Requirement control
a. Teamwork function: Disable indicates that the smart cooling product operates separately.
Enable indicates that the smart cooling product operates in team with other smart cooling
products.
b. Teamwork group no.: One ECC800 supports a maximum of four teamwork control groups. To
increase the response speed, it is recommended that one teamwork control group is connected.
c. Air conditioner address: In a teamwork control group, each Air conditioner address must be
unique, and the address of one smart cooling product must be 1 (master smart cooling product).
d. Number of air conditioners in this group: Total number of precision smart cooling products in
the group. The parameter can only be set on the master smart cooling product.
e. Number of running air conditioners in this group: Number of running air conditioners in
this group ≤ Number of air conditioners in this group. Assign the address 1 to the master
smart cooling product, and assign addresses starting from 2 consecutively to all active smart
cooling products in a group. Remaining smart cooling products will be regarded as standby
smart cooling products. The parameter can only be set on the master smart cooling product.
f. Forced Rotation: Disable or enable the active and standby smart cooling products to work
alternately to maximize their service life. This function is recommended when the heat load is
even. The parameter can only be set on the master smart cooling product. When Rotation is
Enable, the parameters for Rotation period and Rotation time can be set based on the
customer's requirements.
g. When Requirement control is set to Competitive running avoidance, the master smart
cooling product synchronizes operating data (parameters such as the T/H control type,
temperature set point, humidity 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, the master smart cooling product does not synchronize operating data to the slave
smart cooling product, and all the smart cooling products operate based on their own
requirements, not referring to the mode delivered by the master smart cooling product. The
parameter can only be set on the master smart cooling product.
