fujitsu inverter doesn't start when the outdoor temp is below zero
hello my friends!
Does anyone know why a fujitsu inverter ,24000 btu -R 410 ,doesn't start operating when the ambient temperature is below 0 Kelsium?
During the day when the temperature rises it operates normaly as usual in heating mode.
Thanks a lot!

Faulty outdoor sensor?

Re: fujitsu inverter doesn't start when the outdoor temp is below zero
maybe, but it generates me many questions why this is always happening at the dawn when temperature is below zero.I suppose that the control cuts the system as a protection from icy conditions.
However, this is not correct since the system is inverter (designed to operate at low temperatures) and next to fujitsu is installed a daikin inverter split(in another room) that operates without any problem at all.

The moral is Daikin is better than Fujitsu
