Abstract: A building controller is configured to designate one or more stored parameters as local or global. Parameters that are designated as global may be selectively communicated to remote devices and, parameters that are designated as local, may remain local to the building controller. In some instances, the remote devices may be selectable by a user, include all the other devices on the network, and/or include devices that share a common wireless accessory (e.g. an outdoor temperature sensor).

Abstract: A building controller configured to display a service reminder that reminds a user to service one or more HVAC components of an HVAC system. In some cases, the building controller includes a control module configured to determine when to display the service reminder based, at least in part, on a geographical region of the building controller and seasonal data for the geographical region. The control module may display the service reminder before an HVAC component of the HVAC system is expected to switch from being dormant during a first part of the year to being active during a second part of the year.

Abstract: Remote control of energy consumption is realized using a readily installable, flexible approach. According to an example embodiment of the present invention, a remote source communicates with a wireless controller for executing energy usage control. The remote source sends signals to the wireless controller via a gateway located near or, in one implementation, forming part of the wireless controller. In response to the signals, the wireless controller sets control settings for operating one or more of a variety of equipment types, such as a furnace, air conditioner, water heater or heat pump. With this approach, wired connections from the gateway to energy-consuming equipment do not necessarily need to be made in order to effect remote energy-consumption control. For instance, when used in connection with a controller wired to the energy-consuming equipment, the gateway need only communicate wirelessly with the controller and does not necessarily need to be coupled to the energy-consuming equipment.

Abstract: Systems and methods for the auxiliary stage control of multistage thermostats are disclosed. An illustrative multistage thermostat for a multistaged HVAC system installed within a building or structure can include a processor having a control algorithm adapted to operate the thermostat in either a normal mode for achieving rapid temperature changes within the building or structure or an economy mode for conserving energy usage. In the economy mode of operation, the thermostat can be configured to determine a target time for achieving a temperature setpoint by either delaying or suppressing activation of the system's auxiliary stage. The target time can be adjusted in part based on the past usage characteristics of the auxiliary stage, the behavior of the user, and/or the progress of the primary stage in achieving the setpoint change without operating the auxiliary stage.

Abstract: A thermostat system having dedicated informational regions in a display and associated buttons or softkeys for sequential operation. The system may maximize utilization of a sectioned display and buttons for system navigation. The informational, selection and/or action design takes into consideration operational button groupings for straightforward comfort settings as well as editing of the clock, day-of-week, schedules, and so forth. Sections, regions or areas of the display may indicate immediate button operations. The changeable information in the regions associated with the softkeys or buttons may provide sequential operation of the thermostat system. The system may have multiple schedules and setpoints for heating and cooling comfort setting flexibility. A combining of individual schedules may be automatically selected. Also, there may be a system switch mode, for example, between heat and cool, where the schedules may be individually edited.

Abstract: HVAC controllers can include at least some written instructions on, in or near the HVAC controller. In some instances, an HVAC controller can include a wall plate, a controller module that is releasably securable to the wall plate, and an instruction card slot that is disposed between the wall plate and the controller module. In some instances, a removable, slide-out instruction card may be disposed within the instruction card slot.
