Hvac controller assemblies including air flow intrusion barriers

A heating, ventilation, and/or air condition (HVAC) controller assembly configured to be mounted to a wall of a controlled space, the HVAC controller assembly comprising:

• a front cover including at least one input/output device;
• a back plate configured to be removably secured to the front cover, the back plate configured to be positioned between the front cover and the wall;
• HVAC controller circuitry configured to be electrically coupled to one or more HVAC components of an HVAC system by way of a plurality of wires extending through a hole in the wall, the HVAC controller circuitry configured to adjust one or more environmental characteristics of the controlled space,
• a plurality of wire openings, each of the plurality of wire openings configured to receive only a single wire of the plurality of wires and each of the plurality of wires configured to extend through a different one of the plurality of wire openings;
• and
• an air intrusion barrier configured to extend across the plurality of wire openings, the air intrusion barrier configured to receive the plurality of wires and to generally form a plurality of seals against the plurality of wires;
• wherein the plurality of wire openings are configured to substantially support the plurality of wires to reduce movement of the plurality of wires relative to the air intrusion barrier.
