TAC-Xenta-700 — Schneider TAC Xenta VAV HVAC Controller
The Schneider Electric TAC Xenta 700 is a standalone, freely programmable BACnet/IP and BACnet MS/TP direct digital controller (DDC) designed for variable air volume (VAV) terminal unit control, AHU sequence control, fan coil unit (FCU) management, and general-purpose HVAC zone control in commercial buildings. The Xenta 700's 32-bit processor runs a fully programmable HVAC application logic with BACnet/IP native communication, enabling integration into any major BMS platform — including Schneider's EcoStruxure Building Operation, Johnson Controls Metasys, Honeywell WEBS, and Siemens Desigo — without protocol translation gateways. The controller accepts 6 universal inputs (configurable as 0–10 V, 4–20 mA, or resistance) and 4 digital outputs, covering all the sensor and actuator connections needed for a single-zone HVAC terminal application.
Xenta 700's VAV application templates pre-configure the controller for the most common VAV terminal sequences — cooling only, heating and cooling, with or without reheat, pressure independent or pressure dependent — reducing commissioning time from hours to minutes for experienced HVAC controls technicians. The built-in BACnet MS/TP port enables daisy-chain network connection of multiple Xenta 700 controllers to a single Xenta 511 or 527 IP router, reducing IP network infrastructure costs in large multi-zone commercial building HVAC control systems. The controller's plastic DIN rail enclosure and spring-clamp terminals allow installation within VAV terminal unit cabinetry without requiring a separate panel enclosure.
In Saudi Arabia, VAV HVAC control is the preferred air distribution system for Class-A commercial office buildings, where its ability to vary airflow to match occupancy produces 20–30% HVAC energy savings versus constant air volume systems — a key metric for SGBC Mostadam certification and SEC energy efficiency incentive programmes. The King Abdullah Financial District in Riyadh, Jeddah waterfront towers, and KAUST research centre facilities all operate VAV systems with Xenta DDC controllers that provide granular zone temperature control and the occupancy-based control functionality needed for Vision 2030 sustainable building targets.
Razz Middle East distributes TAC Xenta controllers alongside the full Schneider HVAC controls product range, providing system design, TAC Vista and EcoStruxure programming services, controller-to-BMS integration, and commissioning for VAV and AHU HVAC control projects at commercial, hospitality, and industrial buildings across Saudi Arabia.

Key Features & Benefits
- BACnet/IP native communication integrates Xenta 700 with any major BMS platform — EcoStruxure, Metasys, WEBS, Desigo — without protocol gateways, reducing integration cost and complexity.
- Pre-configured VAV application templates for all common terminal sequences (cooling only, heating/cooling, with/without reheat) reduce commissioning time from hours to minutes per zone.
- BACnet MS/TP daisy-chain port enables multiple Xenta 700 controllers to share a single IP router connection, reducing network infrastructure cost in large multi-zone office buildings.
- 6 universal input channels configurable for voltage, current, or resistance accept all common HVAC sensor types — CO₂, temperature, humidity, pressure, occupancy — without specific input modules.
- Freely programmable logic allows custom HVAC sequences for complex AHU applications beyond standard VAV templates, supporting the diverse HVAC system configurations found in Saudi mega-project developments.
- Compact DIN rail enclosure with spring-clamp terminals fits inside VAV terminal unit cabinetry without a separate panel box, reducing installation material and labour cost per zone.
- BACnet priority array support enables integration with fire alarm system override commands, satisfying NFPA 90A and Saudi Civil Defence requirements for HVAC system fire-mode control.
