REGULATOR REGISTRATION
5
Each room regulator should be registered in a zone. In order to register,
go to the external controller menu and select: (Menu > Fitter's menu
> Main module/Additional modules > Zones > Zone... > Room
sensor > Sensor selection > Wired RS) and press the registration
button on the regulator.
If the registration process has
been completed successfully, the
external controller screen will
display a message to confirm
whereas the room sensor screen
will display Scs. If the room
sensor displays Err, an error has
occurred during the registration
process.

NOTE
• Only one room regulator may be assigned to each zone.
• The regulator can serve as a floor sensor. In order to do this,
connect the NTC sensor to the regulator and activate it by double-
clicking the registration button. After successful activation, the Scs
message will appear on the controller display. The Err message
displayed on the screen of the room regulator indicates an error in
the activation process. The activated sensor must be registered in
the L-12, ML-12 or L-X WiFi external controller.(Menu > Fitter's
menu > Main module/Additional modules > Zones >
Zone... > Floor heating > Floor sensor > Sensor selection >
Additional sensor > ON).
PRE-SET TEMPERATURE
7
The pre-set zone temperature may be adjusted directly from the EU-R-12b
room regulator using the buttons < >.
During inactivity, the current zone temperature is displayed on the
controller screen. Use the buttons < > to change the set value. When
the pre-set temperature has been defined, the setting screen will appear.
Time settings can be changed using the buttons < >:
- for a specific number of hours - click the button < > until the desired
number of hours is displayed, e.g. 1h (the pre-set temperature will apply
for 1 hour, and then the previous setting will apply: schedule or constant
temperature Con). In order to confirm, press the Menu button ●.
- permanently - press the button > until Con is displayed (the pre-set
temperature will be valid for an indefinite period of time, regardless of the
schedule settings). In order to confirm, press the middle button ●.
- if you want the pre-set temperature resulting from the weekly schedule
settings to apply, press the button < until OFF appears on the screen. In
order to confirm, press the middle button●.
- return to the previous setting (schedule or constant temperature Con)
press the button < until 0 is displayed. Confirm by pressing the Menu
button ●.

INSTALLATION
2
In order to connect the floor sensor or wires, remove the rear cover of
the regulator.
4
The system uses a terminating connection. Depending on the order in
which the regulators are connected to the external controller (as the first
one or the one in the middle of the regulator's transmission line with
the external controller), set the terminating resistor in the regulator in
the appropriate position. ON turns the resistor on, and 1 is the neutral
position. Detailed information on the terminating connection of the
external controller with the regulators is described in the EU-L-12, EU-
ML-12 and EU-L-X WiFi manuals.

• Hold the registration button to display the current software version.
Remember the following rules:
- A registered regulator can be deleted (Menu > Fitter's menu > Main
module / additional module > Zones > Zone ... > Room sensor >
Sensor selection > Wired RS) or disabled using the external controller
(by deselecting ON in the sub-menu of a given zone).
- If the user attempts to assign a regulator to the zone to which other
regulator has already been assigned, the first regulator becomes
unregistered and it is replaced by the other one.
- If the user attempts to assign a sensor which has already been assigned
to a different zone, the sensor is unregistered from the first zone and
registered in the new one.
It is possible to set individual pre-set temperature value and weekly
schedule for each room regulator assigned to a given zone. The settings
may be configured both in the external controller menu and via www.
emodul.eu (use the module). The pre-set temperature may also be
adjusted directly from the room sensor using the buttons < >.
