I have a Lennox heat pump system. Home is all electric and system is 2 stage heat, single stage cool. The thermostat is noting a problem code e106 for wiring issue on W2 aux. The unit senses equipment installed on the diagram below. However I don’t think the aux heat is actually working. I’ve tested the heat strips and there is no open circuit. Heat pump heat seems to work fine. Should aux heat wire be connected on W1 instead? Also note that the temp setting for “when to use heat pump compressor” only has “always” option showing. Seems like its not seeing heat strips installed?

Hi Miketyler,
Thanks for reaching out and we're sorry for the delay.
Based on the post details, you have a heat pump with a 2 stage heating. The O/B (orange) wire acts as the first stage of cooling and heating at the same time. With this, we could connect the white wire to the W1 instead for the second stage of heating.
Let me know how it goes by replying to this thread.
Best regards,
Ryan
