TAC Xenta
Zone Controllers
TAC Xenta zone controllers are individual room controllers based on
L
ON
W
ORKS
®
for controlling and optimizing secondary heating/cooling
systems. The TAC Xenta zone controllers are specifically designed for zone
applications and include hardware and software. The controllers can be
adapted to individual requirements using the flexible configuration set-
tings. Parameters can be set on site using the TAC Xenta Operator Panel or
centrally using the TAC Vista central system. Room sensors with setpoint
adjuster make on demand adjustments possible. Unlike traditional zone con-
trollers, intelligent L
ON
W
ORKS
®
based devices can also be controlled directly
via the bus.
The individual room controllers are integral components in a building’s auto-
mation system and communicate via the L
ON
W
ORKS
®
bus with the TAC Xenta
controllers and the TAC Vista central system. Dynamic data exchange allows
on demand optimization of the primary systems while maintaining comfort-
able conditions. To ensure optimal functionality, individual room controllers
and/or parameters can be organized into groups so that several controllers
can be set simultaneously. Groups also allow statistical evaluations and can
therefore optimize the whole system. All TAC Xenta individual room control-
lers are LonMark
®
certified and allow completely open communication with
other systems within a L
ON
W
ORKS
®
network.
