摘要:
A load control system for a building having a lighting load, a window, and a heating and cooling system comprises a lighting control device for controlling the amount of power delivered to the lighting load, a daylight control device (such as a motorized window treatment) for adjusting the amount of natural light to be admitted through a window, and a controller for adjusting a setpoint temperature of the heating and cooling system to thus control a present temperature in the building. In response to receiving a demand response command, the controller controls the lighting control device, the daylight control device, and the heating and cooling system so as to decrease a total power consumption of the load control system. The load control system may comprise a controllable switching device for disconnecting power to or disconnecting the control lines to one or more components of the heating and cooling system.

A dimmer switch for controlling the amount of power delivered to and thus the intensity of a lighting load comprises a visual display operable to provide a visual indication representative of energy savings and usage information. The dimmer switch comprises an intensity adjustment actuator, such as a slider knob or a rotary knob, which may be coupled to a potentiometer for adjusting the amount of power delivered to the lighting load. The potentiometer may comprise a dual potentiometer including a resistive element and a conductive element having a cut. The visual display may comprise a single visual indicator, which may be illuminated a first color, such as green, when the intensity of the lighting load is less than or equal to the eco-level intensity, and illuminated a second different color, such as red, when the intensity of the lighting load is greater than the eco-level intensity.
摘要:
A load control system for a building having a heating and cooling system and a window located in a space of the building uses a daylighting procedure to adjust the amount of power delivered to the lighting load in response to the amount of daylight entering the window, and controls amount of daylight entering the window in order to attempt to reduce the power consumption of the heating and cooling system if the daylighting procedure is not causing the heating and cooling system to save energy. If the lighting load is consuming more energy when the fabric of the motorized window treatment is at a position above the fully-closed position than the lighting load would consume if the fabric was at the fully-closed position, the motorized window treatment moves the fabric to the fully-closed position.

A load control system for a building having a heating and cooling system and a window located in a space of the building controls amount of daylight entering the window in order to attempt to reduce the power consumption of the heating and cooling system, and adjusts amount of daylight entering the window if the heating and cooling system is not saving energy. A motorized window treatment of the load control system is operable to move a fabric covering the window in a first direction, and a temperature control device is operable to subsequently determine if the heating and cooling system is consuming more energy than when the fabric was in the initial position. The motorized window treatment then moves the fabric in a second direction opposite the first direction if the heating and cooling system is consuming more energy than when the fabric was in the initial position.

A load control system comprises a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the load control device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The load control device receives both power and communication over two wires, and the controller generates a phase-control voltage that has at least one timing edge in each half-cycle, and transmits digital messages by modulating a timing edge of the phase-control voltage relative to a reference edge. The controller may be operable to receive inputs from a plurality of different input devices, and the load control device may be operable to control a plurality of different loads.
摘要:
A motorized window treatment to automatically control the position of a covering material in front of a window to save energy. The motorized window treatment has an eco-mode whereby to at least one climate characteristic is measured by a sensor to save energy by decreasing the load on a heating and/or cooling system of the room in which the motorized window treatment is installed. The motorized window treatment opens the covering material on sunny winter days to allow energy from sunlight to be stored in the mass of the room, and closes the covering material at night to insulate the room and allow the energy from the sunlight stored in the mass of the room to heat the room and reduce the load on the heating and cooling system at night.
