The Crestron® GLS-LCCT SolarSync™ photosensor measures the
correlated color temperature (CCT) and illuminance (lux) of outdoor,
natural sunlight. Measurements from the sensor are relayed to the
Crestron control system, which adjusts indoor lighting to match
outdoor lighting conditions.

Installation
The GLS-LCCT is designed to be mounted outdoors (on a roof)
or indoors (beneath a skylight). When determining the mounting
location, provide the GLS-LCCT with an unobstructed view of the
sky. Use a 1/2 in. knockout (0.885 in. (22.5 mm) actual hole size) when
mounting.
WARNING:
To avoid personal injury and equipment damage, consider
the following when mounting the GLS-LCCT outdoors:
•
Secure the GLS-LCCT to an IP67 or better J-box to ensure that
the enclosure remains waterproof.
•
Use a CSP-LSP Lighting Strike Protector to prevent personal
injury or damage to the control system and other devices on the
Cresnet® network from a lighting strike.
•
Mount the CSP-LSP inside the building at the point where the
Cresnet network cable enters the building. The CSP-LSP must
be properly grounded.
•
For installation, wiring, and operation of the CSP-LSP,
refer to the CSP-LSP Installation and Operation Guide at
.
Install the GLS-LCCT:
1.
Disconnect power to the system.
2.
Seat the O-ring in the groove on the bottom of the sensor.
3.
Thread the wire pigtail and the threaded nipple through the
knockout. Ensure that the sensor sits flush with the J-box.
4.
Secure the sensor to the J-box using a 1/2 in.-14 NPT locknut.
Tighten the locknut to ensure a proper seal with the J-box.
