Hi @Patrick_Caezza I think my heat source is AC and not heat pump. So I
moved Orange to W2 aux and now heat air coming out. Anything else stays
the same, Yellow is at Y1. Do you think I should update wiring as you
suggested?
Thanks for your answer @MrVacca but I currently have yellow line
connected to Y1. This morning I noticed that thermostat ignited heat
mode correctly but only cool Airs coming out instead of heat.
