A system for displaying the values of reported conditions of a building air-conditioning system wherein a reporting message from a remote station has a first portion for selecting the engineering units for the normalized condition value reported in a second portion of the message so that upon the message being received at a central station the first portion of the message is used to retrieve from a memory the engineering unit data to be applied to the normalized condition value to report the condition as a true reported value. |
