Yes, there is a return air vent.
No, there is no gap under the door into the room.
and no, there is no air leaks in Windows. Windows are pretty new.
And yes, there are plenty of insulation in the attic.
What are some clever ways that I can warm up my room a little more? The furnace does work and I do get hot air from the vents but it seems that my room just a bit too big that it's about 3 to 5 degrees lower from the thermostat.
I've looked at the Zooz's instruction and I cannot find any of their options that match my current wiring diagram. At the 3 gang receptacle, #3 switch is what also controls the light. At the 1 gang receptacle box is where I want to replace it with the Zooz's switch.
TW=traveler wire (I think)...
