Configuration: BMS Interface card BACnet TCP/IP Ethernet
1.
Go to BMS configuration (will time out after 5 minutes if no buttons pressed)
Change the settings for BMS configuration from the display menu as mentioned
below.
Address: No change required (address is irrelevant for this card).
Protocol: CAREL
Speed: 19200 (this value is set from factory to communicate between heat pump and
BMS card)
2.
Open the heat pump enclosure and check the BMS card.
The BACnet TCP/IP Ethernet card features a button (PUSHBUTTON) and two
indicator lights (STATUS LED and NETWORK LED).
Functions of the button: When starting up the TCP/IP Ethernet card, this is used to
select, for network communication, whether to use the factory parameters or the user
parameters. In normal operation, reboots TCP/IP Ethernet card without needing to
disconnect the power supply.
Status LED: indicates the status of communication with the heat pump and the card.
Once the starting sequence has been completed, the Status LED flashes to indicate
the quality of communication.
a.
If Status LED flashes green or green steady, then communication with the
BACnet TCP/IP Ethernet card is OK.
b.
If LED is red or green-red-green, then the communication is not established.
In that case, check the BMS configuration.
Network LED: Displays the status of the physical network connection (Ethernet
connection signals), regardless of whether the network parameters are correct;
usually this must be green and flash when data is transmitted/received.
3.
