When a smart module actuator is configured, you need to set parameters for the
smart module actuator. The setting process is similar.
The ECC800-Pro implements high temperature linkage. If it detects high
temperature alarms by interacting with multi-functional sensors and all smart
cooling products fail to communicate with the ECC800-Pro, the ECC800-Pro
opens skylights based on the alarm status to facilitate heat dissipation.
The default status of high temperature linkage is off. Set it based on the
actual situation.
