Clients usekeypads to control the lights connected to the WPM.C O N N E C T I O N T O P R O C E S S O RThe WPM is wired like a six-zone GRAFIK Eye ® controlunit (GRX-3506). Each HomeWorks processor has threeconfigurable links each capable of controlling up toeight WPM or GRAFIK Eye control units. Thisconnection requires two pair [one pair 1.0mm 2 (#18AWG), one pair 0.5-1.0mm 2(#18-22 AWG) twistedshielded] Class 2/PELV wire. Lutron ® wire model GRX-CBL-346S-500 may be used. The maximum cable lengthis 610m (2,000 feet), and this link must be wired in adaisy-chain configuration.The wattage and load type specifications of the WPMare the same as six-zone GRAFIK Eye control unit(GRX-3106/3506 models). All connections on the backof the WPM are identical to those on the six-zoneGRAFIK Eye control unit.D E F A U LT S C E N E B U T T O NEach WPM has a default scene button on the frontthat allows a user to toggle between a preset sceneand OFF. This scene is stored inside the WPM and canbe activated at any time.
