Edit the U_BMS.txt file, on the controller microSD card, to setup
the controller Modbus RTU interface.
Available settings (default in bold):
•
BMS Slave address: 1 to 247
•
BMS Baud rate: 19200 or 9600
•
BMS Parity: even, odd, no (or none)
•
Heat pump integration via BMS: off or on
on = enables dynamic heat curve offset in integrated heat
pump, and integrated heat pump defrost state.
•
Exclude zone from heat curve offset calculation:
0, or 1 through 12 (0 = no channel)
Select master channels of the zones (lowest numbered
channel in the zone) to exclude.
The zone subchannels follow the state of the master
channel.
Example: 3,5,12 = exludes channels with master channels
3, 5 and 12.
•
Bypass zone: 0, or 1 to 12 (0 = no channel, example: 3,12)
Select master channels of the zones (lowest numbered
channel in the zone) to bypass, MAXIMUM 2 channels.
The zone subchannels follow the state of the master
channel.
Example: 4,12 = bypasses zones with master channels 4
and 12.
•
Ceiling cooling channel: 0, or 1 to 12 (0 = no channel,
example: 1,4,10)
Select the channels which controls ceiling cooling in the
zones. The zone subchannels will not follow the state of the
master channel.
Example: 1,4,10 = set ceiling cooling to channels 1, 4 and
10.
•
BMS Temperature format: c or f
c = Celsius, f = Fahrenheit
Repeat for each Base PRO controller in the system.
