    RTH9580WF Heating Issue

    Hello everyone. I'm having an issue with the wiring. I have a Nordyne/gibson electrical heat pump with auxiliary. I have the white heating wire hooked up to w2 aux, and the black auxiliary wire hooked up to the same terminal (w2). For W-O/B, I have an orange wire in that terminal. Seems like I can't get the auxiliary coils to kick in although the thermostat says auxiliary on. Not sure what to do, but it's only 5F in northern Virginia and I'm freezing. Any help would be a godsend!

    Have you tried to put your system in electric heat mode by pressing system on the screen and selecting electric heat?
