Installing The Wireless Communication Module; Connecting The Kiw Communication Cable - Navien BCM-40RW Installation & Operation Manual

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.
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.
