Operating Instructions

ZXT-120

Introduction

The ZXT-120 is a Z-Wave to air-conditioner (AC) IR Extender (Figure

1) and it works with any Z-Wave compliant gateway or portable
controller by translating Z-Wave’s Thermostat commands to AC IR
control code. User can set the IR code from the built-in code library of
ZXT-120 through the configuration commands, or use the learning
function of ZXT-120 through the UI on gateway. ZXT-120 also built­in a temperature sensor that allow to report your room temperature to
home gateway. It can be utilized to control or monitor your room
temperature by your smart phone or PC while you are at office, home
anywhere or around the world.

Figure 1 ZXT-120

ZXT-120 can be configured as either “Frequently Listening Routing
Slaves” (FLiRS) or “Always Listening” node after exclusion process.

FLiRS node type is targeted for battery operated applications and it

will enter sleep mode frequently in order to conserve battery
consumption that can provide the flexibility if there is out of 5Vdc
power source. Also, user can place the unit in anywhere at home.

Always Listening node type is targeted for the needs of required a fast
response application. The installed location should come with 5Vdc
power source. Always Listening node can act as a repeater, which will
re-transmit the RF signal to ensure that the signal is received by its
intended destination by routing the signal around obstacle and radio
dead spots.

ZXT-120 supports Network Wide Inclusion (NWI) and Explore
Frames. It also supports Z-Wave networks with multiple gateways and
controllers. Like every Z-Wave accessory, user will need to include the

3

ZXT-120 into their Z-Wave network using the primary controller.
Then, the user can use either the primary controller or secondary
controller to configure and setup the ZXT-120 using Z-Wave’s
configuration command class. Once the configuration and setup is
complete, the controller can use Z-Wave’s “Thermostat commands
class” to control their IR-controlled air-conditioner with the ZXT-120.

Controller and Gateway Requirements

The ZXT-120 is architected to work with any Z-Wave compliant
controller or gateway supporting the following Z-Wave commands.

- Configuration Command Class

- Multilevel Sensor Command Class

- Sensor Configuration Command Class

- Thermostat Command Class

 Thermostat Mode Command Class
 Thermostat Fan Mode Command Class
 Thermostat Set-point Command Class

Built-in IR code library

The built-in IR code library enables the ZXT-120 to work with any Z­Wave compliant gateway and controller. Gateway and controller will
not need to have any knowledge related to IR control code. It also
eliminates the needs of complicated set up procedures and proprietary
Z-Wave commands to configure the system. The IR code library
supports various brand name air conditioners found in the today’s
market. User can use his controller or gateway to send a 3 digits AC IR
code number (include the brand selection) using standard Z-Wave
configuration command.

Devices and nodes are all terms to describe

To take a device out of a group, scene or
association group while that device still
exists in the same Z-Wave network.
A collection of Z-Wave devices is controlled
by primary and secondary controllers
operating on the same system. A Z-Wave
network has its own unique ID code so that
controllers not in the network cannot control
the system.
The first controller is used to set up your
devices and network. Only the Primary
Controller can be used to include or delete
devices from a network. It is recommended
that you mark the primary controller for each
network for ease in modifying your network.
A controller containing network information
about other devices within the network and is
used for controlling devices. Secondary
controller is created from the Primary
Controller and cannot include or delete
devices to the network.
A controller containing network information

used for controlling devices. Inclusion
controller is created from the Primary
Controller in a SIS enabled Z-Wave network.
Inclusion Controllers have the ability to add
and remove devices from the network.

ZXT-120 Operations

Before using the ZXT-120, please read the [INSTALLATION] if it is
needed to mount the ZXT-120 to a wall. Power up the ZXT-120 by the
USB Power 5Vdc or Dry battery AAA x 3pcs.

• Plug-in 5Vdc power into the USB socket if operated at Always

Listening mode. Or

• Install 3xAAA batteries if operated at FLiRS mode.

• Please refer to the section of [MOUNTING PROCEDURE].

• Remove the battery cover on the back of your ZXT-120 battery

chassis.

• Mount the battery cover into the main unit with 2 screws.

• Check the polarity of the batteries and the "+/-" marks inside the

battery compartment.

• Insert the batteries.

• Push the battery cover and main unit back in place.

L CAUTION (battery and power adaptor safety)

− Use new batteries of the recommended type and size only.

− Never mix used and new batteries together.

− To avoid chemical leaks, remove batteries from the ZXT-120

if you do not intend to use the remote for an extended period
of time.

− Dispose of used batteries properly; do not burn or bury them.

(Please carefully read through the following then store the manual for
future reference.)

Z-Wave Remote Control

1) Select your operation mode; please refer to “Listening Mode”

section.

2) Include or Exclude

control network with your primary controller.

- Refer to your primary controller instructions to process
the inclusion / exclusion setup procedure.

- When prompted by your primary controller, click once on
the PROG button.

- The primary controller should indicate that the action was
successful. If the controller indicates the action was
unsuccessful, please repeat the procedure.

3) User can use either the primary controller or secondary controller

(should support configuration command class) to setup the ZXT­120 AC code by the parameter 27
code library), please refer to code list for the parameter value
setup your AC control code.

4) Once the configuration and setup were completed, the controller

can use Z-Wave’s “Thermostat commands class” to control their
IR-controlled air-conditioner with the ZXT-120.

5) You can record down your device code under the below table for

future reference after setting up the ZXT-120 correctly.
