I have an Rheem RQNJ-A036 package heatpump. It has an HW rth 2410b stat with o/b, y, r,g and w/aux with same wire color orange, yellow ect. There is a blue present which is taped and not used with the 2410b which I assume is common(will check with meter). It is wired as a heatpump with heat strips. I have an HW vision pro TH8320 I'd like to put in it's place. The 8320 has rc,r(jumpered), o/b, y,g and c on the right heatpump side and w is opposite o/b on the conventional side. on the left side heatpump terminals are y,l, e/aux,k and s1/s2 for the outside temp sensor I will install later. My thoughts were to remove the r/rc jumper and use r with the red wire orange to o/b, y and g and connecting the taped blue to the c. This leaves me w which I figure goes to the e/aux-w2 terminal, correct ? I also are unsure about some setup toggles. 170 - #7 180- unsure with package unit. 190 unsure as orange went to o/b with package unit. #220 compressor cycle rate ? #240 use 9 ? Heatpump/aux lock outs needed ? 530 smart response ? With h/c fan, no extended timers ?



Thanks for any help. GBY

Need to have the jumper from R to RC or it won't work.

W/O/B is for the orange wire, and the stat must be set to energize the RV in heat mode.

Set both the compressor and aux cycle rate to 3 or 2.

Don't have an install manual in front of me to see the parameters of the menu to tell you about 190 etc.

Thanks. White to the e/aux/w2 then ? Ok on the jumper. I thought since the old stat didn't have rc it wasn't needed. I was figuring the stat would set the reversing valve for h/c.

Yes, white to aux. New stats need that jumped on systems with a single source power supply.


Stat needs to be set for with type of RV set you have. It can't determine that by itself.

Re "Stat needs to be set for with type of RV" Is that one of the toggles in the setup menu ?

 

[beenthere]

Yes it is.

 

[Hiskid]

Yes it is.

Would the Rheem HP install docs have the answer to if h or c is energizes O ?

I found this: Rheem and ruud brands use a b that energizes the reversing valve during heating.

Rheem/Ruud are different from every other brand - the RV is energized in heat ("B" terminal or "O/B" with a toggle in the setup).
