Qunda KT-1000 universal air-cond remote control

The remote control of my Panasonic air-cond seems to have difficulty sending sleep timer signal to the wall unit. The air-cond remote control replacement unit from Panasonic will probably cost me a bomb (its official price is more than RM80).

I bought this Qunda KT-1000 universal air-cond remote control at RM19 including batteries after bargain in the market.

This air-cond remote control can do most of the air-cond settings and supports 1028 air-cond remote control signal codes. The picture below shows all its available setting buttons after its cover slided down.

It claims to support 98% of air-conds in the world, including brands such as Alpin, Aucma, Aux, Banshen, Boerka, Carrier, ChangHong, Chigo, ChoFu, ChunLan, Corona, Conrowa, Consul, Daewoo, Daikin, Doctor, DongBao, DongXinBao, Electrolux, Frestech, Fujitsu, Funai, GuQiao, Galanz, Glee, Goldstar, Gree, Haier, HiSense, Hitachi, HuaBao, Huake, HuaMei, HuaLing, HuiFeng, HuiKang, Hyundai, JDC, JiangNan, JinDa, JinSong, Johson, KangLi, Kelon, Klimatair, Kongka, LG, LiangYu, Little Duck, Loren-Sebo, Macquay, Midea, Mitsubishi, Moritz, Panasonic, National, Panda, Philco, Proton, Raybo, Rowa, Sabro, Saijo Denki, Sampo, Samsung, Sanyo, Sasuki, ShanXing, Sharp, ShengFeng, Shinco, Shuanglu, Shuai Kang, Songge, Sova, Summer, SunDurg, Swan, Tadiran, Tatung, TCL, Teco, Tiandi, Micom, Toshiba, Trane, Uni-air, Weili, Whirlpool, Xileng, Xinle, Yangzi, Yinyan, York, ... which most of the brands I have never heard before.

I found that there are more than 1 signal codes able to control my Panasonic air-cond. However, all the codes which can be used to control my Panasonic air-cond are unable to do timer setting to the air-cond. The air-cond can respond accordingly to on/off switch, mode settings, temperature settings, air swing settings, fan settings, etc. but no respond to timer setting.

So, my problem haven't solved yet.
