TAC Xenta 121-FC is an easily programmable controller intended for both 2-pipe and 4-pipe applications, with or without re-heat . It can be configured for use with a multitude of valve actuator types, such as on/off, multistage, increase/decrease, PWM, and so on . The controller has different types of fan control and advanced fan control functions, including on/off delays, boosting, and conditioning.
The sequences for cooling, heating, and fan are completely user-programmable, allowing for numerous applications . For energy savings the controller has built-in economizer functionality . Use TAC Xenta 121-FC with any TAC STR (1 .8 kohm) room unit .
Set-up is done using the programming tool TAC ZBuilder, which can be run stand-alone or as a device plug-in to either TAC Vista® or an LNS-based tool . Using Vista or an LNS-based tool, the configuration settings are downloaded into a TAC Xenta 121, prepared with the necessary basic application software.
The controller is a LonMark® compliant device aimed at communicating on a LonTalk® TP/FT-10 channel . It is able to operate both as a stand-alone device and as part of a system . In- and output net work variables can be monitored via the TAC Xenta OP, but programming relies on the use of the TAC ZBuilder
