1) Unit at full load - Evaporator water = 12/7°C
2) Unit at partial load (automatic partialization)
3) With electronic low ambient temperature control (std), unit at full load and motionless external air
4) With electronic low ambient temperature control (std), unit at partial load and motionless external air
5) With electronic low ambient temperature control (std), unit at partial load with air speed 1m/s
Note: The electronic low ambient temperature control with inverter is recommended for temperatures lower than 5°C
