I can’t quite see the icons on ur photo of the controller, you do need to make sure that you have the correct mode selected out of cooling, heating or auto. When you switch the unit on, if it is showing as 18degrees and auto is selected, the unit will run in either cool or heat to try and get the surrounding air to reach this temperature (in assuming that your unit has cooling & heating options - some are cooling only). Once this temp is reached the unit should go off, and will kick in every so & often to try to maintain this temp.
If you have heat or cool showing on the display, then the unit will still try to reach 18 degrees by either of these modes - however if cooling icon is showing the unit may not kick in if the room temp is below 18, as it is impossible to cool air to a higher temp!
I am a bit puzzled why your remote is actually showing 18degrees stepping, this is quite cool for a normal comfortable temp, do you find this to be quite cold during evening time or when the sun goes down?
