Some remote controller is equipped with a thermal sensor (Such remote controller has the function of man-machine communication. For details, refer to the section for the remote controller). In addition, there is a thermal sensor at the indoor air inlet.
- Page 35 3.9 Cold air prevention In the heating-run, to prevent the indoor fan from blowing cold air, the indoor fan will stop or run slowly until the coil is warmth. 3.10 Mode interfere For the reason that all indoor units use one outdoor unit, outdoor unit can only run with same mode(cooling or heating), so, when the mode you set is different from the mode that outdoor is running with, mode interfere occurs.
