TAC Xenta 401 Freely Programmable HVAC Controller

LonMark-networked plant controller with full HVAC functionality for building automation systems

Overview

The TAC Xenta 401 is a freely programmable controller from a family of communication-capable devices designed for heating and air handling systems. It holds full HVAC functionality including control loops, curves, time control, and alarm handling. The controller itself has no physical inputs or outputs — instead, it connects to required I/O modules from the TAC Xenta 400 series, supporting up to 10-15 modules depending on version. Programmed using the graphical TAC Menta tool, multiple Xenta 401 units can form a network to exchange data, and the controller can connect to a central TAC Vista Building Management System directly or via modem, with optional TAC Xenta OP operator panel support for local interaction.

Key Features

  • Full HVAC functionality: Handles control loops, curves, time scheduling, and alarm handling for heating and air handling systems.
  • Modular I/O expansion: Connects to TAC Xenta 400 series I/O modules (up to 10-15 depending on version) since the controller itself has no built-in I/O.
  • LonMark network communication: Communicates via LonTalk TP/FT-10 network, enabling multi-controller networks that share data.
  • Central BMS connectivity: Connects to a TAC Vista Building Management System directly or via modem for centralized monitoring and control.
  • Graphical programming tool: Configured using TAC Menta, simplifying commissioning and application development.
  • Hot-swappable design: Can be removed and reinserted from its terminal base without disconnecting the power supply.
  • Real-time clock with backup: Maintains accurate timekeeping (±12 minutes/year at 25°C) with 72-hour power outage protection.
