Customer Question
Bought a new Honeywall RTH3100C...
Bought a new Honeywall RTH3100C thermostat to replace the similarly styled one manual non-programable I had. Probably model T8411R.

Old wiring G C R Y(with copper bar to W1 but no wire on it, then had one white wire looped around both W2 and E B, nothing wired to L and O.

Cool On flashes but nothing comes on after the 5 minute reset interval.

On the new thermostat I have G C R and B transferred straight. Then I ran the white wire to auxillary and jumped to E ( unfortunately with a multi-strand aluminum wire out of a $1.97 circuit tester since it is way after midnight and it was all I could find). Do I need to run another wire from aux to Y??? TIA

Mark Henley :

Hi, if you had no O terminal wire on the old one you probbaly do not have a heatpump and this thermostat is for heatpumps only, let me know, Thanks Mark

Customer:

What is RHEEM/RUUD Model RQKJ-A036JK 000 called? It has heat and air unit?

Customer:

What thermostat should I get? And how should the looped white wire be wired?

Customer:

I want a simple non-programable Honeywell like before.

Customer:

Guess I'll accept your answer and pay. Have to get working on this getting hot.

Customer:

Changed mind am running to Home Depot to buy another thermostat but will leave chat open in case you come back.
