6.6.1.2 High Temperature Linkage
Context
●
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.
Procedure
Step 1 Log in to the ECC800-Pro WebUI as an administrator.
Step 2 Choose System Settings > Linkage Control.
