Commissioning Procedure 11.3
• Before commissioning,
ensure that the stop valves
on the indoor and outdoor
units are open, and that
the electric heating belt of
the crankcase in the
compressor has been
preheated for 12 hours.
• Ensure that no
combustion-supporting
materials (air or additives)
enter the air conditioning
system during
commissioning. Huawei
shall not be liable for any
risks and losses thus
incurred.
•
The electric heater and
humidifier can not work at
the same time.
c. Teamwork unit address : In a teamwork control group, each Teamwork unit address must
be unique, and the address of one smart cooling product must be 1 (master smart cooling
product).
d. Total number of units : 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 units : Number of running units ≤ Total number of units . 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, 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 , 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.
