The disclosure describes an environmental control device with a head unit including processing circuitry and one or more sensors configured to send signals to an environmental control system to make adjustments to the room environment. The head unit is configured to connect to a wall plate that supports the head unit. The wall plate may include an ID device configured to identify the type environmental control equipment to which the wall plate is configured to connect. Once connected to the wall plate the head unit may detect the ID device, determine an ID value from the ID device and customize a presentation of setup parameters for the head unit.

Identification device for an HVAC controller

In some examples, a system controls a set of heating, ventilation, and air conditioning (HVAC) components in order to regulate one or more parameters of a building. The system includes an HVAC controller device including a dial and a touch screen display. Additionally, the system includes an external server configured to communicate with the HVAC controller via a communication link. The external server is configured to receive data which indicates a set of information from one or more devices. Additionally, the external server is configured to generate, based on the set of information and a set of screen templates stored in a memory of the external server, a screen for display by the touch screen display without updating firmware of the HVAC controller device, and output, to the HVAC controller device, the screen for display by the touch screen display.

Generating screens for display by HVAC controller using templates

Systems, assemblies, and methods include features for selecting a fan speed priority setting to facilitate dehumidification of a space while maintaining a comfortable temperature in the building across a range of cooling loads. In one example, an electronic assembly may operate a multi-speed fan at a lower fan speed or higher fan speed based, at least in part, on a current cooling load on the cooling system of the building and a dehumidification high fan speed priority setting entered by a user.

Dehumidification control system

An HVAC controller may include a user interface, along with a memory for storing a recurring programmable schedule having two or more time periods. The user interface may be configured to allow manual modification by a user of the recurring schedule stored in the memory, wherein the user can associate an HVAC-off control mode with any of the two or more time periods. In the HVAC-off control mode, the HVAC controller may not cycle the HVAC unit on regardless of the temperature of the air in the inside space. The HVAC controller further may include an output that is configured to issue operational commands to the HVAC unit in accordance with the programmable schedule.

HVAC schedule with designated off periods

The occupancy status of a building space may be determined by sensing an indication of motion in the building space, in response to sensing the indication of motion in the building space, starting an occupied time period having a length during which the building space is indicated as being occupied, determining a measure related to a number of subsequent sensed indications of motion in the building space during the occupied time period, and selectively adjusting the length of the occupied time period based on the measure related to the number of subsequent sensed indications of motion in the building space during the occupied time period.

Remote sensor with improved occupancy sensing

An HVAC controller receives signals from a plurality of sensors positioned in different spaces. The HVAC controller includes a housing and a user interface that is accessible from an exterior of the housing. A controller is configured to control the HVAC system using a control temperature that comprises a weighted combination of two or more of the current temperatures reported by the plurality of sensors. The controller tracks which of the different spaces are currently occupied and how long each of the currently occupied spaces have been occupied, and as a currently occupied space remains occupied for a longer period of time, the controller provides increasing weight over time to the current temperature reported by the sensor of the plurality of sensors that is in that currently occupied space, and controls the HVAC system in order to drive the control temperature towards a temperature set point.

Temperature sensing strategy with multiple temperature sensors

An HVAC controller that monitors a current performance level of an HVAC system, and determines if the current performance level falls below a minimum performance threshold level for at least a first predetermined amount of time. The HVAC controller may be configured it display an alert on the display of the HVAC controller if the HVAC controller determines that the current performance level has fallen below the minimum performance threshold level for at least the first period of time. In some cases, the HVAC controller may remove the alert from the display of the HVAC controller if the current performance level subsequently rises and remains above the minimum performance threshold level for at least a second predetermined amount of time. In some cases, the first predetermined amount of time may include a utility shutoff period component and/or a defrost cycle period component.

HVAC controller with HVAC system failure detection

An HVAC controller for controlling an HVAC system may be configured to enroll one or more wireless devices, and once one or more wireless devices are enrolled, to prompt the user to enter an identifier, a location, a device type and/or a function for one or more of the enrolled wireless devices. The HVAC controller may use the identifier, location and/or device type to identify each of the enrolled devices. This may facilitate a user in selecting various sensors to participate in sensor averaging, identifying where certain sensor data is originating, identifying devices having a low battery condition, as well as performing other tasks as desired.

Method and system for configuring wireless sensors in an HVAC system

An HVAC system includes an HVAC unit having a cooling mode and a heating mode for conditioning the air in an inside space, and a programmable thermostat located remotely from the HVAC unit. The HVAC unit may have an onboard controller configured to control when the HVAC unit is in the cooling mode or heating mode, and whether the HVAC unit is activated or not. In some cases, the onboard controller of the HVAC unit may use a common temperature setpoint when controlling in the cooling mode and the heating mode. The programmable thermostat may have a programmable schedule with a plurality of time periods, where each time period has a heating setpoint and a cooling setpoint separated by a dead band. The onboard controller of the HVAC unit may be configured to accept input signals from the remotely located thermostat. The remotely located thermostat may send one or more input signals to the onboard controller of the HVAC unit in accordance with the programmable schedule, where the one or more input signals cause the onboard controller of the HVAC unit to set the HVAC unit to a particular one of the cooling mode and the heating mode, and to activate the HVAC unit so as to condition the air in the inside space in the particular one of the cooling mode and the heating mode.

Remote control of an HVAC system that uses a common temperature setpoint for both heat and cool modes

A processor and power broker for controlling the obtaining, distribution and usage of electrical power for electronic devices such as peripherals of thermostats. Sources of power may incorporate batteries, energy harvesting modules, energy storage capacitors, and power lines. The power broker may maintain charge on the capacitors, operate the energy harvesting modules, control usage of the batteries, and utilize power line sources when available. Loads such as the peripherals may need to request approval for energy usage. Energy usage and conservation may be managed by the power broker according to a power scheme. A power scheme may consist of a set of rules as to how energy usage by the peripherals is to be managed. The rules may also indicate as to how the energy sources are managed.

Power broker module

An HVAC remote controller for use in an HVAC system is described. In some instances, the HVAC remote controller may include a wirelessly interface for communicating with one or more HVAC controllers and/or other HVAC devices. The HVAC remote controller may be configured to execute a user setup routine for entering user setup information, where the user setup routine may cause the HVAC remote controller to display a sequence of two or more user setup screens, sometimes at a common menu level rather than a sub-menu. Some or all of the two or more user setup screens may include, for example, a message center indicating a parameter or function to be set, one or more buttons for adjusting or selecting the parameter or function, and a next button to advance the user setup routine to a next screen in the sequence of user setup screens.

User setup for an HVAC remote control unit

Methods of providing dehumidification control in unoccupied spaces are disclosed. An illustrative method can include the steps of providing a controller having an away mode of operation adapted to provide dehumidification within the interior space of a building or room, providing one or more system components adapted to control the humidity and/or temperature within the interior space, initiating the away mode of operation within the controller, and operating the one or more system components for at least one cycle to reduce the humidity within the interior space.
