IR Controller Remotech ZXT-120


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.

Product Description

ZXT‐120 can be configured as either “Frequently Listening Routing
Slaves” (FLiRS) or “Always Listening” node after exclusion process
(before inclusion process).
FLiRS node type is 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 for the needs of fast response
application. It works 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 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 “Thermostat commands class” to control
their IR‐controlled air‐conditioner through the ZXT‐120
