SensorWorx SWX-250 SERIES Low Voltage photocell and daylight harvesting
Units with the daylight harvesting (dimming) option track a spaceÕs overall illumination and dim connected lighting to achieve energy savings. During times of high daylight contribution to a space, controlled artificial lighting will be gradually dimmed to a minimum dimmed level. During times of no or low daylight contribution, controlled artificial lighting will increase back up to its maximum level. The sensor can also be configured to signal a connected power pack to switch lighting off completely in maintained high daylight conditions. Additional configurable parameters include high & low trim levels and fade rates. All photocells provide the option of selecting the ambient light threshold (e.g., setpoint) from a range of preset values or running an auto-selection mode where the unit will determine the setpoint based on the measured amount of light it is controlling. There are two types of photocell operation; ON/OFF PHOTOCELL CONTROL and DAYLIGHT HARVESTING CONTROL (see descriptions below). A photocell sensor can be used by itself (e.g.,ÊSTANDALONE operation) or together with low voltage occupancy sensors. Only one photocell sensor should be configured to control any particular group of lights. Daylight Harvesting to Low Trim Daylight Harvesting to Off Photocell Override (On/ Off) Sensors can be used to meet
