Just had our pool company convert our manually-controlled pool over to a new Jandy iq904-ps automation system. The system is functional except for heater control. The heater is a newer (last 5 years) LT model. The problem is that turning the Pool Heat or Spa Heat on at the RS Panel doesn't actually activate the heater. With Pool Heat and Spa Heat off at the RS Panel, if we try controlling the heater manually (like we used to) from the heater's own controls, it will indicate a Flow Rate problem (even though the pump is running, the valves are aligned properly and water is flowing through the heater like it should). For grins, I tried activating the heat function from the RS panel while the heater was manually turned on and the Flow Rate problem indicator turned off and the heater actually started heating. So apparently heat has to be enabled on the heater and the RS panel for heat to actually heat.
Is this expected operation with this specific heater? I've read that LTs may not support "remote control" is this the problem? Is there a way around it?
