HVAC Requirements

BACnet/IP

Most commercial systems now have some portion of their systems accessible via the BACnet/IP protocol.  BACnet is supported by a wide variety of vendors.  In general, if the point for the zones that the school want to control is visible and writable via BACnet/IP, then E2H should be compatible.  In some cases, the vendor system may require additional components or custom programming.  (examples:  Tridium based systems may require a programmer to export native Tridium points to BACnet/IP points.  Automated Logic systems require a scheduling add-on component to be able to send schedules from E2H)

There are two ways to integrate schedules to BACnet/IP points.

1. E2H sends the occupied state to BACnet binary or multi-state point to change the state of the zone as determined by the schedule
2. E2H sends exception schedules to BACnet schedule points (date/time and values are sent to schedule the occupancy of the zone)

Wi-Fi Thermostats

Some schools may have out-buildings or trailers that have residential type thermostats.  E2H can integrated directly to many of the Wi-Fi vendors to override the setpoints to manage occupied and unoccupied periods based on schedule.

Door Access/ Security

E2H can lock/unlock doors based on events also.  Supported systems include:  JCI/Tyco C-Cure 9000, JCI/Tyco Kantech Entrapass, JCI P-2000, and OpenPath.   Since door access zones will typically have different pre-start times than an HVAC zone, these zones will need to be created separately from HVAC zones and would increase the zone count required.

Zoning

A zone in E2H is a container for a controlled area in the HVAC system.  The site is licensed based on active zones used.   A zone can have 1 or more MLSchedule rooms assigned to it and a zone can command 1 or more physical equipment devices within the zone.  Each zone can be configured with a pre-start time (time to occupy zone prior to event start time) and post-stop time (time to keep system on after the event stop time).  This will ensure the zone is comfortable prior to the event start.
