Introduction

With evonHOME, you have brought the most up-to-date home automation system into your home. We want to help you with the planning so that your project is easily implemented. Before you dedicate yourself to the detailed information in the documentation, we would like to give you a rough overview of the functionality in an evonHOME system.

Depending on what you intend to control, you will need different evonHOME modules (light module, blinds module …); according to the application or function, there is a range of different modules you can choose from. The autonomous evonHOME modules provide you with centralized functions such as “All Lights Off”. The complete range of control functionality is only available with the CPU module, which enables the configuration and control to be done via smartphone, tablet or PC.

The modules are mounted in one or more cabinets and need to be connected and wired differently to conventional electrical installations. The electrical consumers are connected to the module outputs and one or more switches are connected to the inputs. In contrast to a conventional electrical installation, the switches are not used to directly switch 230V to a consumer, but to control an evonHOME module. Since the laying of empty conduit and the laying of cables occurs at a different time to the installation of the consumer unit and the commissioning of the controls, it is extremely important that the cabling for electrical consumers and switches is planned in detail. Hence the first part of our documentation details with the necessary steps to do this.

Before Installing

Here you will find all necessary information about the installation of your evonHOME.

Planning

You need to consider a few things when implementing your smart home project. If you want, you can determine the following points yourself and go to an evonHOME partner of your choice with the results, or the evonHOME partner can accompany you and advise you through these steps.

In the beginning, there was a plan – what do I want my house to be capable of? Take your house plans and think of the following for each floor and room:

  • Where will the consumer unit be located?
  • Number of electric blinds and what type (standard or 24V with reverse switching?).
  • Number of separate switchable light circuits and what type (standard via load relay, integrated load relay or dimmer function).
  • Number of room temperature regions for temperature control (number of heating circuits per room temperature region is not relevant here).
  • Number of special functions via input and outputs (e.g. doorbell, alarm light, window contacts, presence sensor, camera, audio, …).

First things first: think about what you actually want to control. Don’t worry at this stage about how and when, because all functions can be combined later via the evonHOME app. Just get them connected to the controller (lights, blinds, garden irrigation, doorbell, …).
The evonHOME configuration Excel file enables you to determine your exact module requirements and helps you keep an eye on the costs.

Configuration – EXCEL

You will need a 24V power supply for the modules and a CPU evonHOME Controller (HC-iX800) module for the app control.

Example:
Let’s take a bedroom on the first floor as an example. We will use this example throughout the entire documentation and show the full capability so that we can use it everywhere.

Electrical Cabinet Placement

Depending on space requirements and availability, you can install everything in a central consumer unit or split it up over sub-consumer units. Normally, it is advantageous to combine the cellar, ground floor and outdoors area in a single consumer unit and put the electronics for the first floor in a smaller sub-consumer unit on the first floor. Using sub-consumer units reduces the length of cables and thus substantially reduces the cabling effort and simplifies the feeding in of cables.

You will need a bus extension module for every sub-consumer unit to connect the evonHOME modules to one another. You also need a bus extension module (Sys 1200) each time you start a new row within a consumer unit.

A separate 24 V supply is not always required for a sub-consumer unit. If the power is sufficient, you can route the supply from a previous unit.

Ensure that the GND connection of all power supplies is connected with the protected earth connection (PE).

Example:
Since the bedroom is on the first floor, we will use a sub-consumer unit. The power supply and the evonHOME controller are placed into the main consumer unit and the bus extension and the module for the bedroom in the sub-consumer unit. Both consumer units are connected to each other with the bus cable (CAT5) and the 24V power supply cable.

Blinds

The number and type of blinds to be controlled determines which module is to be used. It doesn’t matter whether the shading element is a roller shade, internal blinds, external blinds, or an awning – the important thing is how it is driven. Use the evonHOME module Blinds module B1144 if the motor has a separate line for UP and DOWN and is supplied with 230V. If the motor has a reversing switch then use the evonHOME module Blinds module B1244. Each of these modules can control two shading elements.

Example:
The bedroom has a window and a balcony door whose shading elements are to be controlled. Both shading elements are equipped with a normal motor (UP/DOWN, 230V). We will therefore plan an evonHOME module B1144, whereby the first output will be used for the balcony door and the second output for the window.

Light Circuit

It is important that you consider the number, function and type of lighting you wish to use for illumination. It is a good idea to draw your lighting circuits on a floor plan and note whether the circuits should be switchable or dimmable. Once you have considered the lighting circuits, the next thing to think about is the type and number of lights per lighting circuit: they will determine the optimum module selection:

The dimmable light will need the evonHOME dimmer module L1424. Each module can control 2 lighting circuits. In addition to the dimmer modules, you will need a dimmer pack for each dimmable light suitable for your type of bulb, for example the Eltako SUD12 1-10 V universal dimmer switch. The evonHOME dimmer module L1424 controls the dimmer pack via 0-10V or 1-10V; you can switch your dimmer pack or an intermediate relay on or off via the digital output of the dimmer module. Two dimmer circuits can be connected to each module.

The other lights will either require the evonHOME lighting module L1244 with integrated 230V/16A relay or the evonHOME lighting module L1144 to connect external relays for larger loads. You can choose either, or ask your electrician to decide for you. Four lighting circuits can be connected to each module.
