thermistor wires from the wall through the openings in the
tray and to the terminal block.

Note: The two Cm (common/ground) pins are
connected and can be used interchangeably.
9 Insert and tighten the mounting screws.
Note: You may optionally choose to use robust two-
sided tape to mount the tray assembly to the wall or
other flat surface, as long as the tape won't prevent the
back of the tray from sitting flush against the mounting
surface.
10 Connect the wires from the tray to the terminals in the cover,
matching the proper wires to the target terminal locations.
The pin/terminal definitions are defined within Composer
Pro. See "Configuring" on the next page. (Pins Cm and PWR
are used for optional external power connections.)
Important! When using multiple external contact
sensors, or when using an external contact sensor
along with an external thermistor, you MUST connect
each device to one of the Cm pins in addition to
the appropriate sensor or thermistor pin to make a
proper wiring connection. See the "Sample wiring
configurations" section of this document for examples.
11 Attach the cover assembly to the tray:
a Align the side of the cover with the side of the tray,
engaging the plastic tabs with the corresponding holes.
b Rock the cover into place, snapping it to the tray.
c Press firmly on the bottom center edge of the cover to
snap and lock it to the tray assembly.

12 For ZigBee to IR, connect any IR emitters to the two IR
ports, then affix the emitter head to the IR window on the
device to control (such as a TV).

Connecting alternate DC power

Although a power adapter is included, you may elect to instead
connect an alternate 5-24V DC or AC power source to pins Cm-
PWR. Connect DC positive polarity to pin PWR, and negative to
pin Cm.

Connections

Static connections

Some connections in the driver are static in that they are
always available regardless of any settings/options. These
include the two IR connections, IR Output 1 and IR Output 2,
and the internal contact.

Dynamic connections

Other connections in the driver are dynamic in that the
connections will appear based on certain options—in
particular, the IO Options property. If you change to another
IO option, any connections created in the original IO option
will be broken.
To configure your device:
1 Add the device to your Composer Pro project. When
prompted to identify the device, press the ID button on the
face of the cover four times. The green LED blinks twice to
confirm the ID has been sent to the Control4 system.
- OR -
In Composer Express, add a device into the project, scan for
ZigBee devices, then press the ID button on the face of the
cover four times.
2 In the driver's Properties tab, view or configure the settings
explained below under "Properties," then click Set to the
right of the setting after each change.
3 Configure each relay's power up state. This is the state you
want the relay to adopt after a device reboot. For example,
after a power outage (resulting in a device reboot), you
may want the garage door to default to closed, the window
coverings to be restored to their last known state, and the
fireplace to be turned off.
