Entrust a qualified local technician to perform installation. Do not try to install the unit
by yourself.
Before cleaning or maintenance, ensure the power supply is cut off. Do not use water
for washing to prevent electric shocks.
Do not operate with wet hands to avoid electric shocks.
Do not use pesticides, disinfectants, or flammable directly on the controller as they
may damage the device or cause fires.
When the IDUs are powered separately and the number of IDUs to be connected is
more than 10 or the communication distance is larger than 200, repeaters are
required.

Repeater
REPE-01
Product Overview
A repeater is a connector working on the physical layer, with the following features:
●Signal repeater: re-transmits or forwards data signals to extend the network
transmission distance.
●Power supply repeater: compensates the voltage drop caused by communication
wire resistance to increase the bus voltage.

Installation Instructions
Warning
Precautions
●To ensure correct installation, read the "Installation Instructions" section of this manual.
●All the warnings provided here are important for safety and must be followed.
●Entrust the local distributor or local service agent to appoint a qualified technician to
perform the installation. Do not try to install the unit by yourself.
●Do not connect the communication wire when the power is on. Otherwise, the circuit
board will be damaged.
●Do not connect the power cable (high voltage) to the communication (low voltage)
terminal. Otherwise, the circuit board will be damaged.
●Do not connect M1M2 with the PQ of IDU. Otherwise, the circuit board will be
damaged.
●Note the distinction between the communication port of the upstream IDU and that of
the downstream IDU. Be careful not to make them confused. Otherwise,
communication failure will occur.
●Use the specified cables as the communication wires.The wires should be fixed with
clamps to avoid stress on the terminal block.
●Do not install the repeater in any corrosive, flammable or explosive environment or
place with oil mist (such as a kitchen).
●Do not install the repeater outdoor or in a wet place and avoid direct sunlight.
●Do not knock, throw, or disassemble the wired controller.
●Please install the repeater after painting the wall to prevent water, lime and sand
from entering the repeater.
●When installing the equipment, all requirements of the mentioned standard must be
fulfilled. And when necessary, suitable enclosure and type of supply connection
should be provided by end system.

Repeater Installation
Ⅰ. Push the cover hard on the screwdriver icon till snap fasteners of the
cover seperate from the base, then open the cover. Install the power cables
and communications wires properly according to the wiring diagram.
Make sure the power is off when operating.
Do not raise the upper cover with excessive force to avoid damage to the
cover or the circuit board.
Warning
Snap fastener

Ⅱ. Fix the repeater base on the wall or a proper location with a screwdriver.
Four positions need to be fixed with screws.
07
Ⅲ. Finally, close the upper cover and the bottom cap of the repeater and
tighten them with two fixing screws.

●The power supply of the repeater cannot be cut off separately. It needs to be always
powered on or switched on and off with the ODU power supply.
●Use round-type terminals with correct specifications to connect the power cable. The
power cables must be a 2×1.0mm copper core cable.

Do not connect M1M2 with the IDU's PQ, D1D2 or X1X2 or any other different
communication network. Otherwise, the circuit board will be damaged.
If the total communication distance between IDU and ODU exceeds 200m or more
than 10 IDUs are configured, use a repeater to increase the bus voltage.
A maximum of 2 repeaters can be installed in the same refrigerant system.
Use 2×1.5mm PVC sheathed flexible cords in compliance with AS NZS 3000
Electrical installations (known as the Australian New Zealand Wiring Rules) and AS
NZS 3008 Electrical Installations (DC resistance ≤ 1.33Ω/100m) as communication
cables.
Note the distinction between the communication port of the upstream IDU and that
of the downstream IDU. Be careful not to make them confused. Otherwise,
communication failure will occur.
Connect the port of TO UP IDU with the upstream IDU. The upstream IDU is
located in front of the repeater and near the ODU.
Connect the port of TO DOWN IDU with the downstream IDU. The downstream IDU
is located behind the repeater and away from the ODU.

First wiring method: The communication wire should pass through the wire clamp on the
right side of the repeater. The communication wire of the upstream IDU should be
connected with CN3 (TO UP IDU) terminal block(M1 M2) while the communication wire of
the downstream IDU connected with CN2 (TO DOWN IDU) terminal block(M1 M2). The
wires should be fixed with clamps to avoid stress on the terminal block.

Warning
If the total communication distance does not exceed 200m and no more than 10 IDUs
are configured, the units are powered by the master ODU and no repeaters are required.
If the total communication distance exceeds 200m or more than 10 IDUs are configured,
repeaters are required.
The repeaters shall have the same load capacity as the ODUs, connecting with up to
10 IDUs, with a communication distance of no greater than 200m.
A maximum of two repeaters can be installed in the same refrigerant system.
A maximum of 30 IDUs can be installed in the same refrigerant system by using
repeaters.
