Humidity falling below the hysteresis level re-enables alarm traps for the next alarm
event. An upper limit of 25 and a hysteresis threshold of 1.5 yield a threshold limit of
23.5.
The humidity level again beings to rise and again exceeds the upper limit, however
this time an alarm trap is again generated.
The Hysteresis feature acts on the following Temperature and Humidity thresholds:-
Upper Control Limit (UCL)
Lower Control Limit (LCL)
Upper Warning Limit (UWL)
Lower Warning Limit (LWL)
The inverse of the above description is true when applied to Temperature and
Humidity lower control and warning limits.
As stated above the hysteresis threshold is user configurable using the menu options
detailed previously.
