The C150 module provides the main processor and communication for the C150-155 six zone control and integrated iZone control.

To see an example of where the C150 is connected into to a typical system click here

Zone ports

Connect the RJ12 cables from the damper motors here. Start at zone 1 and connect sequential ports. ie 1,2,3,4.......etc

Transformer connection

Connect the iZone transformer here. Part number CT24ACM

C225 / CEPC pairing button

The pair button can be used to pair wireless CEPC controllers  as well as wireless sensors CRFS and iZone WiFi bridges (COCB)

AC unit module connector

When used for integrated AC / Zone control an AC module is connected to the C150. This module is a C325. Each different brand of AC unit has its own unique C325 module. To view assembled product please click on this link.
