CORRIGO VENTILATION 3.6 MANU

Appendix Frequency converters and EC
controllers for heat exchangers
Version 3.6 and later of Corrigo ventilation supports the frequency converters and/or EC controllers
for heat exchangers listed below:
• Vacon NXL
• Lenze
• Omron V1000
• Emerson Commander
• LS
• EBM
• Danfoss FC 101
• ABB ACS
• EC Blue
Heat exchanger via Modbus:
• RHC 200
• VariMax25M
When communicating via frequency converters through Modbus, it is sometimes necessary to change
certain settings in the frequency converter.
Two parallel connected frequency converters for supply air and two parallel connected frequency
converters for extract air can be run. The supply air fan will have address 1 and the parallel supply air
fan address 3. The extract air fan will have address 2 and the parallel extract air fan address 4.
Below is described what settings are necessary in the various models:
Vacon NXL
No settings necessary. Vacon NXL frequency converters are controlled via Modbus. Communication,
alarms and certain indications can be read:
The following signals can be read/written from/to the frequency converter:
