Heat pumps: Wiring diagrams for energy-saving routines (using SG Ready contacts)
The below table shows several options on how you can use Niko Home Control with your Viessmann heat pump system and enable Niko routines (solar and peak mode).
When using Viessmann Vitocal with W01C-control:
Connect the Smart Grid Ready 1 with W01C-control connector contact 216.1 (input C)
Connect the Smart Grid Ready 2 with W01C-control connector contact 216.4 (input D)
When using Viessmann Vitocal with One Base:
Connect the Smart Grid Ready 1 with one-base connector contact 143.4 (input C)
Connect the Smart Grid Ready 2 with one-base connector contact 143.5 (input D)

Heat pump boilers: Wiring diagrams for energy-saving routines (using SG Ready contacts)
Heat pump boilers usually have only one photovoltaic contact. You only have to connect the Smart Grid Ready 2.
The below table shows several options on how you can use Niko Home Control with your Viessmann heat pump boiler system and enable Niko routines (solar and peak mode).
When using Viessmann 060-A :
Connect the Smart Grid Ready 2 with the F input on the Viessmann 060-A (potential-free connector contact).
When using Viessmann 262-A :
Connect the Smart Grid Ready 2 with the S input on the Viessmann 262-A.

Settings for energy-saving routines (using SG Ready contacts)
To view SG-ready programming examples, please see Niko Home Control programming examples.
It is advised to configure the parameters in peak mode and solar mode 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 max. power level that should trigger the devices to turn off
Peak mode type:
Predictive (capacity tariff in Flanders)
Direct
Niko routine | Smart Grid Ready status | Niko Smart Grid output contact | Setting |
