Abstract:
An HVAC controller such as a thermostat may include a housing having an aperture formed within the housing and a proximity sensor that is disposed within the housing proximate the aperture. The proximity sensor may include a sense die that has a first IR detector and a second IR detector, and a lens element disposed in front of the sense die. The lens element may be shifted to one side to preferentially direct incident IR energy to the first IR detector at the expense of the second IR detector. An IR energy transparent element may be disposed in front of the lens element, and may include a portion that fits into and seals the aperture formed within the housing. A controller may be configured to receive an electrical signal from the proximity sensor indicating an approach of an individual towards the thermostat, and in response, wake-up a user interface.
Abstract:
A wall mountable connector may be secured to a wall in order to provide mechanical and electrical connections to a thermostat. In some cases, the wall mountable connector and the thermostat may, in combination, be configured to permit the thermostat to attach to the wall mountable connector only when the thermostat is in a particular orientation relative to the wall mountable connector. In some cases, the wall mountable connector includes a plurality of pin terminals that are configured to accommodate a plurality of pins extending from the thermostat. The interaction between the pins and the pin terminals may provide a lock and key arrangement between the wall mountable connector and the thermostat.
Abstract:
An HVAC controller is configured to log and record performance related data related to a performance of an HVAC system over a period of time in one or more performance logs stored in a memory of the HVAC controller. In some cases, the HVAC controller may be configured to retrieve at least some of the performance related data from the performance log that corresponds to a selected period of time that may be selected by a user, and display the retrieved performance related data on a display of the HVAC controller.
Abstract:
A wall mountable connector may be used for securing a thermostat to a wall. The wall mountable connector may provide an electrical connection between a plurality of field wires of an HVAC system and corresponding terminals of a removably mounted thermostat. The wall mountable connector may include a plurality of mounting features that are configured to provide good securement of the wall mountable connector relative to the wall, and in some instances facilitate aligning at least one of the mounting feature of the wall mountable connector with a stud within the wall.
Abstract:
A wall mountable connector to provide mechanical and electrical connections for a thermostat. The wall mountable connector may include a field wire receiving cavity, with a first column of wiring terminals and a second column of wiring terminals, with each of the wiring terminals configured to receive a field wire. Each of a first column of pin terminals may be electrically coupled with each of the first column of wiring terminals and each of a second column of pin terminals may be electrically coupled with each of the second column of wiring terminals. In some cases, the first column of pin terminals may be spaced a distance of 3 to 20 millimeters from a first side edge of the housing, and the second column of pin terminals may be spaced a distance of 3 to 20 millimeters from an opposing second side edge of the housing.

Abstract:
An HVAC controller may include a first stationary housing component, a second stationary housing component is secured relative to the first stationary housing component and a rotatable ring situated therebetween. The rotatable ring may have a first side that is configured to slide along a surface of the first stationary housing component when the rotatable ring is rotated, and a second side that is configured to slide along a surface of the second stationary housing component when the rotatable ring is rotated. The first side of the rotatable ring may have an encoded surface that rotates with the rotatable ring, and a stationary encoder may face the encoded surface of the rotatable ring. The stationary encoder may be configured to provide an output signal that is indicative of rotation of the rotatable ring that is used by the HVAC controller as a user input.
Abstract:
A wall mountable connector assembly with an optional wall covering plate is disclosed. The wall mountable connector provides electrical connections to each of a plurality of field wires and is configured to provide electrical connections to a thermostat secured to the wall mountable connector. The optional wall covering plate is configured to fit over the wall mountable connector and provide a pleasing appearance.
Abstract:
A wall mountable connector for securing a thermostat to a wall is disclosed. The wall mountable connector may include built in jumper functionality. In some cases, the wall mountable connector may include a plurality of wiring terminals as well as structure enabling an installer or other person to easily electrically connect (e.g. jumper) one or more of the wiring terminals in order to accommodate different equipment installations. For example, in some cases there may be a desire to electrically connect (e.g. jumper) or disconnect certain wiring terminals that correspond to transformer input terminals, which in some equipment installations are intended to be independently powered while in others they are not.
Abstract:
An HVAC controller includes a housing having an outer housing wall, a circuit board within the housing and a flexible circuit electrically coupled to the circuit board. The flexible circuit may provide a bias force toward a non-flexed state when flexed. A temperature sensor may be electrically coupled to the flexible circuit, which is mounted in a flexed configuration within the housing such that the bias force of the flexible circuit biases the temperature sensor against the outer housing wall.
