Application information
Setpoint operation
Controllers sharing information peer-to-peer, also referred to as
master/slave
,
can share a variety of data, including the heating/cooling setpoint
(communicated from a master to a slave).
Each controller derives its effective setpoint and default setpoints (including
deadbands between setpoints) from the setpoint input (hardwired or
communicated). To make sure the peer-to-peer setpoint application results
in identical setpoints for each communicating controller, each controller must
have exactly the same default setpoints.
The standalone master controller derives its setpoint from either the local
hardwired setpoint input (if present) or from its default setpoints. Peer-to-peer
applications often require the use of one hardwired setpoint to be shared
across two or more controllers. You can achieve this by wiring the adjustable
setpoint (typically included as a part of the Trane zone sensor module) to one
controller—defined as the master. Next, use Rover™ to set up the master and
one or more slaves to share that setpoint. For this application, each
communicating controller uses the same setpoint.
