(Optional) Setting Teamwork Parameters

Procedure

1. On the home screen, tap > Teamwork Settings, to enter the Teamwork Settings screen, as shown in Figure 5-6.
   Figure 5-6 Teamwork Settings
   

2. Set teamwork control parameters.

   All teamwork control parameters can be set on the master smart cooling product. Only Teamwork group num., Air conditioner address, Enable teamwork CAN resistor, Teamwork function and Networking mode can be set on slave smart cooling products. Other parameters of the slave units will be modified by the master unit synchronously. Table 5-5 describes how to set the parameters.

   Table 5-5 Teamwork settings

   Parameter	Description
   Teamwork group num	Specifies the planned teamwork group number. This parameter should be the same for all units in the same teamwork group.
   System address	Specifies the planned unit address. The addresses of units in the same teamwork group must be unique.
   Enable teamwork CAN resistor	If CAN network is selected, set Enable teamwork CAN resistor to Yes for the first and last units. If Enable teamwork CAN resistor is set to No for the first and last units, the CAN communication quality will be affected, and even the teamwork CAN networking will fail. Yes: The teamwork control CAN resistor is enabled for the unit. No: The teamwork control CAN resistor is disabled for the unit.
   Teamwork function	Specifies whether to enable the teamwork function. Set this parameter based on onsite heat load distribution. Disable: A unit operates independently. Enable: A unit operates in team with other units.
   Networking mode	Specifies the networking mode for teamwork control. The networking mode selected on the screen must match the actual networking mode. Otherwise, the teamwork function is unavailable.
   Teamwork parameter synchronization	If Teamwork function and Teamwork parameter synchronization are both set to Enable, you can select Set Local or Set Teamwork when setting parameters. NOTE: Set Local: Set parameters for the local unit. Set Teamwork: Set parameters for all units in a teamwork group.
   Number of systems in this group	Specifies the total number of units in this group. The value is an integer ranging from 1 to 32. NOTE: This parameter is displayed after Teamwork function is set to Enable.
   Number of running systems in this group	Specifies the number of running units in this group. The value is an integer ranging from 1 to the value of Number of systems in this group. NOTE: This parameter is displayed after Teamwork function is set to Enable.
   Percentage of units allowed to dehumidify in this group	Set Percentage of units allowed to dehumidify in this group based on site requirements. NOTE: You are advised to retain the default value. The number of units that perform the dehumidification function is controlled to prevent all units in the group from starting dehumidification at the same time, thereby avoiding supercooling and temperature fluctuation in the equipment room. Number of units allowed to dehumidify is the roundup value of Total number of systems in this group multiplied by Percentage of units allowed to dehumidify in this group. The units allowed to dehumidify are automatically deployed among all running units. If the anti-competitive running mode of the teamwork group is dehumidification, the master unit sends the anti-competitive running flag whose value is dehumidification allowed to the units allowed to dehumidify.
   Rotation function	Indicates whether to allow the smart cooling products to work as the standby device in turn, maximizing their service life. NOTE: It is recommended that the function be enabled when the load is even.
   Rotation period	Number of days for rotation (1–30).
   Rotation time	Specifies the start time of rotation for the active and standby units. 24 time points in a day (0–23).
   Forced rotation	Indicates whether to enable forced rotation regardless of the specified rotation time. After a forced rotation, the rotation period starts again.
   Requirement control	Indicates whether to enable or disable the requirement control function on the master unit. When Requirement control is set to Disable, the master unit does not synchronize operating data to slave units, and all the smart cooling products in the group operate based on their own requirements, not referring to the mode delivered by the master unit. When Requirement control is set to Anti-competitive running, the master unit synchronizes operating data (the temperature and humidity control type and set points of the master unit) to the slave units, and all the smart cooling products in the group refer to the mode delivered by the master unit. When Requirement control is Indoor fan unified control, all smart cooling product fans in the group rotate at the same speed.
   Cascade function	When requirement control is enabled, you can enable the cascade function to start standby units if running units cannot meet the cooling requirement.
   Differential pressure sharing	If this parameter is set to Enable, the smart cooling product, which is not equipped with a differential pressure sensor in the group, is logically controlled by using the highest, smallest, and average values of the data acquired by the differential pressure sensors that have been installed.
   Cold aisle temperature and humidity sharing	This function can be enabled only when at least one smart cooling product in the teamwork group is equipped with cold aisle T/H sensors. If this function is enabled, the master unit in the teamwork group collects the cold aisle temperature and humidity values from all units equipped with cold aisle sensors, and synchronizes the temperature and humidity control type and setpoints to all slave units.
   Hot aisle temperature and humidity sharing	This function can be enabled only when at least one smart cooling product in the group is equipped with hot aisle T/H sensors. If this function is enabled, the master unit in the teamwork group collects the hot aisle temperature and humidity values from all units equipped with hot aisle sensors, and synchronizes the temperature and humidity control type and setpoints to all slave units.

3. Complete the teamwork settings for all the smart cooling products by performing 1 and 2.
4. On the home screen of the display module of any teamwork controlled smart cooling product, tap . If the teamwork control succeeds, the teamwork topology of the smart cooling product in the group is displayed.
   Figure 5-7 Teamwork topology
   

   No.	Item	Note
   1	On/Off	On: The device is started. Off: The device is shut down.
   2	01/02/03...	Indicates the device address. The smallest address is for the master unit and the rest are for slave units. If the master unit is offline, the online device with the smallest address is selected to be the new master.
   3	Active/Standby	Active: An active unit properly responds to control requirements. Standby: A standby unit responds to control requirements only if an active unit is faulty (critical alarm, shutdown, or offline) or the active unit cannot meet cooling requirements.
   4	M/S	M: master unit S: slave unit A blue icon indicates that the unit is operating, and a gray icon indicates that the unit is idle.
   5	Frame: green/non-green	A green frame indicates the current unit, as shown in . Devices without a green frame indicate other devices in the teamwork group.
   6	Background color: red/bright gray	Red indicates that the unit has generated a critical alarm, as shown in . Bright gray indicates that the device is operating without any critical alarms.

   If teamwork succeeds, the teamwork icon is green. If teamwork fails, the teamwork icon is red. If teamwork mode is disabled, the teamwork icon is gray.
