You can shift to 186 degree or back to 176 degrees. I am in the same situation as yourself. I have heard there is 1 other solution which I am currently implementing in our home (period 8), that is to open the area toward the west. So, since a road is in the west, I am removing trees, shrubs, etc. in that area. Also, since 3 controls 8, I have found a power strip with a glowing red light works well in the N1 bedroom.
