This is probably a really obvious answer for those in the know, but for me, I'm still in the initial conceptual brain fog of hooking up all my equipment on a new build. I have a Pentair Intellicenter (upgrade to an Easytouch 8) and a Pentair Mastertemp 400 gas heater. I've run 120 volts to the heater and low voltage to the RS485 hookup and back to the Intellicenter. Does the Intellicenter handle all the switching of power to the Mastertemp (in which case I DON'T use a relay, just wire direct to the breaker) or do I need to use one of my relays to switch it in some way?

Thanks for your help!
 
Wire the 120 volts directly to the heater, not through a relay.

Make sure you have the 120V voltage selection plug installed in the heater

The RS-485 control from the IntelliCenter tells the heater when to run. The heater needs power on to respond to the RS-485 commands.
