#1 Q:   Does the AS2 really require 4 depth into the wall or can you use standard stud depth of 3.5?

#2 Q:   Can I use the thermostat for cooling the receiving room purpose? IN the manual, it states for heating purpose, buy doesnt state ONLY.
A:   The SWT is a heating only thermostat. It does not have a cooling model selection.

#3 Q:   Is there a different option for the intake vent cover so that it is flush or at least flater to wall than one appears to be that is standard?
A:   Unfortunately no. The unit mounting frame sits on top of the drywall so the grille has to cover it and any attachment screws.

#4 Q:   How is the fan speed changed on the AS2? Does the wireless thermostat adjust fan speed on the AS2?
A:   The thermostat will only turn it on and vary the speed one installs a capacitor of varying microfarads when wiring the unit.
