Metasys

Metasys® (Johnson Controls) is a building automation system conceived by Johnson Controls.

The Airedale controllers are able to communicate directly using the RS485 serial card. The RS485 serial card is a small PCB (60mm x 30mm), which can be plugged into the controller to provide it with communication to the Metasys® system.

Once the RS485 serial card is fitted, a simple menu structure via the controller keypad, allows the operator to set the communication speed for the RS485 serial card and set the protocol to CAREL. The integration of the controller into the Johnson Metasys® system has been carried out repeatedly by:-

Johnson Controls
Via Monfalcone, 15
20132 Milan, ITALY
phone ++39 02 28042.1
fax ++39 02 28042.221

Documentation for the integration is provided by Johnson Controls in this instance as the set-up of the protocol change is carried out at the Metasys® BMS. A list of the variables is then provided to the system integrator who will then be able to connect to the Metasys® system with the support of Johnson Controls.
