Abstract: A heating, ventilation, and/or air condition (HVAC) controller assembly to reduce undesired air currents includes a front cover, a back plate configured to be removably secured to the front cover, HVAC controller circuitry, a plurality of wire openings, and an air intrusion barrier configured to extend across the wire openings. The HVAC controller circuitry is configured to be electrically coupled to a plurality of wires extending through a hole in the wall to adjust an environmental characteristic of in a controlled space. Each wire opening is configured to receive only a single wire and each wire is configured to extend through a different one of the wire openings. The air intrusion barrier is configured to receive the wires to generally form a plurality of seals against the wires. The wire openings are configured to substantially support the wires to reduce movement of the wires relative to the air intrusion barrier.

Abstract: An adapter device and/or a thermostat device for use during installation and testing of in-floor heating systems. The adapter device allows for temporary electrical interconnection between a mat and an AC power source, and includes at least one switch configured to actuate based on a user-supplied force (e.g., a finger press) to temporarily electrically couple the mat to an AC power source. The at least one switch is further configured to automatically de-actuate in the absence of the user-supplied force to electrically decouple the mat from the AC power source. The thermostat device includes at least one integrated power measurement circuit for testing and diagnostics of an in-floor heating system.
