not always be correct (if it is measured during the deactivation cycle of 6 minutes).

optional remote temperature sensor is connected in THM4 of the PCB of the indoor unit or if there is RCS remote sensor.
When there are selected a combination of different sensor it will calculate the average between them. When nothing is
selected, it is forced to use the Tin value.
