over the active Internet connection to the Simple Mail Transfer Protocol (SMTP) server using the configured e-mail destination parameters. The SMTP server passes the message into the e-mail account specified. The time required for the alarm text to reach an e-mail Inbox depends on several factors, which include the speed and avail- ability of the e-mail server.

Text Messages

The System Manager or Coordinator can send alarms to cellular phones that use the SMS protocol. When a critical alarm occurs, the device constructs a message with an SMS format, then sends it over the active Internet connection to the SMS server using the configured text message destination parameters. The SMS server sends the mes- sage to the subscriber’s cellular phone account. The time required for the alarm text to reach a cellular phone depends on several factors, including the speed and availability of the service provider.

Zones, Groups, and Members

A Zone is an area of the building where temperature is under the control of a single Zone Controller. A small office, classroom, warehouse, or gymnasium can be consid- ered one zone.

A Group is a collection of zones that operate on the same schedule or temporary occu- pancy state. Each group can support up to 24 zones for COB RTU systems or 32 zones for VAV RTU systems. Each Coordinator can control up to 4 groups.

Lastly, a Member is something you can schedule, which can be a Group, CV RTU, or IOM output point. The Member List is the screen that shows the currently defined members.

Event Scheduling

You can define up to 24 event schedules at the System Manager and up to 4 event schedules on the Zone Coordinator, if the Zone Coordinator is not reporting to a Sys- tem Manager. Each schedule consists of a unique schedule name and a pair of two occupied times and two unoccupied times for each day of the week. Each schedule also has one or more members. A member is something that can be scheduled.

The last commanded state by a schedule for a particular day rolls over into the next day (that is, remains the same) until the next commanded state for the new day occurs. If the Coordinator reports to a System Manager, the Coordinator scheduling is not used. In this case, the System Manager defines and executes all Coordinator schedules.

Temporary Occupancy Override

Temporary Occupancy Override allows you to force a group of zones into a temporar- ily occupied state for a period of time, called the time-out delay. You can do this from the Zone Details screen or by pushing the temporary occupancy button on the thermo- stat. This action causes the zone, and all other zones in the same Group, to become temporarily occupied together. The system ignores all occupancy schedules for these zones during the time-out period. Once the time-out delay expires, the zones return to their normal occupancy schedule.
