Application information
84
The controller’s default setpoints are:
■
Unoccupied cooling
■
Occupied standby cooling
■
Occupied cooling
■
Occupied heating
■
Occupied standby heating
■
Unoccupied heating
The controller uses the appropriate setpoint based on the controller’s
occupancy and heating/cooling modes.
A configuration parameter exists in the controller to enable or disable the local
setpoint input. Use Rover service tool to modify this and all other unit
configuration items.
Stand-alone peer-to-peer
Tracer ZN.520 zone controller allows peer-to-peer (also referred to as master/
slave) data communication. Data such as space temperature, setpoint, and
occupancy can be shared from a master control to a peer control with or
without the presence of Tracer Summit. This communication allows all units to
operate with the same data to prevent conflicts between units. See Figure 6.
Figure 6
Simple data sharing application
In Figure 7 on 85, multiple masters and slave controllers are connected on the
same Comm5 communication link with Tracer Summit. The master for Zone A
is the only controller with a zone sensor. Master A communicates data to slave
controllers A1 and A2. Connected to the same communication link, the master
controller for Zone B is connected to the zone sensor and communicates data to
slave B1.
