existing building management system.

Its simple 'press and turn' operation makes setting and changing heating options easy.

A plain text display allows input of system operations and communicates boiler diagnostics.

They can be fitted directly to the main control unit or wired to the boiler from the living or working space (as a room thermostat).

EMS is a state of the art intelligent control system that uses a standard operating structure to ensure smooth and continuous communication between the automatic firing in the boiler, and the heating system controls.
