Z-Extender ZXT-120
(Z-Wave-to-AC IR Extender)
Introduction
The ZXT-120 is a Z-Wave to IR extender for air-conditioner (AC), (Figure 1), it works with
any Z-Wave compliant gateway or controller by translating Z-Wave Thermostat
Commands to AC IR control code. User can select the IR code from the built-in code
library of ZXT-120, or use learning function, by using Z-Wave Configuration Commands
according to the parameter table. ZXT-120 is also with built-in temperature sensor which
allows gateway or controller to get the current room temperature.
ZXT-120 can be configured as either "Frequently Listening Routing Slaves" FLiRS (if
you are using battery) or "Always Listening" (if you are using 5Vdc adaptor) before
inclusion process. Refer to Glossary for definition of "FLiRS" and "Always Listening"
mode.
ZXT-120 supports Network Wide Inclusion (NWI) and Explore Frames. It also supports Z-
]Wave networks with multiple gateways and controllers. Once the configuration and setup
is complete, the gateway or controller can use Z-Wave "Thermostat commands class" to
control their IR-controlled air-conditioner through the ZXT-120.

Controller and Gateway Requirements
The ZXT-120 can work with any Z-Wave compliant controller or gateway supporting the
following Z-Wave commands.
- Configuration Command Class
- Multilevel Sensor 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 supports most of the popular air conditioner brands in the
market. Z-Wave gateway and controller does not need to have any IR control code
knowledge. User can use Z-Wave controller or gateway to select the IR code according to
the ZXT-120 code list separately provided through Z-Wave configuration command.
Glossary
Device or Node Devices and nodes are all terms to describe an individual Z-
Wave device. These are all interchangeable when setting up
your Z-Wave network.
Inclusion Add a Z-Wave device to the network.
Exclusion Delete a Z-Wave device to the network.
Remove To take a device out of a group, scene or association group
while that device still exists in the same Z-Wave network.

4
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.
Primary
Controller
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.
Network Wide
Inclusion (NWI)
Network Wide Inclusion (NWI) enables both end-user friendly,
Plug and Play like Z-Wave network installation as well as
professional installation scenario where the inclusion process in
terms of time will be reduced significantly. NWI is a feature
supported by a new frame type named Explorer which enables
the Z-Wave protocol to implement Adaptive Source Routing.
FLiRS Mode FLiRS is abbreviation for "Frequently Listening Routing Slave".
FLiRS mode is targeted for battery operated applications and
will enter sleep mode frequently in order to conserve battery
consumption. The response to Z-Wave command is not as
quick as Always Listening Device. Normally there is 1-2
seconds latency.
Always Listening
Mode
Always Listening mode is targeted for AC power operated
applications and it 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. The response to Z-Wave command is
immediate.

After all learning completed, user can go back to the ZXT-120 control page on the
gateway for normal operation.
- On the gateway UI, user can only use the temperature range from the mapping
table, OFF, ON(RESUME), COOL, HEAT, DRY, If user press the button of FAN, or
other function on the gateway UI which is not listed in above table, ZXT-120 will
not respond.
- If user only learnt ON, OFF, or part of the settings according to the above table,
ZXT-120 will send the learnt data to the air conditioner only. For example, user
o o
only learnt ON, OFF, 22 C Cool, 24 C Heat, ZXT-120 will not send IR data to air
o
conditioner if user set 27 C Cool on the gateway.
o o
- ZXT-120 has been pre-defined default cool at 26 C, default heat at 22 C, when
user press Cool on gateway without setting temperature, ZXT-120 will send the
o
learnt data of 26 C Cool to air conditioner. When user press Heat on gateway
o
without setting temperature, ZXT-120 will send the learnt data of 22 C Heat to air
conditioner.
- There is only one code for dry mode, user can set it at any preferred temperature.
- User can still use gateway to set up scene and schedule with ZXT-120, for
o o
example, to have AC turn on at 23 C every day at 7pm, 25 C at 11pm. Just
make sure the set code is learnt.
- The learning mapping table is for split air conditioner which remote control is with
LCD display. For window type air conditioner (which remote control is without LCD
display), the mapping table with temperatures do not apply, due to different type of
IR control protocol. However, user may still use the OFF, or ON/RESUME, DRY
key for learning. (Because the POWER key on the original remote without LCD
display is toggle, user can choose either ON key, or OFF key to learn Power key,
after learning is done, press once to turn on the air conditioner if the air
conditioner is OFF, press once to turn off if the air conditioner is ON)
