Issue:
This document describes the operation of the Uniflair BACnet (Building Automation and Control Networks).
Product line:
Uniflair
Environment:
All Models and Serial Numbers
Cause:
Install
Resolution:
All the units must be fitted with a RS485 card, trough that they are connected to the RS485 serial cable. On one side there will be the 120 ohm resistor, on the other, the gateway which will translate the variables from Uniflair language, to LON language.
To realize a local net to be connected to a BMS with protocol BACnet, it’s necessary:
• gateway LBM every 8 units; (not necessary with pCOnet - pCOWeb)
• 1 RS485 serial card for every controller;
• 120Ω resistor;
• PC for the gateway configuration
BACnet is a supervisory system created from AHRAE:
“American society of Heating, refrigerating and Air conditioning Engineers”
These are the ways how the information under BACnet can be sent to Uniflair controllers:
BACnet IP/Ethernet
pCOnet: RS485
Gateway
Carel :
- Protocol Carel
- Connection RS485 or RS422
- Max 8 units
- No software modification needed
BACnet :
- BACnet PTP
- Connection RS232
