  • Page 28 3-7 Heating-run mode 3-7-1 Temperature compensation The temperature compensation is 5º in heating mode. For example, if the set temperature is 25℃(77°F) by the remote control, when the room temperature is detected with 31℃(88°F), the compressor will turn off. The main reason is that the hot air is condensed at the top of the house.
