Description: The DHMI is a 7-inch diagonal, high resolution, wide-screen format, color LCD used for interfacing with the Delta Controls building Automation System. The Delta DHMI uses BACnet over Ethernet to communicate with controllers on a local area network. User created graphics allow the DHMI to be completely customized for a given application.
Application: The DHMI allows operators to monitor and manage building HVAC systems by using custom real-time graphics.
The Delta DHMI can be wall or panel mounted in mechanical rooms, which allows for monitoring and setting schedules for air handlers, boilers, chillers and other mechanical equipment.
It is also designed to be mounted in public spaces. The Delta DHMI can be used as a small building interface making it simple to do things such as change occupancy schedules, adjust temperature setpoints and view floor layouts.
