The ED-RU-… room unit is connected to the controller by using a Regin
EDSP-K3 cable, as shown in the following wiring diagram.

Configuration and commissioning
It is recommended that Application tool is used to perform configuration
and commissioning. A room unit with display can also be used by
modifying the parameters that are accessed via the parameter menu in
the display. The display parameters are listed in the manual.
Two-room installation
In a two-room installation, it is important to pay attention to how the
controller identifies the connected room units for room 1 and room 2.
Follow these steps to ensure that the controller automatically associates
each connected room unit with room 1 and room 2 in a correct way:
1. Make sure that the two room units have different ELA addresses.
The ELA address has the format 1:[1-30] and is printed on a label
that is located on the back of the room unit PCB, as shown in the
following figure.
2. In Application tool, connect to the controller and enable the two
rooms function.
The configuration setting for enabling the two rooms function is
located in the
Configuration -> Control functions
pane in Application
tool.
3. In room 1, connect one of the two room units to the controller.
Before moving on to step 4, allow the controller to identify the room
unit. It takes up to 30 seconds for the controller to identify the room
unit.
For room units without display, the LED in the centre of the room
unit blinks red and blue during the identification phase. The
controller has completed the identification when the LED does not
blink red and blue anymore.
For room units with display,
FAIL
or
is shown in the display
during the identification phase. The controller has completed the
identification when neither
FAIL
nor
is shown anymore.
4. In room 2, connect the other room unit to the controller.
Allow the controller to identify the room unit. It takes up to 30
seconds for the controller to identify the room unit.
