Use
The RCR114.1 works as a router-eligible end device (REED) in the network created by
RDS110.R.
Functions
RCR114.1 can be configured via the DIP switch on its backside to be a relay box or wireless
repeater.
Relay box
RCR114.1 is installed within the network coverage of RDS110.R.
Wireless repeater

If RCR114.1 is installed too far away from RDS110.R, another RCR114.1 (works as a
wireless repeater) should be added in between to extend the network coverage. See
Mounting [➙ 4] for details.
Note:
1. DIP switch 2 is reserved for internal use only.
2. One RDS110.R can pair up with at most 3 repeaters and 6 relays to extend the network
coverage.
3. You cannot mannually turn ON / OFF a RCR114.1.
Mechanical design
The RCR114.1 consists of 2 parts:
●Plastic housing which accommodates the electronics
●Mounting plate
Operation and settings
1 LED for indication of operating status
2 Button for user operation

Notes
Security
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
Mounting
●The device is suitable for wall mounting and surface mounting.
●Enclose the conductors in a conduit when surface mounting.
●Reserve sufficient free space for ventilation (refer to the following picture).
●Avoid direct solar radiation.
●Adhere to allowed ambient conditions.
●Install the receiver close to RDS110.R if possible. The communication range in a building
is typically 60 m without any blockades. Please note that the range can vary as walls,
floors, wireless interference and other factors may reduce the signal strength.

●Choose the location to ensure largely interference-free reception. When mounting the
receiver, observe the following:
– Do not mount in a control panel
– Do not mount on metallic surfaces
– Do not mount near 2.4 GHz wireless electronic devices such as PCs, WiFi routers,
microwaves, etc.
– Do not mount near constructional elements with fine metal or large metallic
structures such as a distribution box
Wiring
●The AC 230 V mains supply line must have an external circuit breaker with a rated
current of no more than 10 A.
●Ensure that wiring, protection and earthing comply with local regulations.
●Adapt the line diameters as per local regulations to the rated value of the installed
overcurrent protection device.
●Disconnect from power supply before removing the unit from its mounting plate.
●Make sure the receiver is not connected to power during wiring.
