hello all,
we have a Mitsubishi Mr. Slim (PKA-A36FAL) that since installation seems to have a thermostat issue. specifically the thermostat is reporting that the room temperature is about 16 degrees (F) warmer than reality. the error, seems to be consistent, always about 16 degrees off. for example, the thermostat is currently reporting that the room is at 83 degrees when a bulb thermometer reading at the same location as the thermostat reports 67 degrees. the AC works great, the problem is that the thermostat and real room temperature are quite different so i have to compensate by setting the thermostat fairly high otherwise the cooler runs constantly and the room becomes too cold.
the unit is brand new and under warranty, but i am having difficulty getting a timely response from the installers. when we last talked, the installer indicated that there may be thermostat calibration routine that we can perform that would rectify the situation. can anybody instruct me on home to perform the calibration (not detailed in the operation manual i was given) or provide any other advice on my situation?
thanks, alex
