What do you need?

Niko requirements

Your Niko Home Control installation meets the following requirements:

• It has a wireless smart hub or a connected controller II.

• It is configured with the most recent programming software.

Depending on the basic modules of your Niko Home Control installation, you need to install the following additional products:

Bosch requirements

Your system meets the following requirements:

• It is a heat pump or heat pump boiler with Smart Grid Ready contacts.

• It is configured to allow correct Smart Grid Ready contact use.

Wiring diagrams

Connecting heat pumps

Via potential-free contacts:

Switching module	Connected double switch
	*230V to potential-free contact module (e.g. Finder 22.32.0.230.1xx0)

Smart Grid 1 and 2 (as indicated in the wiring diagrams) correspond to the the following Smart Grid Ready contacts on your heat pump:

Programming energy-saving routines for heat pumps

Configure the energy-saving routines for the heat pump via the Niko Home Control programming software. For more information, see Solar mode and Peak mode.

You can use the following programming example as inspiration or as a starting point: Making a heat pump respond to excess electricity

It is advised to configure the parameters as follows:

Solar mode

• Level of excess solar energy that activates the device (one of the following options):

  • 50 % of the power of the heat pump compressor

  • 25 % of the thermal capacity of the heat pump (often the name of the heat pump contains a reference to this thermal capacity)

• Minimum activation duration: 1 hour

Optionally: Define the latest start time and duration to ensure that the device is activated before the peak hours.

Peak mode

• Maximum power consumption (one of the following options):

  • 100 % of the heat pump compressor power

  • 50 % of the thermal capacity of the heat pump (often the name of the heat pump contains a reference to this thermal capacity)

• Peak target value: the maximum power level that should trigger the devices to turn off

• Peak mode type:

  • Predictive (capacity tariff in Flanders)

  • Direct
