BMS interface from A.O. Smith
A.O. Smith has launched a BMS interface for the BFC, SGE and SGS appliances.
By using the BMS interface you can extract data from the appliance. This data can be converted to your building management software which enables you to monitor the hot water installation.
The BMS interface converts the information of the installation to a ModBus protocol, one of the most used protocols in building management.
The BMS interface can monitor almost 50 parameters; Legionella settings, fault indications, the contribution of the solar system, temperatures in the appliance, burning hours, etc. The complete list of parameters can be found in the instruction manual on the website.
Monitoring the Legionella settings and checking the programme is very important. The BMS interface can register, by processing the information regarding the temperature in the tank, that the Legionella programme ran at a specific time and date.
