5.4.2.2  Control Humidity Alarms 

If the control humidity sensor is enabled, high and low 
alarms may be enabled and set to specific trip points. The 
offset behaves in the same manner as described in section 
5.4.2.1. It applies to both the high and low alarms. 

 

 

 

 

 

 

 

 

 

5.4.2.3  Limit Temperature Alarms 

If the limit temperature sensor is enabled, high and low 
alarms may be enabled and set to specific trip points. The 
offset behaves in the same manner as described in section 
5.4.2.1. It applies to both the high and low alarms.
