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 

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 

learnt data of 26  C Cool to air conditioner.  When user press Heat on gateway 

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)
