6.5 Setting up the power consumption control
▪ The power consumption control:
- Allows you to limit the power consumption of the entire system (sum of
outdoor unit, indoor unit and backup heater).
- Configuration: Set the power limitation level and how it has to be achieved via
the user interface.
▪ The power limitation level can be expressed as:
- Maximum running current (in A)
- Maximum power input (in kW)
▪ The power limitation level can be activated:
- Permanently
- By digital inputs
NOTICE
Set a minimum power consumption of ±3.6 kW to guarantee:
▪
Defrost operation. Otherwise, if defrosting is interrupted several times, the heat
exchanger will freeze up.
▪
Space heating and DHW production by allowing the backup heater step 1.
6.5.1 Permanent power limitation
Permanent power limitation is useful to assure a maximum power or current input
of the system. In some countries, legislation limits the maximum power
consumption for space heating and DHW production.
