9.1.16 How Do I Set Alarm Parameters?

Prerequisites
Before setting the alarm parameters, get familiar with the coupling relationship
among each parameter.
Configurations of temperature and humidity alarms and main board settings for
the air-cooled devices should comply with the following coupling relationships:
●
