The outdoor HVAC unit 12A may be an air conditioner or a heat pump to name a couple of non-limiting examples. The indoor HVAC unit 12B may be a furnace, air handler, or boiler, to name a few non-limiting examples. The system controller 12C may be a thermostat to name one non-limiting example. The outdoor HVAC unit 12, indoor HVAC unit 12B, and system controller 12C work in concert to condition the interior space 16. It will be appreciated that the HVAC unit 12 may be any appliance used to condition an interior space 16, such as a geothermal heat pump, chiller, packaged unit, humidifier, and dehumidifier to name a few non-limiting examples.

The HVAC unit 12C further includes a unit controller 20 operably coupled to the unit communication device 18. The unit controller 20 is configured to control operation of the HVAC unit 12A-C, based on the environmental data. It will be appreciated that the unit communication device 18 may be a separate module or integrated into the controller 20. It will be further appreciated that any or all of the outdoor HVAC unit 12A, indoor HVAC unit 12B, and system controller 12C may contain a unit communication device 18 and controller 20.
As shown in
Each detachable faceplate 14A/B further includes an environmental sensing device 34 operably disposed within the casing 22. In the embodiment shown, the environmental sensing device 34 is disposed on the interior surface 24 of the casing 22, and is configured to acquire data within the interior space 16 in which it is placed. In an embodiment, the data include environmental data. In an embodiment, the environmental sensing device 34 includes at least one of a temperature sensing device configured to acquire ambient temperature data, a humidity sensing device configured to acquire relative humidity data, a proximity sensing device, a motion sensing device, a sound sensing device, and a light sensing device. For example, the environmental sensing device 34 may be configured to measure the ambient temperature surrounding the respective detachable faceplate 14A/B. It will be appreciated that the proximity sensing device, motion sensing device, and light sensing device may be configured to detect the presence of a person within the vicinity of the detachable faceplate 14. In other embodiments, other types of environmental sensing devices 34 may be used.
Each detachable faceplate 14A further includes a faceplate communication device 36 disposed within the casing 22, and operably coupled to the environmental sensing device 34. The faceplate communication device 36 is configured to transmit the data acquired by the environmental sensing device 34. In an embodiment, the faceplate communication device 36 is in wireless communication with unit communication device 18 to transmit and/or receive the environmental data therebetween. For example, the communication device 36 may transmit and/or receive the environmental data from to a unit communication device 18 within a thermostat, HVAC component, security panel, or home automation panel to name a few non-limiting examples. In some embodiments, the environmental sensing device 34 and the faceplate communication device may be one integral device.

In operation, each detachable faceplate 14A-B may be attached to any wall mounted electrical switching device (e.g., room light switch) using the mounting devices (e.g., screws) for the existing faceplate. The environmental sensing device 34, disposed therein, measures the ambient air temperature and/or relative humidity of the ambient air within the interior space 16 in which it is placed in one embodiment. The measured ambient air temperature and/or relative humidity is transmitted from the detachable faceplate 14A-B to the unit communication device 18, wherein the controller 20 will operate in the appropriate conditioning mode based on the measured ambient air temperature and/or relative humidity. For example, if the measured ambient air temperature is greater than the desired temperature where the detachable faceplate 14A-B is placed, the controller 20 may operate the HVAC units 12A-C in a cooling mode. In another embodiment, the environmental sensing device 34 detects whether the room in which the detachable faceplate 14A-B is located is occupied. The controller 20 may operate the HVAC units 12A-C in different modes depending on whether the room is occupied or not.
