Sounds like a cool name for a band. But that's not why I'm here.

Pentair Intelliflo relay says one relay is good for 5 amp and the other is good for 16 amp.
I will put in a circupool rj60 SWCG and a Hayward 400fdn heater.
  • RJ60 manual says Cell Current (often 2.5 to 7.8 amps when generating, otherwise 0). I doubt I'll ever use it at 50% or more on my 20k pool. No idea though.
  • Gas heater manual says 120/250 VAC, 1phase, 5.5A max current, recommend circuit protection rated at 15 amps.
So, which item should go into which relay?

Also, guessing two wires in (to each relay, bringing 240 volts) and two wires out (to each device).
 
Cell current is at 28-40V. At 240V SWG amp draw will be about 2 amps.

Either device will work with either relay.

I would put RJ60 on the smaller relay and heater on the larger.

What model gas heater? Does the gas heater manual discuss a heater cool down period? Dropping the high voltage will not let the heater cool down.
