Z-ExtenderTM 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.
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 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.

Setup and Operations Before using the ZXT-120, please read the [INSTALLATION] if you need 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.
How to switch ZXT-120 listening mode from "Always Listening" to "FLiRS" (or vice verse) Step Setup Key LED Indication Status on ZXT-120 1 Press and hold the PROG button on the ZXT-120 for around 5 seconds - LED turns ON after PROG key hold for 5seconds 2 Release the button and then press the PROG button 3 times within 2 seconds - LED flashes twice then stay off (ZXT-120 set in FLiRS mode) OR - LED flashes four times then stay off (ZXT-120 set in Always Listening mode) Inclusion/Exclusion Step Setu
IR Code Selection ZXT-120 is with built-in IR AC code library, user may select the IR code using Configuration Command Class. Step Setup Key 1 After included ZXT-120 to Z-Wave controller or Gateway, go to device setup for configuration on gateway or controller. 2 Input parameter number "27" and parameter value (please look up the code list of ZXT-120 according to your AC brand). Then complete the configuration process.
Important Information - Different brand or model of air conditioner has different function. For example, some air conditioner only support temperature set from 18 o C - 30 o C, if user set 17 o C on gateway, ZXT-120 will not respond. - There are more than 1 code for each brand, some does not support heat, if user selected a code that does not support heat but the original air conditioner supports heat function, please continue to try next code until the correct one is selected.
Step Setup Key LED Indication Status on ZXT-120 2 Look up below mapping table (value 0-22) for learning, and decide the IR setting you intent to learn next. For example "22 oC, cool" which matches value "5" (IR code to be learnt will locate at "5" in ZXT-120). Set your original air conditioner remote at "22 oC, cool" and turn it off. (Besides temperature and mode, you may set other desired settings, such as Fan, Swing etc.
When you encounter problem, check followings: - Make sure your original remote is switched to power off. Press the key on original remote before learning mode timeout. Keep away from incandescent light and direct sunlight during learning. Make sure IR Transmitter of your original remote alight with learning diode of ZXT120, you may also slight adjust closer or further away the distance of two devices. Some of remotes the IR transmitter in hidden behind lens and may not installed center of remote.

Important Information 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.
Reset ZXT-120 to factory default Press and hold "PROG" button for 10 seconds on ZXT-120. During the key hold period, RED LED lights up at around 5 seconds, then, it will flash twice until reset process is completed at around 10 seconds. Information - This reset step will not affect the listening mode of ZXT-120, user should refer to "Listening Mode" section if you want to change the listening mode.

Installation Mounting the ZXT-120 to a wall MOUNTING LOCATION PRECAUTIONS - Before mounting, check the material and structure of the mounting location. If the location does not have the proper material or structure, the ZXT-120 can fall and cause injuries. - Use commercial items that best match the wall structure and material for the screws and other fixtures. - Do not mount near a kitchen counter, humidifier, or other location in which it can be exposed to smoke or steam.
MOUNTING PROCEDURE The ZXT-120 can be mounted to a wall or wooden racks using the two key holes in the bottom case. Note 1: The reception sensitivity varies depending on the antenna direction. Note 2: Before mounting to a wall, be sure to fully read the precautions. 1. Obtain two screws suitable for the wall strength and material. The screw size is shown in the figure below. MIN. 6-8mm (3/16 - 3/18ins.) 3-4mm(1/8 - 3/16ins.) MIN. 3mm(1/8ins.) 2.
3. Insert the ZXT-120 key holes onto the two screws mounted to the wall, and then slide downward to secure in place. 4. After securing the ZXT-120 to the wall, connect the USB Power or batteries and IR emitter cable to the ZXT-120. Note 1: Check that the ZXT-120 is firmly secured to the wall. Note 2: Insert USB plug or batteries and IR emitter cable so that they are firmly connected to the ZXT-120. 5. When removing the ZXT-120 from the wall, lift up the ZXT-120, then pull it towards you. 6.
Wireless Information This device has an open-air line-of-sight transmission distance of 25m which complies with the Z-Wave standards. Performance can vary depending on the amount of objects in between Z-Wave devices such as walls and furniture. Every Z-Wave device set up in your network will act as a signal repeater allowing devices to talk to each other and find alternate routes in the case of a reception dead spot. Radio frequency limitations: 1. Each wall or object (i.e.
Frequently asked questions Q Why won't my ZXT-120 work with the Z-Wave devices I purchased from another country? A Due to different countries regulations Z-Wave products from different regions are set to different frequencies. Before purchasing new devices make sure you have checked that the device is compatible in your region. Q How do I know which product is compatible with my ZXT-120? A ZXT-120 should work with any Z-Wave controller or gateway that has control capability for "Thermostat" devices.
Q Can I use 2 or more ZXT-120 in my house? What is the max. units if yes? A Yes and it is very depend on the capability of gateway / controller. For example, gateway can supports up to 8, 16 or 32 ZXT-120 in a network. Q How to avoid the IR interference if I am using 2 identical air-conditioners in same location but want to control them individually? A User can disable the Surround IR Output function, connect the external IR emitter and aim it at the specific AC unit.
