Why the COOL operation Mode is Blinking at my Mitsubishi Electric Remote Controller

0010
As for Mitsubishi Electric Air condition units,
Here’s why the operation mode is blinking:
For multi of VRF heat pumps systems
The first indoor unit you operate will determine the system state.
It will blink when you try to simultaneously operate in deafferents modes.
To fix it just turn off the indoor units and turn it on again at cooling mode.
In more detail:
When you have Mitsubishi Electric Multi system (MXZ series)
Or
Mitsubishi Electric Heat Pump VRF/Mini VRF system (PUHY/PUMY series)
That can connect to two of more indoor units,
The operation of the indoor unit that operates first will determine the working state of the system.
When you try to operate two or more indoor units simultaneously one for Heating and one for Cooling
The operation mode icon will blink.
In order to solve this, turn OFF all the indoor that heating and turn ON the indoor unit for cooling.
