(Optional) Setting Teamwork Parameters
Prerequisites
The teamwork group number and addresses for the smart cooling products have been set as follows:
- Teamwork group No.: Group the smart cooling products in same aisle or adjacent areas as one, that is, assign one teamwork group number for them. At most four teamwork groups can be assigned (1–4).
- System address: The address (configurable range: 1-32) of each smart cooling product in the same group must be unique. The smart cooling product with the smallest unit address is the master unit, which collects, processes, and delivers group data.
Context
The parameters in this section are for reference only. Set practical parameter values as required.
Procedure
- On the home screen, tap Teamwork Settings screen, as shown in Figure 6-11. to enter the
- Set teamwork parameters.
All teamwork parameters can be set on the master smart cooling product. Only Teamwork group No., System 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.
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.
Cascade function
When requirement control is enabled, you can enable the cascade function to start standby units if running units cannot meet the cooling capacity requirement.
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.
Outdoor unit auto-cleaning function
Outdoor unit auto-cleaning function: Disable the cooling and dehumidification functions, shut down the compressor system and fluorine pump system, and control the outdoor fans to reversely rotate for 3 minutes.- Disable: Outdoor unit auto-cleaning is not performed.
- Enable: If the teamwork networking is normal, the cooling function of teamwork units is normal, and no high temperature alarm is generated, the teamwork units control the outdoor fans to rotate reversely in sequence during the period from 22:00 to 06:00 to implement auto-cleaning.
- Complete the teamwork settings for all the smart cooling products by performing 1 and 2.
- On the home screen of the display module of any teamwork controlled smart cooling product, tap Figure 6-12. Table 6-5 describes the note for the screen. . If the teamwork control succeeds, the teamwork topology of the smart cooling product in the group is displayed, as shown in
Table 6-5 Notes for the screen

Follow-up Procedure
After you have completed the teamwork settings, perform the following checks to confirm whether the teamwork networking is successful:
- Check whether the number of devices in the topology is the same as the actual number of devices.
- If yes, go to 2.
- If no, check the cable connection and the teamwork settings.
- Check whether the number of running devices in the topology is the same as the actual number of devices.
- If yes, go to 3.
- If no, check the cable connection and the teamwork settings.
- Check whether the number of standby devices in the topology is the same as the actual number of devices.
- If yes, go to 4.
- If no, check the cable connection and the teamwork settings.
- Check whether the number of online devices in the topology is the same as the actual number of devices.
- If yes, the check is complete.
- If no, check the cable connection and the teamwork settings.
