Navien Smart Plus uses 2-way communication on an 868 MHz radio frequency (RF)
band to control the heating system. The wireless communication module (BCM-40RW)
operates as the control centre of the system, and the Navien boilers (LCB700 or NCB-CE)
support 2-wire communication (KIW) technology. It is possible to control it using a
2-wire connection from the BCM-40RW terminals.
Navien Smart Plus consists of the wireless thermostat (NRC-10R) and wireless
communication module (BCM-40RW). The devices are already paired (completed
RF pairing procedure). Therefore, when installing them, no additional initial pairing
procedure is needed to use the devices.
Navien Smart Plus can be installed in combi/system and regular boilers. With an
additional wireless thermostat (NRC-10R) and an additional wireless wiring centre (VCU-
10R), multizone control can be implemented in a combi boiler environment via the S/S+
Plan and in a system/regular boiler environment with the S/S+/Y/W Plan.
Charge for App service is subject to be imposed after prior notice in accordance with the
policy of the manufacturer.

Connecting the KIW
communication cable
The KIW communication cable from
the boiler must be connected to the
wireless communication module.
Do not supply 230 VAC to the
wireless communication module.
Doing so may result in fire, severe
personal injury, or death.
Installing the wireless communication module
Connect the KIW communication
cable from the boiler to the wireless
communication module and install it
on a wall near the boiler as the boiler
provides power for the communication
module.
Also, for the best RF system performance,
install the wireless communication
module in an open area so that it can
pair with the wiring centre and wireless
thermostats.
• Do not install the wireless
communication module near
heat sources, such as radiators,
chimney walls, televisions, and
direct sunlight. Doing so may
damage the device.
• Install the wireless
communication module at least
30 cm from any metal objects,
including wall boxes, and at least
1 m from any other electrical
equipment, such as radios,
televisions, and PCs. Metal
objects and electrical equipment
may affect the RF communication
between RF devices.

Connect one end of the extension cable to the port on the front panel of the boiler
and the end of the extension cable to one end of the KIW communication cable from
the wireless communication module.
<For NCB-CE boilers>
<For LCB700 boilers>
Set the DIP switches for NCB-CE and LCB700 boilers as follows.
• NCB-CE Panel DIP SW: 4-OFF, 5-OFF
• LCB700 Boiler DIP SW2: 6-OFF, 7-ON, 8-OFF

When pairing the wireless
communication module with the RF
receivers, such as the wiring centre or
wireless thermostat, the devices should
be in pairing mode. Refer to the Wireless
thermostat or Wiring centre Installation
& Operation manual for information on
entering pairing mode.
