I have a VERTIS Classic AC (A TATA product), but I lost its remote control due to which it is not possible to run AC, while it is sweating hot here.

Please tell me how to run AC without remote device.

I shall feel obliged.

You will need a new remote control. This very poorly designed product has no other way to turn on unit unless you go into it and use jumper wires on it. You live a country that has almost no electricity, I understand, due to the closing of many coal plants as they are going to do here, too.
