Hardware and installation

Metasys equipment controllers and expansion modules

are encased in a durable plastic housing. The plastic

housing may eliminate the need for a separate enclosure

for plenum-rated construction. Check specific controller

documentation and regional, national, and local code

requirements for appropriate applications.

Metasys CG, CV family devices feature bright, color-coded

LEDs, visible on the controller cover, that indicate the

supply power, communications bus, and EOL switch

status, as well as a variety of fault conditions to aid

troubleshooting the controller and bus.

The equipment controllers ship with a default state that

can assist in validating the wiring of the input and output

terminals prior to download of an application file. When

the controller is powered on in this state, the Fault LED

will flash in a pattern of two quick blinks and then a long

pause.
