fujitsu in cool at cold whether

[Yuri B.]

Hello.
Maybe somebody know the minimal outside temp for the AOYA14LAC2 multi split in cooling mode at winter?
(I mean one below which operation is blocked.)

Someone here wants to make it run in the server room with the outside temp of about -15C. If I cheat the probe, also make the fan cst control, what may happen to the compressor?

You need to install compressor crancase heater (i would use self regulating cable). Also, I would fit some electrical heaters ( perhaps 2-3 kW) at outdoor unit heat exchenger to add necesary heat when condensation temperature(pressure) falls below 35°CST controled by some pressure stat. Or again use some amout of self regulating heating cable at heat exchanger.
That way, I suppose, compressor will be safe, but than again, if you fooll outdoor air sensor , control functions wuold be having false data and, maybe, could not properly lead operation of AC.
