Communication with other controllers

Communication with other controllers
Tracer AH540/541 controllers operates either in stand-alone mode or as
part of a building automation system. In either mode of operation, multi-
ple controllers can be bound (bindings are configured using the Rover ser-
vice tool) to other LonTalk
®
-based controllers so they can communicate
data to one another. Controllers that are bound as peers can share the fol-
lowing data:
• Setpoint
• Zone temperature
• Zone relative humidity
• Outdoor air temperature
• Occupancy mode
• Heating/cooling mode
• Fan status
• Unit capacity control
Applications having more than one unit serving a single space can benefit
by using this feature; it allows multiple units to share a single space tem-
perature sensor and prevents multiple units from simultaneously heating
and cooling. For more information, see “AH540/541 network variables” on
page 109.
