Remote wont turn on the aircon for Conia CA9001....have replaced batteries. We have 5 Conia aircons and the remotes only work on 1 unit

Infra-red sensors are available at all electronic spare part selling shops. http://electronicshelponline.blogspot.com/

Make sure the batteries in the remote are good. Reset the aircon and the remote and try again. If not working, need to be fixed.

There may be a switch around the outdoor unit of the aircond for switch off.

FROM THE AIRWELL RC-4 REMOTE CONTROL MANUAL

NOTE THE COMMENT ABOUT THE RESET AND THE SIMULTANEOUS SELECTION OF THE + - SET and CLEAR BUTTONS to effect a reset after replacingg batteries

HOW TO INSTALL BATTERIES Remove the lid in the rear part of the remote control unit.
Insert two AAA alkaline batteries of 1,5 V-DC. Make sure the batteries point in the direction marked in the battery compartment.
The batteries last about six months. Depending on how much you use the remote control unit. Remove the batteries if you do not use the remote control unit for more than one month. Press the +, -, SET and CLEAR buttons together after batteries replacement.
(This operation allows you to reset correctly all the programs. The remote control unit is to be set up again).Replace the batteries when the remote control unit lamp fails to light, or when the air conditioner does not receive the remote control unit signals.
The batteries of the remote control contain polluted substances exhausted batteries must be disposed according to the laws in force.

Lift indoor unit cover and remove DC wire from display sensor. After 3 minutes again plug it and close the door. Now you try with your remote. If still problem, check your remote through cell phone camera by pressing any button in remote. If ultra light is visible thr' camera, remote is o.k. If remote is o.k, repair/replace PCB. Thanks.

Possibly weak batteries???

Does your remote have batteries? If yes change them. Somewhere on the unit there should be a selector switch, put it into test and manually lower the thermostat setting

i had the same problem and i managed to find a universal remote control from JARCAR Electronics. Model of the remote: Digitech AR-1729. It doesn't list Conia as compatible but I managed to gain control of the aircon using the code: 291. For some reason when you press the power button on the remote, it's like your double pressing the on button so the aircon switches on and off quickly. You need to press the power button on the remote quickly and move it from reception before it powers down the unit again. At least I have control of the aircon again and I don't have to put up with these humid hot days in melbourne... Good Luck.

You should change the remote sensor receiver unit on the unit.
