Trend launches new generation of controllers
Trend Control System has launched the first two models in a new generation of controllers for building energy management systems. The IQ411 and IQ412 both offer a combination of advanced capabilities not found on other building-services controllers, even much larger ones. A range of features simplifies installation, engineering and commissioning. These new units can be used to provide energy-efficient, highly distributed local control of services such as underfloor heating, natural ventilation, small air handlers and air-conditioning terminal units.
They have been designed as drop-in replacements for Trend IQ211/212 and IQ70 controllers that may be nearing the end of their operational life. Swapping one controller for another, including uploading or reloading the control strategy, takes no more than five minutes.
These controllers incorporate a web server and have Ethernet connectivity. There are versions for connecting to a Trend LAN and/or BACnet. They are fully compatible with earlier Trend control and monitoring equipment and can be seamlessly integrated within existing Trend systems.
New control modules include an integrator function and virtual heat meter for monitoring energy usage.
Applications include providing small pockets of distributed intelligence around a building to provide a cost-effective means of achieving advanced control. They can also provide all the control and monitoring required in premises with simple services such as a boiler and a radiator circuit.
