Real Time Clock

unleashes the full potential of HVAC

Stand-alone unit

VLT® HVAC Drive provides intelligent

stand-alone functionality via:

• Built-in Real Time Clock

• Programmable actions

• Smart Logic Controller

• 4 auto-tuned PID controllers.

Automatic Energy Optimisation

The standard feature AEO provides

optimized motor magnetisation at all

speeds and loads.

This increases energy eﬃ ciency by

5-15% at partial loads.

Flow compensation

Signiﬁ cant energy savings and reduc-

ed installation costs are provided by

ﬂ ow compensation in both fan and

pumps systems. A pressure sensor

mounted close to the fan or pump

provides a reference enabling pressure

to be kept constant at the discharge

end of the system. The drive constant-

ly adjusts the pressure reference to

follow the system curve.

Energy monitoring

The VLT® HVAC Drive provides a com-

plete range of energy consumption

information. Choose to divide absolute

energy consumption into hours, days

or weeks. Or choose to monitor a load

proﬁ le for the application.

Energy analysis

This data can even be uploaded to a

VLT® Energy Box – PC software that

performs in-depth real life/true energy

analysis of your application and dis-

plays the payback time for the drive.

The VLT® HVAC Drive has an award winning Local

Control Panel and a well-structured menu system

that ensures fast commissioning and trouble-free

operation of the many powerful functions.

The VLT® HVAC Drive can be remote commissioned

and monitored through a USB pluggable cable or

BMS network communications. VLT® Set up

Software MCT 10 and Language Changer make

drive operation child’s play.
