Remeha - Wired connection - Energy (via SG Ready contacts)

What do you need?

	In short	Extra information
General	Specific electrical wiring is required.
	Your Niko Home Control installation meets the following requirements: It has a connected controller II. It is configured with the most recent programming software (version 2.17 or higher).	You need the following if you want to use the Niko Home Control energy-saving routines (e.g., solar or peak mode): a Niko Home Control switching module (550-00103 or 550-00106) with two outputs OR a wireless bridge (550-00640) and one connected double switch (552-721X2) in combination with potential-free contact modules (e.g. Finder 22.32.0.230.1xx0) The connected double switch can be placed on a DIN rail using a modular holder (e.g. Legrand 412950)
	Your Niko Home Control installation meets the following requirements: It has a wireless smart hub. It is configured with the most recent programming software (version 2.17 or higher).	You need the following if you want to use the Niko Home control energy-saving routines (e.g., solar or peak mode): one connected double switch (552-721X2) in combination with potential-free contact modules (e.g. Finder 22.32.0.230.1xx0) The connected double switch can be placed on a DIN rail using a modular holder (e.g. Legrand 412950)
	Your partner system meets the following requirements: It is a Remeha heat pump or heat pump boiler with Smart Grid ready contacts.	The partner system has to be configured to allow correct SG-ready contact use.

The below table shows several options on how you can use Niko Home Control with your Remeha system and enable Niko routines (solar and peak mode).

It is advised to configure the parameters in peak mode and solar mode as follows:

Level of excess solar energy that activates the device: 50 % of the heat pump compressor power
Minimum activation duration: 1 hour

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

Maximum power consumption: 100 % of the heat pump compressor power
Peak target value: the max. power level that should trigger the devices to turn off
Peak mode type:
- Predictive (capacity tariff in Flanders)
- Direct
