TAC Xenta

Zone Controllers

TAC Xenta zone controllers are individual room controllers based on

onWorks

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 LonWorks

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 LonWorks

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 LonWorks

network.
