enteliTOUCH BACnet 7 Touchscreen LCD BMS Controller

The enteliTOUCH (eTCH-7E) is a 7-inch diagonal, high resolution, wide-screen format, color LCD, used for interfacing with the Delta Controls Building Automation System. It uses BACnet™ to communicate with controllers on a local area network, and across the Internet. Expansion modules can add MS/TP communication, or allow the enteliTOUCH to act as a wireless coordinator to enteliMESH products. User created graphics allow the enteliTOUCH to be completely customized for a given application.


enteliTOUCH allows operators to monitor and manage building automation systems by using custom real-time graphics. The enteliTOUCH display 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.

With available expansion modules, the enteliTOUCH can communicate with a BACnet MS/TP subnet or enteliMESH wireless controllers and sensors to form a complete control solution.
