Zone Management

You can associate an RTU application with a zone.
Zone is a group of RTUs and/or AHU (air handling unit)
applications that shares the same heating, cooling,
dehumidification setpoints, and other control parameters.
The primary purpose of zone control is to maintain a
specific temperature and humidity level throughout a wide
area using multiple rooftop units.
When an RTU application is associated with a zone,
some inputs of RTU application should use the output
values from zone. These are the property mapping list:
RTU Inputs
ZONE OCC
ZONE TEMP
ECONMIZE
DEHUMDIFY
OCC HEAT
UNOCC HEAT
OCC COOL
UNOCC COOL
OCC DEHUM

periodically with a 10-second interval.

Hand-Held Terminal Support

1. You can connect to the RTU board with a hand-
held terminal (HHT) to read or write the
configuration of this RTU board.
2. When a HHT is connected to a RTU board, any
setpoint change made from UI will not be sent to
the RTU board. Some controllers will accept the
changes but some will not.
3. The Site Supervisor downloads all setpoints and
configuration parameters you changed from UI
upon receipt of a message from the RTU that the
hand-held terminal is disconnected. This will
overwrite any changes made using the HHT.
4. The Site Supervisor does not accept permanent
changes made via the hand-held terminal to the
Site Supervisor.
