Thermostat Set Point and Room Temperature
我有两个房间，每个房间不到300平方英尺，一个15K富士通单元连接到一个外部单元。我知道一个带有短管的单个单元可以处理两个房间，但我们想要每个房间的恒温器，即使这意味着单元的循环效果比应有的。无论如何，无论外部温度如何，这两个房间通常都比其恒温器上的设置低4至6度。
The outside temperature is only in the 30’s and obviously they have plenty of capacity to heat. If it gets colder outside they will produce more heat but still not enough to get up to the thermostat setting. They are not in “economy” mode. I have used an infrared thermometer and determined that the temperature above the unit is much below the thermostat setting. Somehow the units seem to decide that the room is warm enough and they don’t need to put out enough heat to warm the room.
Any ideas about why this might be happening?
Thanks for any suggestions,

Their internal tstat may be calibrated wrong?
Can you just set the t-stat for 4-6 degrees higher and get the comfort and temp you want?
Is the unit running and not providing enough heat? Or is it not running even though the thermostat should be telling it to run?
The green power light is on and it does produce heat, but it stops giving the heat when the temperature gets to within 4-6 degrees of the room temperature. If I set the thermostat for 76 degrees then it will usually be around 70. But I sort of doubt the problem is with the internal thermostat since it is true of both units.
如果您仍然有T-Stat的说明手册，请检查并查看其是否具有集合或可调节的差分设置。在房屋周围使用几个温度计，以查看它们是否与T-Stat本身的温度读数相当。T-Stat的位置可能会产生一定的影响，例如。是在阳光或阳光晴朗的房间，在外墙上，靠近供暖单元/远处...
Try using a fan, or ceiling fan if you got one, to mix up the air in the room to even things out and see if that has any effect. A heat supply in a small area works a lot different than say baseboards that create circulation along a greater portion of the room.
To my ear the way most mini splits sense the rooms temp from the air moving thru the unit seems unlikely to get a good sample that seems to line up with your complaint.
Would this remote sensor be compatible with your unit?

Based on your description this can be completely solved by adjusting the temperature offset. Look in your manual. There's separate adjustments for heating and cooling. If it turns out that the temperature is correct sometimes but not other times, that would likely be due to the temperature being measured inside the head rather than a more central thermostat. You can get aftermarket wireless solutions for this. I have a Sensibo branded unit which works fine.
