The Nibe PWB 2 Inverter with Reactor (Part No. 918499) is a specialized electronic control board used in Nibe heat pump systems, particularly models like the AMS 10-8 and F2040-8. Here's a quick breakdown of what it is and what it does:

Key Functions

• Inverter Control: Manages the modulation of the compressor to optimize heating performance.
• System Communication: Interfaces with the main control board (PWB1) and sensors to coordinate system behaviour.
• Energy Efficiency: Helps maintain stable temperatures and reduce energy consumption by adjusting output based on demand.

Technical Details

• Manufacturer: Nibe Energy Systems
• Includes: PWB2 inverter board and reactor (choke)
• Application: Designed for specific Nibe heat pump models; not interchangeable across all units.

Installation Notes

• Should be installed with the system powered off and discharged.
• Requires reconnection of multiple cables and may need system commissioning afterward.
