Hello Friends,

I have a 1.5 ton hitachi split ac. model: rau318ksd/2012. Cooling of the AC is good.

However the problem is, the AC is not regulating the temperature. Whether I maintain the temperature as 18 or 30, the cooling is same. Even at 30 the compressor is constantly on and the room gets chilled. Also whenever I switch on the AC the compressor gets on instantaneously without any delay. Is this normal?

I have read the entire manual and I operate the AC in 'auto' or 'cool' mode without any other features enabled. I think the problem is with installation of indoor unit. Is there something I can do on my own to fix the problem?

Any suggestions are welcome.

Thank You.

There may be a problem with the thermostat , call in Hitachi service and get it checked.
