Connect Prestige IAQ to Peerless 63-04

OleksiiC

Reading Prestige IAQ and Peerless 63 manuals, but can't figure out the best way to connect the kit to boiler.
Boiler to EIM:
1. Just connect R to R, Y to W (yes, Peerless doesn't quite care about naming) and C to C
2. Put isolation relay to receptacle on the transformer assembly and then R to R, G to W and C to C

Thermostat power:
1. From EIM (will boiler transformer handle both EIM and thermostat?)
2. From another transformer

What is the proven of doing that?

IDK about the other items, but IIUC, the relay is to run the circulator pump if the boiler is set up for hot water heating.
