The CRISTALCONTROLS low voltage decorator wall switch provides an attractive companion wall station for a low voltage sensor system. Many spaces now require by code (e.g., ASHRAE 90.1, IECC, Title 24) manual on, partial-on, or full range dimming user operation in addition to an occupancy sensor providing automatic off control. The simplest way of achieving this is by adding a low voltage wall station that interfaces with the power pack controlling the rooms lighting. Adding a switch to a low voltage sensor system also enables users to override a space’s lighting off if necessary. Functioning as a momentary switch, this one button wall station is intuitive to use and provides pleasant tactile feedback. Visually, the unit matches the CRISTALCONTROLS line of wall switch sensors, ensuring a consistent style across multiple spaces on a project. Additionally, the single button switch has an integrated locator LED with multiple color and intensity settings. Three button dimming units have an integrated 0-10V output, intuitive raise/lower buttons, and a five LED level indicator.
The CRISTALCONTROLS low voltage decorator wall station functions as a momentary switch with a pulse length of 250 msec. Typically, it is utilized along with any CRISTALCONTROLS power pack with the auxiliary switch input option (e.g. model CC-SWX-900-AX). Using a four-conductor low voltage wire (typically 18 AWG), low voltage power, common, and relay status is wired from the power pack to the switch. The switch output is then wired back to the power pack’s auxiliary switch input. For applications requiring Vacancy (e.g., Manual On) operation, the switch signals the power pack to turn on lighting after the unit’s button is pressed. To achieve multi-way switching, two or more single button units can be wired in parallel. For three button units with integrated dimming, an additional 0-10V output wire is provided to connect directly to fixtures. By default, the lights will always come on to the last dim level, however the unit can be programmed to turn-on to a preset level in order to accommodate partial-on applications.
