Event Query Schedule

To set the frequency of queries of schedule data, select the Event Query Schedule tab in the Events2HVAC Options window.

Shorter or longer intervals can be specified by selecting the Continuous option and defining the desired interval in the Update Interval box. Refer to the 

Warning:  Do not set your query interval time too fast.  At each query, the event provider is queried and the command queue is re-queued.  The amount of time required to query depends on the speed of the network, the number of commands queued, and the server resources.  Start at a 2 hour frequency or higher and adjust faster if your site can handle the increased load.
