TAC Xenta® 102-VF
VAV Controller with Valve Reheat
TAC Xenta 102-VF is a zone controller for VAV heating and cooling applications that use fan on/off control and modulating valve
reheat.
The con trol ler keeps a constant temperature by controlling the air flow with the aid of a Belimo® VAV Compact; a valve reheat coil
is used for the hea t ing stage. Through a carbon dioxide sensor, the air quality can be controlled in the zone.
The controller is a LonMark compliant device that communicates on a LonTalk TP/FT-10 network via a twisted-pair, unpolarized
cable. It is able to operate both as a stand-alone unit and as part of a system. All network variables can be monitored and configured
via the TAC Xenta OP, if the OP version is 3.11 or higher.
STR 100 is a range of wall modules intended to be used together with TAC Xenta 102.
There are plug-in terminal blocks available for the TAC Xenta 100 series that can be attached to the existing terminals.
