One of the touch screens of one of the A/Cs of the logistics floor

The A/Cs were set to cooling, despite it is winter and it is cold, so I switched them to ventilating and set the fan speed to maximum.
One of the logistics workers said me that they have no windows in the offices, so they are sweating because it is hot there, and I said him that because it is winter now, even ventilation may supply cold air.
