. K Jandy iaqualink RS to a Rev. T.2 as necessary to install and operate (w/o integrated controller) a new Jandy VS pump (not installed yet). Piece of cake upgrade. Mark and unplug old, plug and install new. Everything fired right up and works perfectly...except the heater. I would think that the setting on the heater in this application would be set to remote. I have tried remote and spa. I am on LP so trying to heat the pool is probably not going to happen. In any event, I can only get the spa heat to run by manually powering-on and adjusting temp from the control pad on the heater itself. No remote ability. No wiring for the heater was changed or altered. Any ideas where to start? Anybody? Thanks in advance for any assistance. I'm stumped. Robert
