makes HVAC operation child’s play
Achieve the lowest cost of ownership with a premier drive dedicated to ventilation, heating, and refrigeration applications. 

Features and Benefits

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 achieved quickly. 

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

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

Built-in cascade controller
Control up to three pumps with fixed lead pump.

- Coated circuit boards 
All standard PCBs conform with class 3C2 (IEC 60721-3-3). If used in especially harsh conditions, it is possible to order a special coating that complies with class 3C3.

- Fire Override Mode
Safety feature that ensures fire escapes remain free of smoke by preventing the drive from reacting to control signals, warnings, or alarms. Instead, it continues reliable operation for as long as possible and runs until it eventually fails.

- Energy Optimization
Standard feature that optimizes motor magnetization at all speeds and loads. Increases energy efficiency by 5–15% for partial loads. 

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

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

-  Built in DC coils and RFI filters - no EMC concerns
