Waterproong: The product is not waterproof. Make sure that it is
always dry. Moisture will corrode the electronic components inside
and may result in short circuit, faults and risk of electric shock.
Cleaning: Clean the product with a dry cloth. Do not use chemicals,
solvents or potent cleaning agents.
Environment: Do not expose the product to extreme heat or cold,
as this may damage the electronic circuits or shorten their service
life.

CONFIRMATION OF DELETION OF ALL MEMORY SLOTS
The relay in the MCMR-2000 clicks 4 times and any lights
connected ash 2 times.
MEMORY
The MCMR-2000 has 32 memory slots and can be controlled from
up to 32 dierent units (remote controls, motion detectors, magnetic
switches, Bridge, etc.). If all memory slots are lled, the oldest slot
will be deleted when a new channel is programmed.
CONTROL
The receiver can be controlled in several ways.
1. With a programmed System Nexa Remote Control
2. With other programmed System Nexa transmitters
3. With a Nexa Smart Hub
4. With Nexa Bridge
SAFETY AND INFORMATION
Range indoors: up to 30 m (optimal conditions). The range is
heavily dependent on local conditions – such as if there are any
metals nearby. For example, the heavy metal coating in low-
emission energy glass has a negative impact on the range of the
radio signals. There may be limitations on the use of the unit outside
the EU. If appropriate, check that the unit complies with the local
regulations.
Max. load: Never connect lights or equipment that exceeds the
maximum load of the receiver. This can result in faults, short circuit
or re.
Life support equipment : Never use Nexa products for life support
equipment or other devices where faults or disruptions can have
life-threatening consequences.
Disruptions: All wireless units can be aected by disruptions that
may have an impact on performance and range. The minimum
distance between two receivers should therefore be at least 50 cm.
Repairs: Do not attempt to repair the product. It does not contain
any serviceable parts.
ENGLISH
Built-in receiver for wireless control of lights, etc. The receiver
needs both a phase and a neutral connection. The receiver is fully
compatible with other System Nexa products.
SAFETY
Read all the instructions carefully rst. Call in a professional if
necessary. Nexa cannot be held liable if the product is used for
any purpose other than that for which it was designed, or if the
associated instructions are not followed.
Never connect lights or any equipment that exceeds the maximum
stated load of the receiver, as this can result in faults, short circuit or
re. Do not attempt to repair the product.
The product contains no serviceable parts.
INSTALLATION
Make sure that the wires are free from voltage by disconnecting
the current in the electricity panel.
Connect the phase (Live) to L, Neutral to N and the outgoing power
line (load) to L(arrow), see the circuit diagram.
PROGRAMMING
In order to operate the MCMR-2000 with a System Nexa remote
control (or other unit), the transmitter and receiver must be
connected as follows:
1. Connect voltage to the MCMR-2000
2. Briey press the “programming” button, the LED indicator will
start to ash slowly.
3. Press the “ON” button for the selected channel on a System
Nexa remote control within 12 seconds.
To program other System Nexa units (Motion detector, Magnetic
switch, Bridge, etc.) see the instructions for use for the respective
products.
CONFIRMATION OF PROGRAMMING
The relay in the MCMR-2000 clicks 4 times and any lights
connected ash 2 times.
DELETE MEMORY SLOT
1. Connect voltage to the MCMR-2000
2. Briey press the “programming” button, the LED indicator will
start to ash slowly.
3. Press the “OFF” button for the selected channel to be deleted
from a System Nexa remote control within 12 seconds.
To delete programming from other System Nexa units (Motion
detector, Magnetic switch, Bridge, etc.) see the instructions for use
for the respective product.
