Functions
⚫
When only one NetCol5000-C is running, the controller provides logic control of
components in the NetCol5000-C to meet temperature and humidity requirements.
⚫
The 7-inch true color-sensitive LCD allows you to set parameters for the NetCol5000-C
and query its status.
⚫
When multiple NetCol5000-Cs work cooperatively, the controller optimally distributes
the heat load to reduce power consumption and provides backup to improve reliability.
