Remote thermostat for Fujitsu mini-split ?
I recently had a Fujitsu mini-split (AOU15RLS3H with ASU15RLS3) installed in a 24*36 foot room in Vermont. It is working well except that the temperature in the room not far from the unit is usually about 5 degrees below the setting on the remote. I have found two ways to get the temperature to the desired level: (1) Increase the setting on the remote or (2) set the fan not to automatic but to high. Neither of these solutions is ideal.
(Note that it is not in “economy” mode, the people sensor is off and the fan louver is pointing down.
It appears to me that the problem is that because the temperature sensor is in the unit itself instead of on the wall, the unit comes on and heats the air near the unit then shuts off or goes into almost an idle stage. The problem is not insufficient capacity, the problem is that the unit seems to think that the room is warm enough when it is not.
One solution might be to install a wired thermostat if the temperature sensor is in the remote. Can I do that?
Or is there a better solution?
Or am I missing something that should be obvious? And why do they put the thermostat in the unit instead of on the wall as in other heating systems? Is this guy correct?
Thanks for any suggestions,
