Presented electric wiring plans were made with the help of Elwin software which is made by 3xM Automation company. New plans can be made with modification of included Elwin project or with modification of DXF plans with any DXF capable program. With the Elwin project, all HIQ symbols are included. The whole design plan can be also downloaded as a PDF file.

Single phase power input, connection of RCD switch (Residual Current Device) and power meter.
Input can be single or three phase.
The power meter on the wiring plan is connected to measure the whole electricity consumption, but can be connected to any device (or group of devices). Only single phase electricity measurement is available.

Suggested fuse plan.

24V power supply (PS) for control system, Home controller and CAD-232-A2-IQ.
24V power supply can be optionally used for LED lighting (up to 2.5A with serial power supply, larger power supply can be used).
Home controller (HC) is the heart of the system. It is connected to the network (ETH) and has optional inputs (connections are on page 15) and outputs (connections are on page 16).
CAD-232-A2-IQ expander is used as communication interface between home controller and power meter (If power meter is not used then the expander is not necessary). It is connected to a home controller through IEX bus, to COM2 on home controller input and to power meter (RS485 communication).

Light controllers (LC) are connected to IEX bus, we can connect up to up 4 LC to 1 home controller. On the top side are inputs and on the bottom side are outputs (connections are on page 17-24).

Up to 4 light dimmers can be connected to 1 HC. On sample plan we use 2 Light dimmers drivers for LUD-12 universal light dimmers.

Up to 2 Blinds controllers (BC) can be connected to 1 HC.

Bus extender (BE) is a passive switch for easy IEX bus interconnection between cabinet and field modules.

Up to 4 light dimmers can be connected to 1 HC. On sample plan we use 2 LED stripe dimmers.

Up to 4 Scene Controllers can be connected to 1 HC. On sample plan are 4 Scene Touch Panels, but also Scene Panels and Scene controllers can be connected in the same way.

Up to 5 Thermostats can be connected to 1 HC. On sample plan we use 5 Touch buttons electronic thermostats, but also ordinary Electronic thermostats and Blind electronic thermostats can be connected in a similar way.

Optionally we can connect window switch on each thermostat (sample on –TH02 and -TH03) (not possible with Blind electronic thermostat).

Up to 5 Fan-coil controllers (FC) can be connected to 1 HC. On our sample plan we have 3 FC, 2 thermostats are controlling radiator valves (page 36-38).

FC controllers are the last items on IEX bus. Longer IEX bus lines (over 100m) must be terminated with a 120ohm resistor between CANL and CANH (-R1).

Blank page for future extensions.

If used, optional lightness sensor must be connected to IW0 analog input on home controller.
All other inputs are left for custom programming solutions (10 digital inputs IX0-IX7, IX8A, IX9B and 3 8-bit analog inputs IW1-IW3).

QX0-QX4 outputs – can be used for radiator valves or to control other heating/cooling devices. Internal relay is used for valves, other loads are recommended to use an additional 16A installation relay.
In our plan we use 2 radiator valves (and 3 Fan-coil controllers).
QX5 output – is used for Air Conditioner.
QX6 output – is used for Boiler.
QX7 output – is used for Chiller.
All three outputs are connected to external installation relays (-K.A, -K.B and -K.C) .

Lights and managed power sockets are connected to Light controllers .
Several button combinations are possible.
Managed power sockets should be connected through installation relays (-K12-K14, -K22-K23 and -K30-K33).

A sample plan assumes use of managed and unmanaged sockets. Managed sockets are connected to Light controllers. External installation relays should be used on Light controller outputs.

On sample plan we use 2 Light dimmers drivers. On each driver we can connect up to 4 LUD-12 universal light dimmers.

On our sample plan we have 2 Blinds controllers (BC) with 9 blinds and 9 double-push buttons.

On sample plan we use 2 LED stripe dimmers. RGBW (red-green-blue-white) LED stripe is connected on the first dimmer and the second dimmer controls 2 white LED stripes (2 outputs are empty). 2 push buttons are connected on the second dimmer.
