(Optional) Setting the Indoor Fan Control Type
If a micro differential pressure sensor is installed and the pressure difference control is required, set
Air-side difference pressure sensor type to 0–50 Pa, and set the Indoor fan control type to
Pressure diff ctrl. It is recommended that the Indoor fan pressure difference setpoint retain the
default value. If there are hot spots onsite, you can increase the value. Path: Settings > System

1. Teamwork group no.: One teamwork networking can contain four groups at most. They must have
the same teamwork control number and can be assigned 1–4 respectively.
2. Smart cooling product address: In a teamwork control group, each smart cooling product address
(1-32) must be unique, and the smart cooling product with minimum address is the master smart
cooling product.
3. Networking mode: The networking mode set on the screen must be consistent with the actual
networking mode. CAN network indicates teamwork control over a CAN bus, MAC_CAN network
teamwork control over an FE port.
4. Enable teamwork CAN resistor: In CAN networking, set this parameter for the first and last smart
cooling products to Yes.
5. Number of smart cooling products in this group: Indicates the number of precision smart cooling
products in a group. The value is an integer ranging from 1 to 32.
6. Number of running smart cooling products in this group: Specifies the number of running
NetCol5000-Cs in a group. The value ranges from 1 to the number of NetCol5000-Cs in the group.
7. Rotation function: Enable the active and standby smart cooling products to work alternately. This
function is recommended when the heat load is even.
8. When Requirement control is set to Anti-competitive running, the master smart cooling product
synchronizes operating data (parameters such as the T/H control type, temp set point, humid set
point for the master smart cooling product) to the slave smart cooling product, and all the precision
smart cooling products in the group refer to the mode delivered by the master smart cooling
product. When Requirement control is set to Disable, all the smart cooling products operate
based on their own requirements. When the requirement control is Indoor fan unified control or
Central load distribution, all smart cooling product fans in the group rotate at the same speed.
The table uses 8 smart cooling products in CAN teamwork as an example.
