Trend BMS Systems

Buildings are subjected to changeable and at times extreme weather conditions.

Providing owners with the satisfactory data that enables them to control and monitor their building, whilst at the same time providing a suitable working environment for those within, becomes a difficult requirement to fulfill.

Building Management Systems monitor and control services such as heating, ventilation and air-conditioning, ensuring they operate at maximum levels of efficiency and economy. This is achieved by maintaining the optimum balance between conditions, energy usage and operating requirements.

Our key components are:

  • Controllers - Microcomputer controllers receive signals from field devices and according to their programmed operating parameters, take action to control plant equipment.
  • Supervisors - Supervisors view or amend the system data as well as providing a wide range of energy analysis and maintenance functions.
  • Networks - Networks allow devices to communicate across a physical distance either locally, across a wide area network, or remotely by using standard browser technology. This means information can be accessed from anywhere in the world, ensuring total building continuity.
  • Field Devices - Field devices send or receive data directly to controllers for either local or remote control & monitoring. If you don’t measure or monitor an area or item you can not control it.

System Architecture


IQView4 Local Touch Screen Display

The IQView4 is a touch screen display which provides an interface to an IQ controller by way of its local supervisor port. It allows access to modules, graphs, alarms, and timezones.

It has a 4.3 (109.2 mm) LCD touch screen colour display, and is housed with the electronics in a single unit suitable for rear panel mount applications. As well as a Home screen, the unit can be programmed with a number of favourite screens.

IQ3 Web Enabled Controllers

The IQ3 controllers are Building Management System controllers that use Ethernet and TCP/IP networking technologies. Each controller incorporates a web server which can deliver user specific web pages to a PC or mobile device running internet browser software. If a system is set up with the correct connections, a user with the appropriate security codes can monitor or adjust the controller from any Internet access point in the world. It is also compatible with the traditional IQ system protocol.
