Safety instructions
WARNING
Follow carefully these safety and installation instructions. Improper work may lead to serious harmful for your health and also may damage seriously the interface
and/or the Hydro unit.
• This interface must be installed by accredited technical personnel (electrician, installer, or technical personnel) and following all the safety instructions.
• Before manipulating the Hydro unit, be sure it is completely disconnected from Mains power.
• Do not modify the unit. (A fire or an electric shock may occur)
• This interface must only be installed in a restricted access location by user.
• Do not install the unit in any of the following places.
• Humid or wet place
• Dusty place
• Place exposed to direct sunlight
• Place where there is a TV set or radio within one meter
• Place exposed to rain (outdoors, under eaves, etc.)
• Use predefined cable and connect them certainly. Keep the connecting terminal free from external force.
It may cause an exothermic or a fire.
• Strip the insulation from the cable that connects to the connector (RS-485 and A B bus) following the dimensions shown in the diagram below.
• When connecting the cable to the connector (RS-485 and A B bus), ensure the core wires do not protrude from the connector.
• Use two-core cabtyre cable.
Installation instructions
• Disconnect the Hydro unit from Mains Power.
• Fix the interface beside the Hydro unit (wall mounting) following the instructions in the diagram below or install it inside the Hydro unit (respect the safety
instructions given above).
• Connect the interface to A B bus in any point of the bus. The A B bus is the bus that connects the Hydro unit and the wired remote controller, is a two-wire bus
connecting terminals A B of both, this A B connection has no specific polarity.
• Connect the RS-485 bus to the connector RS-485 of the interface.
• Close the Hydro unit and reconnect it to Mains Power.
• Follow the instructions on the user manual for configuring and commissioning the interface.
• Follow the instructions of the next page to configure the interface through on-board DIP-switches.
IMPORTANT:
•Use only one remote controller. A sub-remote controller cannot be connected when connecting this interface.
• It is not possible to mix and connect Hydro unit 4 series and 5 series.
NOTE
The cable used for connection of BMS-IFMB0AWR-E to A B bus can be any two-core cabtyre cable, the maximum distance for bus A B is 50 meters, consult the
manual of the Hydro unit for more details.
Respect the maximum distance of 500 meters for the bus, no loop or star topologies are allowed for RS-485 bus, a terminator resistor of 120 Ωmust be present at
each end of the bus to avoid signal reflections and also a fail-safe biasing mechanism.
NOTE
In its place there is a pair of cables to connect the Remote Controller. Use these cables to connect the AB bus. Check your Hydro unit user or service manual for
more information.

* Default value
S4 - Degrees/Decidegrees (x10), temperature magnitude (ºC) and RS-485 termination resistor
* Only in the interfaces conected at both ends of the bus must be activated the termination resistor, not in the rest. The RS-485 bus can be biased through internal
jumpers JP2 and JP3. Consult the user manual for details.
