Calendar Event - Honeywell 900 User Manual

Calendar Event

The Calendar Event compares user-entered time-and-date setpoints to the real-time clock to generate digital
Event outputs. These Event outputs can be integrated into a control strategy to activate time-synchronized
activities. For example, the Event outputs can be used to schedule when to turn lights on and off in an
office building. Each Calendar Event block supports up to eight Event outputs.
In addition, the block allows you to configure up to five sets of time-and-date setpoints, called Setpoint
Groups. These Setpoint Groups can be used to activate different sets of time-and-date setpoints to handle
different conditions. Using the example of office building lights, Setpoint Groups can be used to activate a
different set of time-and-date setpoints for each season of the year (Spring, Summer, Fall, and Winter).
Each Calendar Event block supports five Setpoint Groups. The screen shown above is an example of one of
these Setpoint Groups. You can select which Setpoint Group is in effect; the values in each column will
change according to the Setpoint Group you select. Each Setpoint Group is editable.
The block also allows you to configure up to 16 Special Days. On these Special Days the Calendar Event
Block will override its normal Event processing for a 24-hour period. For example, you can configure
selected Event outputs to remain off on designated holidays.
