Dedicated HVAC features Auto tuning of the PI controllers
With auto tuning of the PI controllers, the drive monitors how the system reacts on corrections made by the drive - and learns from it, so that precise and stable operation is achie ved quickly.

Automatic Energy Optimization
The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.

Energy monitoring
The VLT HVAC Drive provides a complete range of energy consumption information, which helps identify low-efficiency components in the HVAC system.

Automated Resonance Monitoring
The drive can easily be set to avoid frequency bands at which connected fans create resonances in the ventilation system. This reduces installation time and system wear.

Fan Belt Monitoring
From the relation between current and speed, the VLT HVAC Drive is able to reliably recognize a broken belt.

Fire Override Mode
In Fire Override Mode, the VLT HVAC Drive will not react to control signals, warnings or alarms. It will continue reliable operation as long as possible and run until it is eventually destroyed itself to ensure that fire escapes remain free of smoke

Set point in temperature
The VLT HVAC Drive calculates the actual room temperature from the pressure in the cooling media and refines compressor operation accordingly without the need for additional software, sensors or controllers. This feature allows less expensive pressure sensors to be used.

Pipe Fill Mode
Enables controlled (closed loop) filling of pipes. Prevents water hammering, bursting water pipes or blowing off sprinkler heads.

End of Pump Curve detects breaks and leakage
The feature detects breaks and leakage. End of curve triggers an alarm, shuts off the pump, or performs another userdefined action.

Dry Pump Protection lowers maintenance costs
The VLT HVAC Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements.

Standard cascade controller
The in-built cascade controller controls up to three pumps with fixed lead pump.

Motor Alternation
This built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents sticking of the pump. An internal timer assures equal usage of the pumps.

Flow compensation
The flow compensation feature reduces the pressure set point according to the flow - which saves energy.

Initial/Final Ramp
The initial ramp provides fast acceleration of pumps to minimum speed, from where the normal ramp takes over. This prevents damage on thrust and bearings. Sensorless Pressure or Flow Control

Safety
The VLT HVAC Drive can optionally be delivered with the safe stop functionality suitable for category 3 installations according to EN 954-1. This feature prevents the drive from starting unintended
