Safety information!
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 radio repeater into the socket
2.)
Shortly press the learn key at the repeater
– the indicator lamp blinks red
3.)
Switch the radio transmitter 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 receiver 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 receiver 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 radio temperature sensors
(transmitters/sensor) and radio heating controllers (receivers/actuator) 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 radio heating controller used for controlling radiator valves (HTFMA-180.161).
3. Functioning
The MRCOA-014.201 receives and repeats exclusively information from radio temperature 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 transmitters and improves the reception conditions
for the associated receivers (avoidance of radio shadows). One MRCOA-014.201 repeater can act as a wireless node for as many as 16 radio
temperature 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 transmitters near the
floor will reduce the radio range.
4. Activation and putting into operation
Once plugged into the socket, the repeater is immediately ready for operation and the corresponding transmitters can be assigned (see section 6). The
data of all actually assigned (learned) transmitters remain stored even after a power failure. No repeated assigning/learning procedure needs thus to be
performed in the case of a repositioning or a power outage.
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 functions enables to assign the MRCOA-014.201 to the respective radio transmitters. The lean key can be accessed directly from the front of
the MRCOA-014.201.
6.1
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 transmitter 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
transmitters are being repeated. The red indicator lamp at the receiver
goes out once the range has been extended successfully. If intending to
extend the range by linking up repeaters, the corresponding transmitter
must be assigned to all linked up repeaters forming this line.
6.2
Position the repeater in a suitable place. Once the self-optimisation procedure has taken place, the correctly working radio connection between
the transmitter(s) and the repeater is indicated by a lamp at the repeater that lights green. This lamp is lit for approx. 1 hour after the last
assigning (learning) procedure (the lamp goes out after this time). If a radio link is interrupted within the first hour after the assigning (learning) of
a transmitter, the lamp at the repeater lights red after approx. 2 minutes. The existence of a correctly working radio connection can, 15 seconds
after the last assigning/learning procedure, be checked at any time by again triggering a learning procedure at the transmitter. If the lamp at the
repeater starts blinking green, the transmitter has been assigned (learned) correctly and a correctly working radio link exists. If a radio link loss
going over minimum 10 minutes occurs within the last 24 hours, this is indicated by an indicator lamp, which repeatedly (every 3 minutes) lights
green continuously for 3 seconds.
Shortly press the learn key at the transmitter. If pressing the learn key at the transmitter for more than 10 seconds, the device changes over to
cancelling mode (see section 7.).
