TM Z-Extender ZXT-120 (Z-Wave-to-AC IR Extender)IntroductionThe 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-120.2Figure 1 ZXT-120
3Controller and Gateway RequirementsThe 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 ClassBuilt-in IR code libraryThe 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. GlossaryDevice 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.
4Z-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 ControllerThe 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 ModeAlways 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)Important Information13

21Wireless InformationThis 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.: refrigerator, bookshelf, large TV, etc) can reduce the maximum range of 20m by up to 20 to 30%.2. Plasterboard and wooden walls block less of the radio signal then concrete, brick or tile walls which will have more of an effect on signal strength.3. Wall mounted Z-Wave devices will also suffer a loss of range if they are housed in metal junction boxes which could also reduce the range by up to 20 to 30%.Maintenance1. Do not expose your unit to dust, strong sunlight, humidity, high temperatures or mechanical shocks.2. Do not use old and new batteries together as old batteries tend to leak.3. Do not use corrosive or abrasive cleansers on your unit.4. Keep the unit dust free by wiping it with a soft, dry cloth.5. Do not disassemble your unit, it contains no user-serviceable parts.
All Z-Wave products also come with the Z-Wave logo.Frequently asked questionsQ 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 the USB port to configure ZXT-120?A No, the mini USB port only provides an alternative option for user to power the ZXT-120.Q Do I need an electrician to install Z-Wave products in my house?A Installation can be simple. In some cases all you need to do is mount the ZXT-120 to a wall or wooden racks. You also can place the ZXT-120 on the desk and power it with dry cell batteries.Q How to select my air-conditioner IR code from ZXT-120?A You should refer to the code list and look into the brand and try the code no. sequentially until you find the right code. You can record down your device code under the table for future reference after setting up the ZXT-120 correctly.Q ZXT-120 is working on top and 4-directions IR output, but there is no response on the IR emitter socket, why?A ZXT-120 supports two IR power levels for the external IR emitter to avoid saturation of the IR receiver. You can set the IR output power level by the Parameter Table value (normal or high power mode) or adjust the position of your external IR emitter.22
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. The operating distance of external IR emitter is around 100cm (High power mode) and 50cm (Low power mode) but it is also depends on the sensitivity of the IR receiver.23External IR emitter cable
