Power limitation is also useful in combination with an energy management system.
The power or current of the entire Daikin system is limited dynamically by digital
inputs (maximum four steps). Each power limitation level is set via the user
interface by limiting one of the following:
▪
Current (in A)
▪
Power input (in kW)
The energy management system (field supply) decides the activation of a certain
power limitation level. Example: To limit the maximum power of the entire house
(lighting, domestic appliances, space heating...).
