You right! hardly any company's in Houston sell RGPE's is why I was not quite sure, but after doing a little research/studying on Rheemote last night, I saw it was the ECM 2+ motor and read all about it. Still from looking at the whole wiring diagram on the furnace and motor wiring, it gives little details on wiring the RGPE for humidity control, and don't even know if it would be wise with a UAPM series. I even went to a class on the RGPE along with a few other products not to long ago, guess I sleep through the whole 10 minutes they spent on that furnace I guess they considered the market. After a little more investigation, it says it's compatible with single or two-stage thermostat. (For optimal performance, two-stage thermostat recommended.) so my guess is, the thermostat/brain controls the blower speed in cool mode somehow, maybe by signal type commutation. It's almost unheard of to see these type setups in Houston, "two speed" anything, so the classes we get here, the instruction is vague, and this is probably why the contractor had issues on the wiring the system with the 500 series stat, so it's mfg. instruction fault as much as the contractor. It's sad the market controls the education "somewhat" as it does here, now you want to talk 14.5 seer UAPM and a standard 80% furnace? I could write you a book and wire one of those blindfolded. Investing in a RGPE with a UAPM condenser, as cheap as gas is, and what little use for heat we have in Houston/Texas, would be like buying a Kenworth to pull your canoe.
