Features

Create a stronger, wider, and more robust Zigbee mesh network than

ever before using the Zigbee IO. Eliminate any network “dead spots” by

increasing the reach and density of your Zigbee mesh. Improve Zigbee

signal latency and provide your customers with higher reliability and

responsiveness as they use the devices connected to their Zigbee mesh

network.

The Zigbee IO (Z2IO) is a single device that combines the features of:

• Remote relays (up to two)

• Remote contact sensors (up to four)

• Remote thermistors (two)

• Internal contact (internal magnetic reed switch)

• Zigbee-to-IR converters

Any of these inputs can be used to trigger and control automated

events—such as sending an e-mail or turning on a cabinet light when its

door is opened—throughout the Control4 system.

With this device, you can reduce the need to run control wires over long

distances (or where you can’t run any wires at all).

As Zigbee to IR

The two 3.5 mm IR ports allow you to connect up to two standard IR

emitters to control any IR-controlled devices, such as TVs, DVRs, and

receivers.

When connecting IR emitters, make note of which port each emitter is

connected to (labeled “1” and “2”).

IR codes sent from the controller to the Zigbee IO are cached at the

device, resulting in faster IR control response times.

Micro USB IR 1 IR 2

Note: Y IR cables can be used, or IR cables can be spliced

together (in parallel, not in series), to increase the number

of controlled devices. Be aware that these connected

emitters cannot be controlled independently but will all ﬁre

simultaneously from the shared IR port. Test to verify that

there is no crossover code functionality between devices

sharing the same IR port to avoid unwanted side eects.

As a contact and relay

The device has an internal contact along one edge that can be used to

detect open or closed states when installed with a mounted magnet. Up

to four contacts (besides the internal contact) or two additional relays,

or a combination of the two, can be used. Each option is outlined below

in “Contact and Relay Wiring Options,” and after it’s physically wired,

the correct option must be set on the Properties tab as outline further

below in the section “IO Options.”

As a relay

As a relay, this device provides wireless control of garage door

openers, window coverings, ﬁreplaces, and pumps (along with other

relay control applications) inside or outside the home. It integrates

into Control4 systems as standard relays that can be opened, closed,

toggled, or pulsed.

The relay enables wireless control of any device controllable by one

or two low-voltage SPST relays or one simulated SPDT relay. These

functions appear in a Control4 system as relay outputs (relays) in

Composer Pro.

Installation Guide

As a contact sensor

Depending on the selected IO conﬁguration, up to four external

contacts are possible. As a contact sensor, this device allows wireless

monitoring of garage doors, gates, windows, mailboxes, doorbells,

and pool or spa covers (along with other contact sensor monitoring

applications you integrate or devise). These functions appear in a

Control4 system as contact sensor inputs, which can trigger home

automation events.

The internal contact is a magnetic reed switch. To use this internal

contact, the Z2IO should be mounted so that the indention (along

the same edge as the identify button) comes in close proximity to a

mounted magnet (not included) in a fully closed state (door is closed).

When the door opens, the magnetic connection is lost, and that state

change is pushed to the system.

Contact and relay wiring options

There are ﬁve wiring options for contacts and relays. After they are

physically wired (as explained below), the correct option must be

manually selected on the Properties tab using the IO Properties drop-

down box.

Option 1: Two Relays using R1, R2—Two independent, single pole

single throw (SPST) relays. Each relay controls a single circuit.

• Relay 1 is wired to pins C1 and pin C2.

• Relay 2 is wired to pins C3 and pin C4

Option 2: Four Contacts using C1, C2, C3, C4—Four independently

sensed circuits.

• Contact 1 is wired to pin C1 and pin Cm (Common).

• Contact 2 is wired to pin C2 and pin Cm (Common).

• Contact 3 is wired to pin C3 and pin Cm (Common).

• Contact 4 is wired to pin C4 and pin Cm (Common)

Option 3: One Relay (SPST) and Two Contacts using R1 and C1, C2.

• Relay 1 is wired to pin C1 and pin C2.

• Contact 1 is wired to pin C3 and pin Cm (Common).

• Contact 2 is wired to pin C4 and pin Cm (Common).

Option 4: One Relay using R1 and R2 (SPDT)—The two relays

operate together to simulate a single SPDT (single pole double

throw) relay. However, unlike a true SPDT relay, both relays will

open during a power failure.

• Relay 1 is wired to pin C1 and pin C2.

• Relay 2 is wired to pin C3 and pin C4.

Option 5: One Relay using R1 and R2 (DPST)—The two relays

operate together to simulate a single DPST (double pole single

throw conﬁguration) relay. However, unlike a true DPST relay,

both relays will open during a power failure.

• Relay 1 is wired to pin C1 and pin C2.

• Relay 2 is wired to pin C3 and pin C4.

As a thermistor and humidistat

The device contains an integrated thermistor and humidistat, as well as

a connection for an external thermistor, allowing it to be used almost

anywhere to report environmental conditions or to inform the climate

control system. The thermistor senses temperatures from 0 to 40 °C

(32 to 104 °F), and the humidistat senses humidity from 5% to 90%. The

device checks the temperature and humidity every ﬁve seconds. If

the temperature has changed more than 0.28 °C (0.5 °F), the device

reports the new temperature. If the humidity has changed more than

0.5%, the device reports the new humidity percentage.

Data from the integrated thermistor and humidistat is always

available, regardless of the selected IO conﬁguration.

Notes:

• The humidity and internal and external temperature

outputs can be connected (bound) to the Control4

Wireless Thermostat by Aprilaire (C4-THERM).

• A value of -40° in the Remote Temperature ﬁeld could

indicate either a negative temperature or that no remote

thermistor is connected.

• The integrated humidistat will return a zero value after

the device is rebooted until the actual humidity value can

be reported.

• To display the temperature and/or humidity in Navigator,

add the “Temperature Display Driver (OS 2.10+)” to the

project and connect the driver’s temperature driver to the

Z2IO.

• Given the variations in temperature and humidity

measurements and environments, it may be necessary

to independently test and verify the local and remote

temperature and humidity. The properties Local

Temperature Oset, Remote Temperature Oset, and

Local Humidity Oset can be used for this purpose.

Installing

1 Place the device in a location which ensures the following:

• Easy access to any externally-connected wires

• Zigbee mesh networking eciency

Note: Make sure the device has good Zigbee wireless

reception by (1) ensuring it is within range of another Zigbee

device and (2) avoiding other electrical equipment that may

cause interference with the Zigbee signal (such as cordless

telephones that operate on the 2.4 GHz frequency.)

• Avoiding unnecessary exposure to extreme environmental

conditions.

IMPORTANT! Do not place the device in direct sunlight.

2 If an external thermistor is used with the device, place it away

from direct sunlight, drafts, doorways, skylights, windows, and

exterior walls for best accuracy.

3 Detach the tray from the cover by inserting a ﬂat screwdriver into

the opening slot in the side of the cover and pushing in gently,

while at the same time pulling the cover out and away from the

tray.

to the tray. The tray holds the wiring

terminals and is mounted to a wall or

ﬂat surface.

The cover “rocks” into contact with the tray.

To separate the two, insert a screwdriver or

other ﬂat object into the opening slot on the

side of the cover, gently push in and then

“rock” it away from the tray.

4 Position the tray against the wall or other ﬂat surface.

5 If you are using the internal contact, position the device so that the

narrow indentation that marks the internal contact (on the long

edge of the cover) aligns with the external magnet (not included).

6 Mark the locations of the four screw holes on the wall.

7 If mounting the device to drywall, remove the tray from the wall

and drill four 4.75 mm (3/16-inch) mounting holes at the four

screw hole locations (A) previously marked on the wall.

8 Thread any relay wires, contact wires, and external thermistor

wires from the wall through the openings in the tray and to the

terminal block.

T C1C2CmC3C4

PWR

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 cover edge’s two

latching tabs with corresponding

tab receivers on the tray’s edge.

B. Close the cover by rocking

it toward the other end of the

tray until it snaps into place with

the tray.

12 For Zigbee to IR, connect any IR emitters to the two IR ports, then

ax 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.

Conﬁguring

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

o.

Tip: Two SPST relays can optionally be linked to simulate a

single SPDT relay. However, unlike a true SPDT relay, both

relays will open during a power failure.

4 Add generic contact drivers (such as Door Contact Sensor, Gate,

and Motion Sensor) and relay drivers (such as Blinds, Door Lock,

and Pump) in System Design view, then connect the generic

driver to the appropriate connection on the C4-Z2IO device in

Connections view.

5 For programming, use these events:

• Online: Triggers when the device comes online.

• Oine: Triggers when the device goes oine.

• Reboot: Triggers when the device reboots.

Properties

General properties

• Log Level: Standard for most drivers, this property allows

you to ﬁlter which message types display in the Lua Output

window. Options 0 - 5 correspond to Fatal through Trace levels,

increasing in level of verbosity. Options are 0=Fatal, 1=Error,

2=Warning, 3=Info, 4=Debug, and 5=Trace. Default is 1 - Error.

• Log Mode: Activates logging of diagnostic information. The

log level is set in the above property. Options include O, Print

(to the window), Log (to the Director Log), and Print and Log

(both). Default is O.

• Driver Version: (Read only) Shows the version number of the

driver currently in use.

• Device Status: (Read only) Shows the current status of the

product, whether online or oine. However, in some cases, the

device may not report its status immediately, such as when the

device is rebooting.

• Firmware Version: (Read only) Shows the version number of

the ﬁrmware currently in use on the device. The ﬁrmware will

be updated automatically over the air when the Control4 OS

is updated and when that update includes a new ﬁrmware

version for this device.

• Bootloader Version: (Read only) Shows the version number of

the ﬁrmware currently in use on the device. The bootloader can

only be updated by Control4, so this property is for support/

diagnostic information only.

• LED Mode: Determines the behavior of the LED light on the

top/front of the product. Options include O, Zigbee (which

shows the Zigbee status; see “Identiﬁcation and Button Presses”

below), and IR (which shows activity when IR signals are sent

to the IR ports). Default is O. When the property is set to O,

button presses should still temporarily prompt the LED to show

the status.

Humidity properties

• Local Humidity: (Read only) Shows the relative humidity

measured where the device is located. The value is shown as a

percentage.

• Local Humidity Oset: The humidity sensor provides accuracy

of +/- 4% relative humidity. Adjusting the Local Humidity Oset

can result in increased inaccuracy of relative humidity reporting

without using humidity calibration equipment for validation.

Temperature and humidity properties

• Temperature Scale: Sets which scale is used to calculate

the temperature used in the Local and Remote Temperature

properties described below, and aects only the Properties

tab’s settings. Options include Fahrenheit and Celsius. Default

is Fahrenheit.

• Local Temperature: (Read only) Shows the most recent

reported temperature recorded by the internal thermistor. The

scale of the temperature is determined by the Temperature

Scale property.

• Local Temperature Oset—Modiﬁes the reported local

temperature to account for environmental variances. The

temperature can be changed downward or upward by a

maximum of 20 degrees. The default is 0(no correction).

• Remote Temperature: (Read only) Shows the most recent

reported temperature recorded by the remote thermistor. The

scale of the temperature is determined by the Temperature

Scale property.

• Remote Temperature Oset—Modiﬁes the reported remote

temperature (the temperature recorded by an external

thermistor) to account for environmental variances. (When

multiple temperature sensors are located in the same

room, you may notice each sensor shows a slightly dierent

reading. This results from normal manufacturing variances in

temperature sensors and the device’s position/location in the

room.) The temperature can be changed downward or upward

by a maximum of 20 degrees. The default is 0(no correction).

IO properties

• IO Options: Tells the device how its eight conﬁguration pins are

assigned. The selected option is retained even after a system

reboot or update.

• Option 3: R1 (SPST), C1, C2: One relay (single pole single

throw) and two contacts.

• Option 4: R1 (SPDT [single pole double throw]): The two

relays operate together to simulate a single SPDT (single

pole double throw) relay. However, unlike a true SPDT relay,

both relays will open during a power failure.

• Option 5: R1 (DPST [double pole single throw]): The two

relays operate together to simulate a single DPST (double

pole single throw conﬁguration) relay.

Notes:

• The IR emitter control, internal contact, internal thermistor,

and internal humidistat remain active regardless of the

selected IO conﬁguration.

• The selected IO option will change the available

connections, so existing connections will be disconnected

or deleted.

• The selected IO option determines the available ﬁelds in

Contact properties and Relay properties.

Contact properties

• Contact Internal Status: (Read only) Shows the status of the

static connection for the internal contact.

• Contact 1-4 Status: (Read only) Represents the status of the

wired contacts if IO Option 1, 3, 4, or 5 is selected.

Relay properties

• Relay 1 Power Up State and Relay 2 Power Up State: (Read

only) Represents the status of the relays if IO Option 1, 3, 4, or

5is selected. The options are Restore Last State, Set To OPEN,

and Set To CLOSED. The default is Restore Last State.

• Relay 1 Status and Relay 2 Status: (Read only) Represents the

status of the relays if IO Option 1, 3, 4, or 5is selected.

Actions tab

Buttons located on the Actions tab allow you to view version and

diagnostic information and force relay actions. (Relay actions will

always be shown, regardless of the IO conﬁguration.)

• Version Information: This action button will display the versions

of the driver’s Base Template and Template, as well as the

Boot Loader to the Lua Output window of the Lua tab. The Log

Mode property does not have to be set to Print to display this

information to the window.

• Diagnostic Information: This action button will display the

following information to the Lua Output window of the Lua

tab (the Log Mode property does not have to be set to Print to

display this information to the window): device Zigbee MAC

address, Zigbee mesh PAN id, Template Version, Base Template

Version, Boot Loader Version, Zigbee Node ID.

• Relay 1 Close and Relay 2 Close: These action buttons will

trigger the corresponding relay to close.

• Relay 1 Open and Relay 2 Open: These action buttons will

trigger the corresponding relay to open.

Troubleshooting

If the device is not working:

• Reboot the device by disconnecting power, then re-connecting

power.

• Check for proper wiring. See the “Wiring Conﬁguration” diagrams.

• Review the log in the driver’s Lua tab.

• Restore factory defaults (13 button presses).

Note: Un-identifying a device o the Zigbee mesh will cause it to do a

factory reset. A factory reset reverts all relays to the open state, and

the settings for Power Up State will revert to Restore Last State. The

settings are preserved, however, after a power cycle or reboot.

LED diagnostics

The indicated statuses appear during device identiﬁcation and when

the ID button is pressed once.
