Temperature value range of AC is incorrect


**Describe The Bug:**
Possible temperature values are wrong. The AC supports values as low as 16 degrees Celsius, however in Apple Homekit 18 degrees Celsius is te lowest temperature possible. It isn't possible to set the temperature to 16 using a scene through Home Controller. It IS possible to set the temperature to 16 using the LG Thinq app.

**To Reproduce:**
Set the temperature of the AC to any temperature below 18.

**Expected behavior:**
The temperature is set to the requested value
It is possible to select the lowest value of 16 through homekit and the Homebridge dashboard
