Safety information! GB
The existing safety regulations are to be observed. The company charged with the installation of the device must, after the completion of the installation work,
instruct the user of the control system into its functions and in how to operate it correctly. These operating instructions must be kept at a place that can be
accessed freely by the operating and/or servicing personnel in charge.
Caution: Never open the device under any circumstances.
Caution: Operating the device in the vicinity of other devices that do not comply with the EMC directives may affect its functions.
The device must not be disposed of together with other household waste.

1. Short instruction
1.) Put the repeater into the socket
2.) Shortly press the learn key at the repeater –the indicator lamp blinks red (approach if link loss in b@home-system see section 6.2)
3.) Switch the sensor into the learning mode until the lamp on the repeater flashes green
4.) Install the repeater in a suitable place
5.) Check both at the repeater and the actuator if the radio link has been established correctly. (The indicator lamp at the repeater lights green for
approx. 1 hour. After that the lamp goes out and the red indicator lamp at the actuator goes out as well).
2. Application
The MRCOA-014.201 is a fully packaged radio repeater that enables to extend the radio working range between the sensors (transmitters/ radio temperature
sensors) and actuator (receivers/ radio heating controllers) used within an ALRE radio system. Furthermore, the device can be used for increasing the range of
the sensors / actuators in conjunction with the b@home gate. The integrated recessed socket is permanently operational and has been dimensioned for a max.
load of 230V/16A.
Caution: The b@home control unit (FTRCUd-210.021) cannot be assigned to this device. Furthermore, the device is not suitable for the direct extension
of the range of telegrams to the actuator used for controlling radiator valves (HTFMA-180.161).
3. Functioning
The MRCOA-014.201 receives and repeats exclusively information from sensors that have been assigned to it as specified in below section 6. Once positioned
accordingly, the MRCOA-014.201 extends the radio range of the learned sensors and improves the reception conditions for the associated actuators (avoidance
of radio shadows). One MRCOA-014.201 repeater can act as a wireless node for as many as 16 sensors of any assigned type. Up to three repeaters can be
linked up to form one line. The operating range of the radio link depends to a great extent on the spatial conditions prevailing on site. Usually, reinforced walls,
ceilings, metal housings or the installation of sensors near the floor will reduce the radio range. Information on the optimal positioning of the repeater in the alre
radio system / b@home system can be found at www.alre.de
4. Activation and putting into operation
Once plugged into the socket, the repeater is immediately ready for operation and the corresponding sensors can be assigned (see section 6). The assigned
(learned) sensors / rooms remain stored even after an interruption of the power supply. A repositioning or a power failure does thus not require performing any
further assigning/learning procedure.
5. Installation / removal
Even non-experts can activate the MRCOA-014.201 without any tools simply by plugging it into a 230V socket or deactivate it by removing it from the socket, as
the device requires no special installation. Opening the device is prohibited, as this could lead to serious personal injury be fatal due to the touching of mains
voltage carrying parts or components.
6. Assigning (learn) function / establishing of a radio connection
The learn function assigns the repeater to the sensor or room. The learn key is directly accessible on the front of the repeater.
6.1 Learning procedure in a not remote controlled control system
(direct connection of sensors and actuators without b@home-Gate)
A link loss is indicated by a red lamp at the actuator.
Shortly press the learn key at the repeater the indicator lamp at the repeater blinks red
for approx. 20 seconds. Press, within this time, the learn key at the sensor and keep it
depressed until the indicator lamp at the repeater changes from blinking red to blinking
green. The radio connection is now established and all telegrams of the learned sensors
are being repeated. The red indicator lamp at the actuator goes out once the range has
been extended successfully. If intending to extend the range by linking up repeaters, the
corresponding sensor must be assigned to all linked up repeaters forming this line.
6.2 Learning procedure in a b@home system
Depending on the type of link loss, different procedures are required. A loss of the link between a sensor and the b@home-Gate is indicated in the
b@home-App with a symbol at the concerned room and at the b@home-Gate with the "radio" lamp (lights yellow) and at the actuator with a red lamp. A
link loss between the b@home-Gate and an actuator is only indicated with a red lamp at the actuator.
6.2.1 Link loss between sensor and b@home-Gate
Press the learn key at the repeater shortly the lamp at the repeater blinks red for approx. 20 seconds. Press, during this time, the learn key at the
sensor and keep it depressed until the lamp at the repeater changes from blinking red to blinking green. The radio link is now established and all
telegrams of the leaned sensor are being repeated. Once the range has been enhanced successfully, the yellow "radio" lamp at the b@home-Gate goes
out and no radio loss is now being indicated in the App at the corresponding room any more. If intending to enhance the range by linking up several
repeaters, the corresponding sensor must be learned/assigned to all repeaters forming this linkage.
6.2.2 Link loss between b@home-Gate and actuator
Select in the b@home-App the room assigned to the actuator and select, likewise, in the menu "devices" the function "learning actuator". Press the learn
key at the repeater shortly the lamp at the repeater blinks red for approx. 20 seconds. Confirm, within this time, the message "actuator has been
prepared" in the b@home-App. The lamp at the repeater changes from blinking red to blinking green. The radio link is now established and all telegrams
of the learned/assigned room are being repeated. The red lamp at the actuator goes out if the radio range has been enhanced successfully. If intending to
enhance the range by linking up several repeaters, the corresponding room must be learned/assigned to all repeaters forming this linkage.
