3.10.1 High- and Low-Temperature and Humidity Events
High- and low-temperature and humidity alarms can be set for both the internal and optional
external sensors. If a sensor reading exceeds a preset threshold, a warning will appear. These
warnings are ignored after unit startup for a minimum of 1 minute. To increase the delay to warn, see
3.10 - Event Types and Properties. The threshold settings are located in both the User and Service
menus under Set Alarms.
To apply threshold limits on the internal cooling unit sensors, the Return Sensor Alarms must be
To apply threshold limits on the internal cooling unit sensors, the Return Sensor Alarms must be
enabled. The high and low temperature and humidity internal sensor thresholds can then be set. To
apply threshold limits on the optional external sensors, the Sensor A alarms must be enabled. The
high and low temperature and humidity external sensor thresholds can then be set. If no external
sensors are connected to the unit, it is recommended that the Sensor A Alarms be disabled.
