CGAV - Modular

85Kw - 150Kw

Main features

  • Installation space is reduced to less than half: Compact design with a 43% reduction in size compared to our conventional model (CXAM052) allowing for effective use of available space.
  • Control multiple units with a single device: Control up to 20 units with a single module controller. Fine control of each unit can be configured within the respective controller panel.
  • Great operability without needing a user manual: The module controller allows for up to 20 units to be managed from one device, and the 7-inch touch screen enables intuitive operation.
  • Monitor from your computer or smart phone: The control software not only allows access from computers but also allows access to the monitoring system using mobile terminals such as smart phones and tablets. Single-touch operation, color-changing animations and other features make for an easy-to-read, easy-to-operate monitoring screen that is intuitive to change.
  • Simultaneous monitoring of multiple facilities: Tracer ESTM control software is especially designed for use at large scale facilities, allowing for centralised control of buildings and facilities over a range of sites and realising improved awareness and control in real-time.

Customer benefits

Tracer™ SC Control

The Tracer® SC is an intelligent field panel that communicates with unit controllers (LON or BACnet) that provide standalone control of HVAC equipment. The Tracer® SC scans all unit controllers to update information and coordinate building control, including building subsystems such as VAV and chilled water systems. The LAN allows building operators to manage these varied components as one system using web access.
