Power meter types

Single-phase power meter.

5.6 Setting up the power consumption control

You can use the following power consumption controls. For more information

about the corresponding settings, see "9.4 Advanced configuration/

optimisation"[4127].

# Power consumption control

1 "5.6.1Permanent power limitation"[444]

▪ Allows you to limit the power consumption of the entire heat pump

system (sum of indoor unit and backup heater) with one permanent

setting.

▪ Limitation of power in kW or current in A.

2 "5.6.2Power limitation activated by digital inputs"[445]

▪ Allows you to limit the power consumption of the entire heat pump

system (sum of indoor unit and backup heater) via 4 digital inputs.

▪ Limitation of power in kW or current in A.

5.6.1 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.

b Actual power input

Setup and configuration

▪ No additional equipment needed.

▪ Set the power consumption control settings in [A.6.3.1] via the user interface (for

the description of all settings, see "9Configuration"[4108]):

- Select full time limitation mode

- Select the type of limitation (power in kW or current in A)

- Set the desired power limitation level

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.
