ZUMMESH-CCO
Zūm™ Contact Closure Output
Installation Guide
Description
The Crestron ZUMMESH-CCO is a contact closure output that enables an HVAC system
®
when a room is occupied. The contact closure output attaches to a ZUMMESH-JBOX
device (e.g., ZUMMESH-JBOX-5A-LV or ZUMMESH-JBOX-20A-SW, sold separately) so
that it can be connected to an HVAC system.
The relay closes when the room is occupied and opens when the room is vacant. The
green LED lights when the relay is closed (i.e., the room is occupied) and turns off when
the relay is open (i.e., the room is vacant).
The relay rating is 1 A, 30 Vdc/24 Vac.
NOTE: The ZUMMESH-CCO activates the HVAC system when a vacancy sensor
(ZUMMESH-PIR-VACANCY-BATT) is used.
A basic single-room Zūm system consists of Zūm mesh devices, e.g., dimmers, switches,
keypads, and sensors. The Zūm mesh devices in the room communicate directly with
each other without the need for a centralized gateway or processor.
