Method and system for detecting an operational mode of a building control component
First Claim
1. An apparatus comprising:
- a remote control unit;
a building component;
wherein the building component is configured to receive wireless control commands from the remote control unit but the building component is incapable of transmitting its operational status in response to a received wireless control command from the remote control unit;
a sensing module comprising;
a sensor for outputting a signal related to a measure of power drawn by the building component;
a signal conditioning circuit coupled to the sensor, the signal conditioning circuit for conditioning the signal received from the sensor;
a comparator coupled to the signal conditioning circuit, the comparator for comparing the conditioned signal to a specified threshold associated with an ON condition of the building component;
a wireless interface configured to wirelessly transmit a determination of whether the building component is ON or OFF based on a result determined by the comparator; and
wherein the remote control unit is configured to receive from the wireless interface of the sensing unit the determination of whether the building component is ON or OFF, and to use the determination to confirm whether or not the building component received a wireless control command transmitted to the building component by the remote control unit.

Abstract
This disclosure relates to methods, systems, and devices for detecting an operational mode of a building component of an environmental control system. In some instances, the apparatus may include a sensor for outputting a signal related to a measure of power drawn by the building component. The sensor may be a current sensor associated with a power cord of an air conditioning unit. The signal output by the sensor may be received by a signal conditioning circuit for conditioning the signal received from the sensor such as, for example, by amplifying and/or filtering. A comparator may be configured to compare the conditioned signal to a specified threshold associated with an ON condition and/or an OFF condition of the building component. The apparatus may include a wireless interface configured to wirelessly transmit a determination of whether the building component is ON or OFF based on the result determined by the comparator.

11. A building control system for controlling one or more building components located within a building including at least one discrete air conditioner unit, the building control system comprising:
-
a discrete air conditioner unit coupled to a power source; a discrete air conditioner controller configured to communicate with and control the discrete air conditioner unit via one or more commands transmitted to the discrete air conditioner unit via a first wireless communications path, the discrete air conditioner controller comprising a memory and a controller located within a housing, the memory storing an operating schedule for operating the discrete air conditioner unit and the controller configured to send out one or more commands to the discrete air conditioner unit in accordance with the operating schedule stored in the memory; a central coordinator comprising a user interface, a memory, and a controller, the controller of the central coordinator configured to receive and accept an operating schedule from a user via the user interface and to send at least a portion of the operating schedule to the discrete air conditioner controller via a second wireless communications path, wherein at least a portion of the operating schedule is stored in the memory of the discrete air conditioner controller; and an operational mode sensor associated with the air conditioner, the operational mode sensor comprising; a current sensor for outputting a signal related to a measure of power drawn by the discrete air conditioner unit; a signal conditioning circuit coupled to the current sensor, the signal conditioning circuit for conditioning the signal received from the current sensor; a comparator coupled to the signal conditioning circuit, the comparator for comparing the conditioned signal to a specified threshold associated with an ON condition of the discrete air conditioner unit; and a wireless interface configured to communicate a determination of whether the discrete air conditioner unit is ON or OFF based on a result determined by the comparator; and wherein the discrete air conditioner controller confirms whether the discrete air conditioner unit received the commands from the discrete air conditioner controller based at least in part on the determination of whether the discrete air conditioner unit is ON or OFF. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of confirming that one or more commands that were wirelessly sent to a building component of a building were received and implemented, wherein the building component is configured to receive the one or more commands from a remote control unit but is incapable of transmitting confirmation that the one or more commands were received and implemented in response receiving the one or more commands from the remote control unit, the method comprising:
-
wirelessly sending the one or more commands to the building component of the building, the one or more commands configured to change an operational mode of the building component to a predetermined operational mode; sensing a measure of power consumed by the building component; comparing the measure of power consumed by the building component to a specified threshold associated with the predetermined operational mode of the building component, and based on the comparison, determining whether the building component is in the predetermined operational mode; wirelessly sending one or more messages that indicate whether the building component is in the predetermined operational mode; and confirming that the one or more commands were received and implemented by the building component with the building component in the predetermined operational mode, and using the confirmation in subsequently controlling the building component. - View Dependent Claims (18, 19, 20)
