maintain set value (default 18°C)
• Delta T water in-out. Unit will try to maintain
settled value (default 6°C)
• By heating curve. Possible to choose from 5
heating curves.

1. By differential pressure on duct (VAV);
2. By constant air flow (CAV).
Note:
The regulation type can be selected from Main
menu In Unit settings.

In “Summer mode”, when the ventilation process is
switched from the unit to fire/smoke fan, regulation
will be carried by differential pressure on duct.

1. Antifreeze prevention helps to protect evaporator
from icing and saves energy not letting
compressor work at very low evaporation
temperatures.
2. High pressure prevention helps to protect
compressor from very high condensing
temperatures.
Note:
It is strongly recommended to keep factory settings
for proper and safe operation.
